Product overheating can cause electric shock, fire and/or serious personal injury or even death. Electrical safety If the information on electrical safety is not observed either at all or to the extent necessary, electric shock, fire and/or serious personal injury or death may occur. 1. Prior to switching on the product, always ensure that the nominal voltage setting on the product matches the nominal voltage of the mains-supply network. If a different voltage is to be set, the power fuse of the product may have to be changed accordingly. 2. In the case of products of safety class I with movable power cord and connector, operation is permitted only on sockets with a protective conductor contact and protective conductor. 3. Intentionally breaking the protective conductor either in the feed line or in the product itself is not permitted. Doing so can result in the danger of an electric shock from the product. If extension cords or connector strips are implemented, they must be checked on a regular basis to ensure that they are safe to use. 4. If there is no power switch for disconnecting the product from the mains, or if the power switch is not suitable for this purpose, use the plug of the connecting cable to disconnect the product from the mains. In such cases, always ensure that the power plug is easily reachable and accessible at all times. For example, if the power plug is the disconnecting device, the length of the connecting cable must not exceed 3 m. Functional or electronic switches are not suitable for providing disconnection from the AC supply network. If products without power switches are integrated into racks or systems, the disconnecting device must be provided at the system level. 5. Never use the product if the power cable is damaged. Check the power cables on a regular basis to ensure that they are in proper operating condition. By taking appropriate safety measures and carefully laying the power cable, ensure that the cable cannot be damaged and that no one can be hurt by, for example, tripping over the cable or suffering an electric shock.

1171.0000.42 - 09 Page 4 6. The product may be operated only from TN/TT supply networks fuse-protected with max. 16 A (higher fuse only after consulting with the Rohde & Schwarz group of companies). 7. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and all the way into the socket provided for this purpose. Otherwise, sparks that result in fire and/or injuries may occur. 8. Do not overload any sockets, extension cords or connector strips; doing so can cause fire or electric shocks. 9. For measurements in circuits with voltages Vrms > 30 V, suitable measures (e.g. appropriate measuring equipment, fuse protection, current limiting, electrical separation, insulation) should be taken to avoid any hazards. 10. Ensure that the connections with information technology equipment, e.g. PCs or other industrial computers, comply with the IEC 60950-1 / EN 60950-1 or IEC 61010-1 / EN 61010-1 standards that apply in each case. 11. Unless expressly permitted, never remove the cover or any part of the housing while the product is in operation. Doing so will expose circuits and components and can lead to injuries, fire or damage to the product. 12. If a product is to be permanently installed, the connection between the protective conductor terminal on site and the product's protective conductor must be made first before any other connection is made. The product may be installed and connected only by a licensed electrician. 13. For permanently installed equipment without built-in fuses, circuit breakers or similar protective devices, the supply circuit must be fuse-protected in such a way that anyone who has access to the product, as well as the product itself, is adequately protected from injury or damage. 14. Use suitable overvoltage protection to ensure that no overvoltage (such as that caused by a bolt of lightning) can reach the product. Otherwise, the person operating the product will be exposed to the danger of an electric shock. 15. Any object that is not designed to be placed in the openings of the housing must not be used for this purpose. Doing so can cause short circuits inside the product and/or electric shocks, fire or injuries. 16. Unless specified otherwise, products are not liquid-proof (see also section "Operating states and operating positions", item 1). Therefore, the equipment must be protected against penetration by liquids. If the necessary precautions are not taken, the user may suffer electric shock or the product itself may be damaged, which can also lead to personal injury. 17. Never use the product under conditions in which condensation has formed or can form in or on the product, e.g. if the product has been moved from a cold to a warm environment. Penetration by water increases the risk of electric shock. 18. Prior to cleaning the product, disconnect it completely from the power supply (e.g. AC supply network or battery). Use a soft, non-linting cloth to clean the product. Never use chemical cleaning agents such as alcohol, acetone or diluents for cellulose lacquers. Operation 1. Operating the products requires special training and intense concentration. Make sure that persons who use the products are physically, mentally and emotionally fit enough to do so; otherwise, injuries or material damage may occur. It is the responsibility of the employer/operator to select suitable personnel for operating the products.

1171.0000.42 - 09 Page 5 2. Before you move or transport the product, read and observe the section titled "Transport". 3.

Before you start processing the product mechanically and/or thermally, or before you take it apart, be sure to read and pay special attention to the section titled "Waste disposal/Environmental protection", item 1. 5. Depending on the function, certain products such as RF radio equipment can produce an elevated level of electromagnetic radiation. Considering that unborn babies require increased protection, pregnant women must be protected by appropriate measures. Persons with pacemakers may also be exposed to risks from electromagnetic radiation. The employer/operator must evaluate workplaces where there is a special risk of exposure to radiation and, if necessary, take measures to avert the potential danger. 6. Should a fire occur, the product may release hazardous substances (gases, fluids, etc.) that can cause health problems. Therefore, suitable measures must be taken, e.g. protective masks and protective clothing must be worn. 7. Laser products are given warning labels that are standardized according to their laser class. Lasers can cause biological harm due to the properties of their radiation and due to their extremely concentrated electromagnetic power. If a laser product (e.g. a CD/DVD drive) is integrated into a Rohde & Schwarz product, absolutely no other settings or functions may be used as described in the product documentation. The objective is to prevent personal injury (e.g. due to laser beams). 8. EMC classes (in line with EN 55011/CISPR 11, and analogously with EN 55022/CISPR 22, EN 55032/CISPR 32)  Class A equipment: Equipment suitable for use in all environments except residential environments and environments that are directly connected to a low-voltage supply network that supplies residential buildings Note: Class A equipment is intended for use in an industrial environment.

En caso de que un producto Rohde & Schwarz contenga un producto láser (p. ej. un lector de CD/DVD), no debe usarse ninguna otra configuración o función aparte de las descritas en la documentación del producto, a fin de evitar lesiones (p. ej. debidas a irradiación láser). 8. Clases de compatibilidad electromagnética (conforme a EN 55011 / CISPR 11; y en analogía con EN 55022 / CISPR 22, EN 55032 / CISPR 32)  Aparato de clase A: Aparato adecuado para su uso en todos los entornos excepto en los residenciales y en aquellos conectados directamente a una red de distribución de baja tensión que suministra corriente a edificios residenciales. Nota: Los aparatos de clase A están destinados al uso en entornos industriales. Estos aparatos

1171.0000.42 - 09 Page 13 pueden causar perturbaciones radioeléctricas en entornos residenciales debido a posibles perturbaciones guiadas o radiadas. En este caso, se le podrá solicitar al operador que tome las medidas adecuadas para eliminar estas perturbaciones.  Aparato de clase B: Aparato adecuado para su uso en entornos residenciales, así como en aquellos conectados directamente a una red de distribución de baja tensión que suministra corriente a edificios residenciales. Reparación y mantenimiento 1. El producto solamente debe ser abierto por personal especializado con autorización para ello. Antes de manipular el producto o abrirlo, es obligatorio desconectarlo de la tensión de alimentación, para evitar toda posibilidad de choque eléctrico. 2. El ajuste, el cambio de partes, el mantenimiento y la reparación deberán ser efectuadas solamente por electricistas autorizados por Rohde & Schwarz. Si se reponen partes con importancia para los aspectos de seguridad (p. ej. el enchufe, los transformadores o los fusibles), solamente podrán ser sustituidos por partes originales. Después de cada cambio de partes relevantes para la seguridad deberá realizarse un control de seguridad (control a primera vista, control del conductor de protección, medición de resistencia de aislamiento, medición de la corriente de fuga, control de funcionamiento). Con esto queda garantizada la seguridad del producto. Baterías y acumuladores o celdas Si no se siguen (o se siguen de modo insuficiente) las indicaciones en cuanto a las baterías y acumuladores o celdas, pueden producirse explosiones, incendios y/o lesiones graves con posible consecuencia de muerte. El manejo de baterías y acumuladores con electrolitos alcalinos (p. ej. celdas de litio) debe seguir el estándar EN 62133. 1. No deben desmontarse, abrirse ni triturarse las celdas. 2. Las celdas o baterías no deben someterse a calor ni fuego. Debe evitarse el almacenamiento a la luz directa del sol. Las celdas y baterías deben mantenerse limpias y secas. Limpiar las conexiones sucias con un paño seco y limpio. 3. Las celdas o baterías no deben cortocircuitarse. Es peligroso almacenar las celdas o baterías en estuches o cajones en cuyo interior puedan cortocircuitarse por contacto recíproco o por contacto con otros materiales conductores. No deben extraerse las celdas o baterías de sus embalajes originales hasta el momento en que vayan a utilizarse. 4. Las celdas o baterías no deben someterse a impactos mecánicos fuertes indebidos. 5. En caso de falta de estanqueidad de una celda, el líquido vertido no debe entrar en contacto con la piel ni los ojos. Si se produce contacto, lavar con agua abundante la zona afectada y avisar a un médico. 6. En caso de cambio o recarga inadecuados, las celdas o baterías que contienen electrolitos alcalinos (p. ej. las celdas de litio) pueden explotar. Para garantizar la seguridad del producto, las celdas o baterías solo deben ser sustituidas por el tipo Rohde & Schwarz correspondiente (ver lista de recambios). 7. Las baterías y celdas deben reciclarse y no deben tirarse a la basura doméstica. Las baterías o acumuladores que contienen plomo, mercurio o cadmio deben tratarse como residuos especiales. Respete en esta relación las normas nacionales de eliminación y reciclaje.

Shock hazard Before replacing a fuse, make sure that the instrument is switched off and disconnec- ted from all power supplies. Always use fuses supplied by Rohde & Schwarz as spare parts, or fuses of the same type and rating. 2.4 Connecting External Accessories The equivalent USB ports on the front and/or rear panel of the R&S SMC can be used to connect a variety of accessories. In addition the instrument provides interfaces for network integration (see Chapter 2.6, "Setting Up a Network (LAN) Connection", on page 34). 2.4.1 Connecting USB Devices Via the USB ports, you can connect external devices directly to the R&S SMC. If you need more interfaces, you just use an USB hub. Connecting External Accessories

R&S®SMC100A 32 Operating Manual 1411.4060.32 ─ 09 The following list shows various USB devices that can be useful: ● Memory stick for easy transfer of data to/from a computer (for example firmware updates). ● CD-ROM drives for easy installation of firmware applications. ● Keyboard or mouse to simplify the entry of data, comments, file names, etc. ● Power sensors, for example of the NRPxS(N) Power Sensors family. Installing USB devices is easy under Linux, because all USB devices are plug&play. After a device is connected to the USB interface, the operating system automatically searches for a suitable device driver. If Linux does not find a suitable driver, it will prompt you to specify a directory that con- tains the driver software. If the driver software is on a CD, connect a USB CD-ROM drive to the instrument before proceeding. When a USB device is subsequently disconnected from the R&S SMC, the operating system immediately detects the change in hardware configuration and deactivates the corresponding driver. All USB devices can be connected to or disconnected from the instrument during oper- ation. Connecting a memory stick or CD-ROM drive If installation of a memory stick or CD-ROM drive is successful, the operating system informs you that the device is ready to use. The device is made available as a new drive (/usb). The name of the drive is manufacturer-dependent. Connecting a keyboard The keyboard is detected automatically when it is connected. The default keyboard lay- out is English – US. Use the "Setup > Keyboard Settings" dialog to configure the keyboard properties. Connecting a mouse The mouse is detected automatically when it is connected. 2.5 Linux Operating System The instrument uses an embedded Linux operating system. To make sure that the instrument software works properly, certain rules must be adhered to concerning the operating system. Linux Operating System

R&S®SMC100A 33 Operating Manual 1411.4060.32 ─ 09 Risk of causing instrument unusability The instrument is equipped with the Linux operating system. Additional software can therefore be installed on the instrument. The use and installation of additional software may impair instrument function. Thus, run only programs that Rohde & Schwarz has tested for compatibility with the instrument software. The drivers and programs used on the instrument under Linux have been adapted to the instrument. Existing instrument software must always be modified using only update software released by Rohde & Schwarz. The configuration of the operating system is optimally adapted to signal generator functions in the factory. Changes in the system setup are only required when peripher- als like keyboard are installed or if the network configuration does not comply with the default settings (see Chapter 2.6.1, "Connecting the Instrument to the Network", on page 34). After the R&S SMC is started, the operating system boots and the instrument firmware is started automatically. Accessing Operating System No access to the operating system is required for normal operation. All necessary system settings can be made in the "Setup" dialog. The R&S SMC provides an internal flash memory, it does not contain a disk drive. The flash memory holds the operating system, the firmware and the stored data. Data transfer is possible via a memory stick connected to a USB interface. The memory stick and the flash memory are accessed via the "File Manager". Accessing the File System The instrument also supports two standard methods to access the file system form a remote client: ● FTP (file transfer protocol) ● File sharing according to the SAMBA/SMB (server message block) protocol. Both methods allow the access to the folder /var/user/share. Default password The FTP and SAMBA/SMB file access use the user "instrument" with the default pass- word "instrument". It is highly recommenced that you change this password in the Chapter 5.2.3.15, "Security", on page 99 dialog before connecting the instrument to the network! Refer also to Application Note 1GP72 "Connectivity of Signal Generators", provided on the Rohde & Schwarz website, at http://www.rohde-schwarz.com/appnotes. Linux Operating System

Use the "Setup > Display Settings" dialog to switch on or off the screen saver and to adjust the screen saver settings. 2.6 Setting Up a Network (LAN) Connection The R&S SMC is equipped with a network interface and can be connected to an Ether- net LAN (local area network). Provided the appropriate rights have been assigned by the network administrator and the Linux firewall configuration is adapted accordingly, the interface can be used, for example: ● To transfer data between a controller and the instrument, e.g. in order to run a remote control program. See Chapter 6, "Remote Control Basics", on page 190. ● To access or control the measurement from a remote computer using the R&S VISA or Ultr@VNC programs (or similar tools, like another VNC client or any Web browser supporting Java) ● To transfer data from a remote computer and back, e.g. using network folders This section describes how to configure the LAN interface. It includes the following top- ics: ● Chapter 2.6.1, "Connecting the Instrument to the Network", on page 34 ● Chapter 2.6.2, "Assigning the IP Address", on page 35 Accessing Operating System No access to the operating system is required for normal operation. All necessary system settings can be made in the "Setup" dialog. 2.6.1 Connecting the Instrument to the Network There are two methods to establish a LAN connection to the instrument: ● A non-dedicated network (Ethernet) connection from the instrument to an existing network ● A dedicated network connection (Point-to-point connection) between the instru- ment and a single computer In both cases, an IP address has to be assigned to the instrument and the computer, which is usually accomplished automatically. See also Chapter 2.6.2, "Assigning the IP Address", on page 35. Setting Up a Network (LAN) Connection

R&S®SMC100A 35 Operating Manual 1411.4060.32 ─ 09 To set up a network (LAN) connection Risk of network failure Before connecting the instrument to the network or configuring the network, consult your network administrator. Errors may affect the entire network. ► Connect the instrument to the network or to a single PC. If the instrument is connected to the LAN, the operating system automatically detects the network connection and activates the required drivers. By default, the instrument is configured to use dynamic TCP/IP configuration and obtain all address information automatically. The network card can be operated with a 10/100 Mbps Ethernet IEEE 802.3u interface. Risk of network connection failure Network cables and cable connectors of poor quality may cause network connection failures. If the network connection to the instrument fails, check the network infrastructure and contact your network administrator. For details, see section "Status Information, Error Messages and Troubleshooting". 2.6.2 Assigning the IP Address Depending on the network capacities, the TCP/IP address information for the instru- ment can be obtained in different ways. ● If the network supports dynamic TCP/IP configuration using the Dynamic Host Configuration Protocol (DHCP), all address information can be assigned automati- cally. ● If the network does not support DHCP, the instrument tries to obtain the IP address via Zeroconf (APIPA) protocol. If this attempt does not succeed or if the instrument is set to use alternate TCP/IP configuration, the addresses must be set manually. By default, the instrument is configured to use dynamic TCP/IP configuration and obtain all address information automatically. This means that it is safe to establish a physical connection to the LAN without any previous instrument configuration. Setting Up a Network (LAN) Connection

R&S®SMC100A 36 Operating Manual 1411.4060.32 ─ 09 Risk of network errors! Connection errors can affect the entire network. If your network does not support DHCP, or if you choose to disable dynamic TCP/IP configuration, you must assign valid address information before connecting the instru- ment to the LAN. Contact your network administrator to obtain a valid IP address. Assigning the IP address on the instrument 1. Press the SETUP key and select the "Network Settings" dialog. 2. Set the "Address Mode" to Static. 3. Select the "IP Address" and enter the IP address, for example 192.168.0.1.. The IP address consists of four number blocks separated by dots. Every block con- tains 3 numbers in maximum. 4. Select the "Subnet Mask" and enter the subnet mask, for example 255.255.255.0. The subnet mask consists of four number blocks separated by dots. Every block contains 3 numbers in maximum. Use computer names to identify the instrument In networks using a DHCP server, it is recommended that you address the instrument by its unambiguous computer name, see Chapter 2.6.3, "Using Computer Names", on page 36. A computer name (hostname) is an unique dedicated identification of the instrument, that remains permanent as long as it is not explicitly changed. Hence, you can address an instrument by the same identification (computer name), irrespectively if a network or a point-to-point connection is used. To assign the IP address manually on the remote computer ► Obtain the necessary information from your network administrator. If you use more than one LAN connector, you need separate address information for each connec- tor. For information on how to perform the configurations, refer to the documentation of the operating system the remote computer uses. 2.6.3 Using Computer Names In a LAN that uses a DNS server (Domain Name System server), each PC or instru- ment connected in the LAN can be accessed via an unambiguous computer name instead of the IP address. The DNS server translates the host name to the IP address. This is especially useful when a DHCP server is used, as a new IP address may be assigned each time the instrument is restarted. Setting Up a Network (LAN) Connection

R&S®SMC100A 37 Operating Manual 1411.4060.32 ─ 09 Each instrument is delivered with an assigned computer name, but this name can be changed.

This allows convenient operation of the instrument from the desktop although the instrument is integrated in a rack somewhere else. For an overview of the instrument's operating concept and the different ways to control and operate the instrument, see Chapter 3.1, "Brief Introduction to the Instrument's Concept", on page 45. There are different ways to establish a remote access connection to the signal genera- tor but all of them require an established LAN connection between the instrument and the remote computer. The simplest way to remote access the instrument is to use a Web browser, such as Windows Internet Explorer or Mozilla Firefox for instance. Alter- natively a remote access via a special application can be used. For example, the free-of-charge program Ultr@VNC for PCs with Linux/Unix or Win- dows operating system is available for setting up the remote access connection. Using this application requires additional installation. See the following table for an overview of the different ways to establish a remote access connection to the signal generator.

3 Getting Started This section helps you to get familiar with the R&S SMC. It provides an introduction to the general concept of the instrument with a sample of the possible application fields, and a description of the main blocks in the signal generation flow. This section also explains the operating concept in general and includes a brief intro- duction to operation by a step-by-step description of the configuration. The example is intended to provide a quick overview of the settings provided. No additional equipment is required. 3.1 Brief Introduction to the Instrument's Concept The operating concept of the R&S SMC employs the following three ways of instru- ment control: ● Manual operation ● Remote control ● Remote access Manual Operation The R&S SMC can be entirely operated from the front panel. Peripherals such as mouse or keyboard can be connected but are not essential. The R&S SMC is equipped with an intuitive user interface. The central element of the display is the block diagram that shows the signal flow and processing from the left on the display to most right, i.e. the generated signal can be seen at a glance. Each block represents a functional unit of the instrument. Thus you always know the position at which a parameter affects the signal flow. The main settings of a block are indicated in the block. The interconnection of employed inputs and outputs is also shown. The user is thus always informed about the connection of inputs and outputs in the signal flow and where they can be configured. A window is opened for each menu where parameters can be set. When the window is opened, an entry is made in the "Winbar" below the display. All open menus are of equal priority (not modal) and can be accessed any time. The block diagram in the figure below shows a fully equipped instrument. Brief Introduction to the Instrument's Concept

Figure 3-1: Block diagram of a fully equipped R&S SMC With the rotary knob, you can navigate in the block diagram and the dialogs, and oper- ate the instrument with one hand. The cursor is moved line by line through the block diagram or dialog. Turning the button clockwise advances the cursor. The selected block can be activated or deactivated with the TOGGLE key. Active blocks are high- lighted by a colored background. The instrument comprises a comprehensive info and help system. You can access the context-sensitive help with the HELP (F1) key at any time. The help system indicates the currently selected parameter and offers additional services such as cross referen- ces, index and contents. The content of the help system corresponds to the operating manual of the instrument. Warning and conflict messages caused by incorrect operation as well as further infor- mation are displayed in the "Info" line. A complete list of existing conflicts is displayed when the INFO (CTRL+I) key is pressed. Additional information on entries can be requested from the help system. The history function permits display of all messages. Assistants simplify the completion of tables. After data entry in the assistant, the table is modified only after the "Accept" button has been pressed. Pressing the "Accept" but- ton also stores the assistant data. For an introduction into the manual operating of the instrument, detailed operating instructions and an overview of menus refer to Chapter 4, "Manual Operation", on page 54. For an in-depth description of the dialog boxes and the instrument functions, refer to section Chapter 5.1, "Overview of Instrument Functions", on page 78. Remote Control Remote control is an operation of the instrument by means of remote control com- mands or programs that automatize repeating settings. The instrument is connected to a computer running the program. The R&S SMC supports various remote control connections: ● Connecting the instrument to a (LAN) network ● Connecting a PC via the IEC-bus (IEEE 488) interface ● Remote control via the USB interface Brief Introduction to the Instrument's Concept

Tip: For remote control over LAN or USB, you can use the R&S VISA (Virtual Instru- ment Software Architecture) library provided for download at the Rohde & Schwarz website http://www.rohde-schwarz.com/rsvisa. This way of operation and the instructions how to set up a connection for remote con- trol are described in the Chapter 6, "Remote Control Basics", on page 190. The description of the remote control commands is provided in Chapter 7, "Remote Control Commands", on page 233. Remote access Remote access is the operating of the instrument from a remote computer. Both the R&S SMC and the computer are connected in a LAN. Remote access in contrast to remote control does not use remote-control commands but a separate software which is installed on the remote computer. After its start, the software simulates the user interface of the instrument. The instrument can thus be operated from the remote computer as on the unit itself. The individual functions are operated using the mouse and keyboard. Specific instrument functions can be execu- ted using specific key combinations on the keyboard or a front panel key emulation that can be operated with the mouse. This way of operation and the instructions how to set up a connection for remote access are described in Chapter 2.7, "Remote Access via an External Controller", on page 37. 3.2 Application Field of the Instrument The Signal Generator R&S SMC is suitable for applications which require sine wave signals with high spectral purity, i.e. signals with high quality. The internal LF generator is used as a modulation source and permits generation of analog modulated signals. A signal can be amplitude (AM), frequency (FM), phase (PhiM) or pulse (PM) modulated. With its adjustable frequency range from 9 kHz up to 3.2 GHz the generator is espe- cially designed for medium scale RF generation. Various fields of applications are cov- ered, e.g. in lab, service, production and quality assurance. ● generating modulated signals to check the data taken by a receiver ● functionality testing of components in production ● generation of modulated signals which are required in mobile radio ● signal generation and modulation for EMC measurements of components ● test equipment for service and maintenance ● applications in research and apprenticeship, e.g at universities ● high signal quality ● internal analog modulation modes: AM, FM, PhiM ● pulse modulation ● frequency and level sweep Application Field of the Instrument

● remote control via USB, LAN and IEC Bus Note: For faster operation by remote control the instrument can be equipped with an IEC bus interface (option R&S SMC-K4). 3.3 Description of Individual Diagram Blocks The signal path of the instrument is configured by installing a frequency option that comprises all required modules. One of the following options must be installed. ● R&S SMC-B101 (up to 1.1 GHz) ● R&S SMC-B103 (up to 3.2 GHz) ● R&S SMC-B131 (up to 31,8 GHz) See data sheet for detailed information. Up-to-date information is available at R&S SMC homepage on the internet http:// www.rohde-schwarz.com/product/smc100a.html. Mod Gen block The internal modulation sources are configured in this block. Also, the "LF frequency sweep" can be activated here. An internal LF generator is available as the internal source for the analog modulations AM, FM and PHiM. The used modulation shape is a sine wave signal. The internal modulation signals are provided at the LF output at the front of the instru- ment. The LF output signal and the modulations sources for the analog modulations AM, FM and PhiM can be selected independently from each other. A pulse generator provides single and double pulse modulation with selectable pulse widths and periods. The internal pulse generator signal is provided at the PULSE VIDEO output at the rear of the instrument. The R&S SMC offers three different sweep types (frequency sweep, level sweep and LF sweep) to be activated alternatively. Each type has 6 modes which differ with respect to the sweep cycle mode (continuous, individual and step-by-step) and trigger- ing mode (automatic, internal and external). In the "Mod Gen" block, the LF sweep is configured. Frequency and level sweep settings are accessed via the "RF" block. The status display in the block shows whether LF generator and/or a sweep are active. The selected internal LF generator and/or noise source are switched on or off with the TOGGLE ON/OFF key. Modulation block The internal and external analog modulations are configured and activated in this block. The MOD ON/OFF key switches the active modulation(s) on/off. Description of Individual Diagram Blocks

The internal modulation sources are configured in the "Mod Gen" block. External amplitude, frequency or phase modulation signals can be fed in at the input connector MOD EXT at the front of the instrument. An external pulse signal is fed in via the BNC connector PULSE EXT at the rear of the instrument. AC or DC coupling for external feed is possible. Available internal and external analog modulation modes are: ● Amplitude modulation (AM) ● Frequency modulation (FM) ● Phase modulation (PhiM) ● Pulse modulation (Pulse) Note: For modulation modes that can be simultaneously used, refer to the R&S SMC data sheet. The status display in the block shows the active modulation(s). Use the TOGGLE ON/OFF key to switch the active modulation of the block on or off. RF block In this block, the RF parameters and frequency/level sweep settings are set. The active sweep is displayed in the block. The RF ON/OFF key switches the RF sig- nal on and off. When the signal is switched off, the switch before the RF output symbol is open. RF settings include: ● Frequency and reference frequency ● Level settings; if required. ● NRP-Z Power Viewer using power sensors ● Frequency and level sweep The RF 50 OHM output connector at the front of the instrument provides the RF signal. An external trigger/gate signal for sweeps is input via the INST TRIG connector at the rear of the instrument Note: Frequency and level are set fast with the aid of the FREQ and LEVEL keys. Use the TOGGLE ON/OFF key to switch the RF output on or off. 3.4 Example of Setup This section provides an example on how to configure the instrument for generating of an amplitude modulated signal.

Turn the rotary knob to select the "Execute Single Sweep" button. Press the rotary knob to trigger (start) the frequency sweep. A linear single sweep signal is now present at the RF output, starting at 100 MHz. The sweep is processed in 1 MHz steps with dwell time of 10 ms per step up to the stop frequency of 500 MHz. The sweep starts at 100 MHz, stops at 500 MHz in 1 MHz steps is output with a dwell time of 10 ms per step. Example of Setup

4 Manual Operation The R&S SMC can be operated intuitively either via the interactive block diagram or via a menu tree. All menus are in the form of windows that can be operated in the same way. Rotary knob, keys and softkeys, or alternatively a mouse, allow direct and there- fore convenient access to entries and settings. The clear-cut display shows the current signal generator state. Numerous help func- tions support the user in signal configuration. This section describes the concept of manual operation of the signal generator. This includes a description of the general structure of a dialog box, working with dialog boxes and the block diagram and the setting of parameters. For an in-depth description of the dialog boxes and the instrument functions refer to section "Instrument Functions". 4.1 Key Features The manual operating concept of the R&S SMC enables the user to make settings as intuitively as possible and at the same time gives a permanent overview of characteris- tics of the generated signal and of the current instrument state. Numerous online help functions support user settings. Block diagram The block diagram is the core of the operating concept. A graphics display shows the current configuration and the signal flow in the form of a block diagram. All graphical elements can be accessed for operation. An element is selected by means of the arrow keys and the associated setting function is called by pressing Enter. Required menus and graphs are displayed on the block diagram which is displayed again in the foreground whenever the DIAGRAM (CTRL+D) key is pressed. Permanent frequency and level display The main characteristics of the RF signal, frequency and level, are permanently dis- played in the header section of the screen and can be directly set in the display fields after the FREQ (CTRL+F) or LEVEL (CTRL+L) key is pressed. Status messages for the output signal are displayed in addition to frequency and level. Operation via Graphical User Interface ● Functional blocks Menus are assigned to the specific function blocks in the block diagram. The func- tion blocks represent elements of signal generation. Function blocks displayed with Key Features

a blue frame can be directly switched on and off by means of the TOGGLE ON/OFF (CTRL+T) key. The menus of the highlighted function blocks can be called by pressing the ENTER key. – Example: The "Modulation" block contains all menus required for modulation signal con- figuration. In this block all modulations can be selected. ● Signal flow The signal flow between the function blocks and the employed inputs and outputs are also shown. ● Menu tree The menu tree can be opened and closed with the MENU (CTRL+M) key. The menu tree is organized in the same way as the directories under Windows. The function blocks correspond to the first directory level, the menus to subdirectories. Operation corresponds to the Windows concept To offer the user a familiar environment, operation is very similar to operation of Win- dows user interfaces. All menus and tables are made up of known elements, such as selection lists, check boxes and entry fields. A blue frame indicates that the selected item is active. In the highlighted element, entries can be made. Rotary knob Operation is possible via front-panel keys, an external keyboard and the mouse. How- ever, most of the settings can be easily made with the rotary knob: ● Turning the rotary knob shifts the entry focus to the target element. Key Features

● Pressing the rotary knob activates the selected entry field. Depending on the parameter, the submenu is called, the numeric value varied, the list entry selected or the check box activated or deactivated. ● If a value is entered, the entry is stored by another click on the rotary knob and the editing mode is exited. Clear settings with the aid of independent subdialogs A separate window is opened for each dialog and subdialog. The dialogs can be oper- ated independently of each other, i.e. none of the dialogs requires that settings in other dialogs be completed before it can be closed. This ensures flexible operation at all times. Keys with assigned simple functions Most keys on the front panel of the R&S SMC directly perform a simple function. Since a great number of settings can thus be made by a keystroke, operation is easy. For instance, the CLOSE (ESC) key closes the active menu; with the RF ON/OFF (CTRL+R) key the RF output signal can be switched on or off. An exception are keys that call a menu such as the MENU (CTRL+M) key which opens the complete menu tree of the instrument, the SETUP (CTRL+E) key which opens the menus for general instrument settings or the FILE (CTRL+S) key which opens the menu for file management. Help functions for user support Numerous help functions support the user in signal configuration. ● Value ranges The valid setting range is displayed for each numeric parameter. This requires a short wait after activation of the entry field. The range is then displayed automati- cally after a few seconds. If the entered value is outside the permissible range, the next permissible value is automatically set and a message is output. ● Context-sensitive help Context-sensitive help for each parameter can be called with the HELP or F1 key. ● Comprehensive online help Each help page is part of a comprehensive online help function which can be called by means of an index, a content tree or the "Previous/Next" buttons. Info line with messages for indication of the current instrument state A great variety of different messages such as status messages, error messages, warn- ings or information are displayed in the header field of the screen. With the aid of the INFO (CTRL+I) key, help pages can be called for most of the messages. They provide Key Features

background information on the message and indicate operating steps that may be required. All messages are explained in the online help which can be called with the HELP (F1) key. 4.2 Display The display shows the current signal generator state and offers graphical elements for direct operation. It is divided into three sections: ● The frequency and level display with info line indicates the main output signal parameters and reports the current state with status, error and warning messages. ● The block diagram shows the instrument configuration, the signal characteristic as well as the inputs and outputs used and permits interactive operation via graphics elements. Active menus and graphs are displayed on top of the block diagram. ● Winbar with labeled softkeys for menu display. The block diagram in the figure below shows a fully equipped instrument. Figure 4-1: Block diagram of a fully equipped R&S SMC The R&S SMC supports a multi language user interface, that can be set in the "Setup > Display Settings" dialog, see "GUI Language" on page 94. 4.2.1 Settings Displayed in the Header Section Frequency/level settings and a few status messages (see Chapter 4.2.2, "Status Infor- mation and Messages", on page 58) are displayed in the header field of the screen. The display may vary depending on the instrument's operating mode: ● In the sweep mode, the current frequency or level of the output signal is displayed. The status message "SweepMode" is displayed in the info line. ● If user correction is active, the status message "UCorr" is displayed in the info line. Display

The values displayed in the "Freq" and "Level" fields include a set offset or multiplier factor. For more See alos Chapter 5.3.2, "RF Frequency", on page 121 and Chapter 5.3.5.1, "Overview of RF Level", on page 128. The frequency and level indication can be enlarged so that it covers the complete dis- play of the R&S SMC by using the DIAGR key. This key toggles between block dia- gram, magnified frequency and level indication and the display of the active dialog. This requires the "Summary Screen Toggle" to be enabled. See also "Toggle Summary Screen" on page 94. 4.2.2 Status Information and Messages The instrument indicates status information and messages in the header section of the screen. The messages differ with respect to their importance like errors, warnings or information and require different treatment. For additional information refer to the info window (see Chapter 4.2.3, "Info Window", on page 59). Refer to Chapter 9, "Status Information, Error Messages and Troubleshooting", on page 372 for an overview of all status information and messages and corrective actions. 4.2.2.1 Status Information The status information gives the user an overview of the main operating states and set- tings of the instrument. The states are indicated for information only and do not neces- sitate any action by the user. Status information is displayed between the frequency and level fields, at the left of the info line or in the info line itself. 4.2.2.2 Messages Messages indicate errors in the instrument. They are displayed in the info line in differ- ent colors depending on their importance and display duration. Errors (e.g. no calibra- tion data) are displayed in red, information (e.g. file not found) and warnings in black. Warnings indicate less significant errors (e.g. the instrument operates outside specified data). 4.2.2.3 Volatile messages Brief messages report automatic settings in the instrument (e.g. switching off of incom- patible types of modulation) or on illegal entries that are not accepted by the instrument (e.g. range violations). They are displayed in the info line on a yellow background. They are displayed on top of status information or permanent messages. Display

Volatile messages do not normally demand user actions and disappear automatically after a brief period of time. They are stored in the history, however. These messages can be read from remote using the commands :SYSTem:ERRor[: NEXT]? and :SYSTem:ERRor:ALL?. 4.2.2.4 Permanent Messages Permanent messages are displayed if an error occurs that impairs further instrument operation, e.g. a hardware fault. The error signalled by a permanent message must be eliminated before correct instrument operation can be ensured. The message is displayed until the error is eliminated. It covers the status display in the info line. After error elimination, the message automatically disappears and is also recorded in the history. These messages can be read from remote using the command :SYSTem:SERRor?. 4.2.3 Info Window A few operating states and the current message are displayed in the info line. The INFO window with a list of current permanent messages and a detailed description of each message can be opened with the INFO (CTRL+I) key. The upper section of the info window contains a list of all current permanent messages in the order of their occurrence, i.e. the most recent message is displayed first. In the lower section of the window, additional information on the highlighted message is dis- played. A history of all messages that have occurred since instrument switch-on can be called with the "History" key. The most recent message is displayed first. The messages are color-coded according to their level. Device-specific messages are red, info and remote control error are black. The level is also indicated in the "Lev" column (Err, Sys or Info). Column "SCPI" indicates the SCPI error code. With the aid of the softkey buttons, error messages can be cleared and a history of all messages called. Delete Clears the highlighted message. This button is available only if the history of the messages is displayed. Display

Delete All Clears all messages. This button is available only if the history of the messages is displayed. History Calls the list of all messages that have occurred since instrument switch-on. The most recent messages are displayed at the top of the list. When the button is pressed again, the list of current messages is displayed. Remote command: :SYSTem:ERRor[:NEXT]? on page 349 or :STATus:QUEue[:NEXT]? on page 346 Each time a SYST:ERR? or STAT:QUE? query is sent, the oldest entry in the error queue is returned and at the same time cleared in the list. 4.2.4 Block Diagram The block diagram shows provided options, signal configuration and the currently selected signal flow of the generator with inputs and outputs used. Signal generation can be completely operated from the block diagram. The highlighted function block can be directly switched on and off with the TOGGLE ON/OFF (CTRL+T) key. Pressing the Enter opens the associated setting menu. Figure 4-2: Block diagram of the R&S SMC 4.2.4.1 Function Blocks in the Block Diagram Each block represents a function of signal generation. The function is indicated in the headline of the block. In the check box, the respective function can be quickly activa- ted/ deactivated with the TOGGLE ON/OFF (CTRL+T) key. After activation, the block is displayed in blue. Status information is displayed below the check box. It is different for the different blocks. Pressing the rotary knob (front panel) or the "Config..." button (mouse) opens the asso- ciated setting menu. Display

Example: Modulation block In this block, the modulation signals are set. The status information of the "Modulation" block indicates the selected modulation. 4.2.4.2 Signal Flow and Input/Output Symbols in the Block Diagram The input/output symbols in the block diagram show the currently used inputs and out- puts of the signal generator. Unused inputs and outputs are not shown. The lines indi- cate the signal flow. Symbols and labels refer to the corresponding inputs and outputs on the front and rear panel of the signal generator. The direction - input or output - is indicated by an arrow. Example: The symbols indicate the input for the external pulse signal on the instrument rear panel. 4.2.5 Structure of the Dialogs The parameters are set in the menus. Menus are accessed either via the function blocks in the diagram or by means of the MENU (CTRL+M) key. The menus are dis- played on top of the block diagram. The WINBAR key toggles between the active menus. The REARR key toggles between the enlarged and normal sized menus. Working with menus and dialog boxes is described in Chapter 4.3, "Accessing Dia- logs", on page 62; the setting of parameters in Chapter 4.4, "Setting Parameters", on page 63. The menus are in Windows format. The menus differ in details depending on their function but they consist of the same main elements. Each menu consists of a menu header and one or more menu areas with various fields for setting parameters. The header line contains the name of the menu and the buttons for minimizing and closing the menu. To operate the buttons, use the mouse or the front key CLOSE (ESC). Display

Several fields of associated but separately set parameters are organized in menu areas. A menu area is framed and labelled with the function common to all parameters. Example: Pulse Generator Each of the setting fields is assigned a parameter name. The kind of setting varies depending on the parameter to be set. Some settings can only be made in a specific configuration. If setting is not permitted with the specific configuration selected, the respective item is disabled and displayed in gray and the entry or selection field cannot be accessed. 4.3 Accessing Dialogs The MENU (CTRL+M) key opens the complete menu tree. Selecting a functional block and pressing the ENTER key opens the menu associated with this block. An alternatively way to access a dialog is to use the CLOSE (ESC), DIAGRAM (CTRL +D) and REARR (CTRL+A) keys on the front panel. For a quick access to the dialogs, use one of the following alternative methods. Displaying the block diagram or a dialog in the foreground ► Press the DIAGRAM (CTRL+D) key to move the cursor to the block diagram. All active menus are minimized. Enlarging the indication of the header section ► Press the DIAGRAM key twice to enlarge the indication of the header section. Tip: Use the REARR key to toggle between the enlarged and normal sized dialogs. Accessing the menu tree ► Press the MENU (CTRL+M) key to open the complete menu tree. Calling the File or Setup dialog ► Use the SETUP (CTRL+E) key to open the "Menu Tree" or "Setup" dialog, and (CTRL+S) to open the "File" dialog. Closing an active menu ► Press the CLOSE key to close an active menu. Tip: If the cursor is at the highest menu level, you can also use the ESC key to close the active menu. Accessing Dialogs

Accessing the header area ► Press the FREQ (CTRL+F) and LEVEL (CTRL+L) keys to activate the "Frequency" or "Level" entry fields in the header area. Keyboard Shortcuts Keyboard shortcuts (e.g. "Ctrl + D" for the displaying the block diagram in the fore- ground) provide direct access to all utility dialogs of the instrument (see Chapter 4.8, "Legend of Front-Panel Controls", on page 76). 4.4 Setting Parameters The R&S SMC offers several and sometimes alternative possibilities for setting param- eters. Operation is possible from the front panel, with the aid of a mouse and/or from a PC keyboard. The examples whitin this description focus on the operation from the front panel. For more information, refer to: ● Chapter 4.8, "Legend of Front-Panel Controls", on page 76 for an overview of key functions and a cross-reference between the front panel keys and the keyboard shortcuts ● section "Instrument Functions" for a detailed description of key functions. Most of the parameters are set in the different menus. The R&S SMC provides alterna- tive ways for accessing the dialogs. Turn the rotary knob and navigate to the corre- sponding block in the block diagram and press the knob to open the dialog or perform a mouse click on the "Config..." button. These menus can only be called with the SETUP (CTRL+E) and (CTRL+S) keys. Frequency and level are directly set in the header area of the display using the FREQ and LEVEL keys. Specific settings can also be made directly in the block diagram, e.g. activating a func- tion block by means of the TOGGLE ON/OFF (CTRL+T) key or switching the RF out- put on and off with the aid of the RF ON/OFF (CTRL+R) key. Changes affecting the signal flow are immediately visible in the graphics display. This section provides an information about the parameter handling that comprises of the following main steps: ● Chapter 4.4.1, "Working with the Cursor", on page 64 ● Chapter 4.4.2, "Selecting a Control Element", on page 64 ● Chapter 4.4.3, "Switching Parameters On/Off", on page 65 Setting Parameters

Terminating the entry of a numeric value To terminate the entry of a numeric value: 1. Press the rotary knob (= Enter). 2. Press a UNIT key on the front panel. 3. Select a "Unit" in the selection field next to the parameter value. 4.4.5 Working with Units The unit of a parameter is displayed next to the value. When the parameter is edited, the unit is selected either from the list or by means of the front-panel keys. When the entry is completed, the unit can be changed. In this case the value remains unchanged but is automatically adapted to the new unit. Setting Parameters

While operating the instrument by means of a mouse, assign the unit to the selected parameter before entering its value. Assigning a unit To assign a unit to a value, use one of the following alternatives: 1. Press a UNIT key on the front panel. 2. Select a "Unit" in the selection field next to the parameter value. Press the ENTER key. The unit displayed in the entry field next to the value is assigned. Changing a unit To subsequently change a unit, i.e. after the entry has been terminated and when the editing mode is not active, use one of the following alternatives: 1. Press a UNIT key on the front panel. 2. Select"Unit" in the selection field next to the parameter value. The value remains unchanged but the display is automatically adapted to the new unit, i.e. the value is recalculated to suit the new unit. The new unit is indicated in the value field of the menu. 4.4.6 Selecting a Value from a List Selection lists provide a list of predefined values for the selected parameter. To select a item from a list, proceed as follow: 1. Press ENTER key to open the list. 2. Use one of the following alternatives to navigate through the list: a) Turn the rotary knob or use the UP/DOWN arrow keys. The selected item is highlighted. b) Press TOGGLE ON/OFF key several times until the preferred entry is dis- played in the selection field. Setting Parameters

3. To confirm the selection, press the ENTER key. 4.4.7 Terminating Entries with Confirmation The instrument behaves different by the termination of entries deppending on the parameter type and the way this parameter is set. Confirming settings ► To confirm the settings, press the rotary knob or one of the UNIT keys (see also Chapter 4.4.5, "Working with Units ", on page 66) . Note: Variations by means of the rotary knob are immediately set. Confirming multiple values In some cases, like for instance when editing data in a user correction table, it is useful first to enter few values and to confirm them together. Such settings require additional confirmation. Not yet confirmed settings are displayed on a yellow background as an indication that the currently displayed values do not represent the target signal. ► To confirm these settings, select the "Save" or "Accept" button, respectively. Confirming parameters with On/Off state Most of the instrument functions with enabled and disabled states are calculated and effective only after this functions have been enabled. However, there are functions like the frequency variation of the reference oscillator for instance, that are immediately set after confirmation. ► To confirm a parameter with On/Off state, enable the parameter. 4.4.8 Restoring the Previous Value Parameter variations with the rotary knob are immediately set and therefore not rever- sible. Normally, values cannot be restored in the case of mouse control because no explicit confirmation is required in this case and entries are automatically confirmed when the entry or selection field is exited. Restoring values In the case of front-panel control or operation from the keyboard, previous values can be restored as long as the new value is not confirmed, i.e. the entry is not completed. ► To restore the values, press the ESC key. Setting Parameters

Restoring values that require confirmation All settings that are not confirmed with the "Accept" button but require this additional confirmation can be restored. 1. Press the ESC key. A confirmation query is displayed. 2. Confirm with "OK" to abort the changes. Select "Cancel" to return to the dialog. The previous selected settings are dis- played. Restoring values after an extended calculation has been started Calculation and setting might require different period of time. Many settings are made without noticeable calculation times; such operations are indicated by a "BUSY" mes- sage displayed in the status field of the header section. A window with a progress indicates that the instrument performs an extended calcula- tion that requires longer calculation time. The termination of such a calculation restores the previous values. ► Press the ABORT button to terminate the calculation. All previous values are restored. 4.5 Editors The R&S SMC provides a user-friendly editor for defining frequency and level value pairs, that are used for user-defined level correction (UCOR). The data is edited in a list editor, as described in Working with List Editor . The lists are saved to files and may thus have any length. The file name of the lists and the directory to which the files are saved are user-selectable. The file prefix is different for each list type and is permanently assigned by the system. For information about file handling and overview of the automatically assigned file pre- fixes, refer to Chapter 4.7, "File Management", on page 72. 4.5.1 Working with List Editor The "List Editor" contains a table for entering user-defined frequency and level value pairs. You can access the editor from the "User Correction" dialog. User correction is used to increase the level accuracy of the RF output signal by means of user-defined level correction values. Editors

Editing list mode data lists 1. To access a list editor and open an existing data list for editing, use the cursor keys to select the associated button "Edit User Correction Data..." or "Edit List Mode Data..." (if available) in the individual menu. The selected list is displayed and the cursor marks the first row of the "Frequency/Hz" column. If no list has been selected, a blank list of only one row is displayed. 2. Press the LEFT/RIGHT arrow keys to change between the colums. Use the UP/DOWN arrow keys to mark a row. 3. Use the numeric keys to enter the value for the value pairs in the "Frequency/Hz" and "Power/dBm" table columns. A blank row is inserted at the end of the list. Terminate the entry by pressing a UNIT key. 4. To select a row, select the "GoTo" button and press the ENTER key. Use the numeric keys to enter the row index in the entry field and press the ENTER key to confirm the entry. The cursor moves to the selected row. 5. To insert a new row in the table, select the row above which the new row is to be inserted and select "Insert Row(s)". A row is inserted above the currently marked row. If no row has been selected, a row is inserted at the beginning of the list. 6. Use the "Save" function to save the edited list under its current name. Enter the file name in the "File Select" dialog and select the directory (see Chap- ter 4.7.1, "File Select Dialog", on page 73). Only complete value pairs are taken into consideration; rows containing an entry in only one column are ignored. Creating a new list mode data list A new list can be created under a new name either by generating a blank file in the "File Select" menu (see section Chapter 4.7, "File Management", on page 72) or by changing an existing list which will then be saved under a new name. 1. To create an empty data list, select "RF > User Correction > User Cor. Data... > New User Correction Data" and enter the file name of the new data list. Editors

2. To open the data list for editing, select the associated button "Edit User Correction Data...". Edit the list and save it under a new name. 4.6 How to Use the Help System The R&S SMC is equipped with a context-sensitive help function. A help page is avail- able for each parameter and can be called any time during instrument operation. Calling context-sensitive and general help ► To display the general help dialog box, press the HELP (F1) key. The help dialog is displayed. A topic containing information about the current menu or the currently opened dialog box and its function is displayed. On top, the help dialog box contains a navigation bar with: ● "Contents" - accesses a table of help contents ● "Index" - switches to an index table ● "Back "/"Previous"/"Next" for navigation to further help topics Navigating in the table of contents 1. To navigate within the table of contents entries, use the UP/DOWN keys. Entries that contain further entries are marked with a plus sign. 2. To display a help topic, press the "ENTER" key. The corresponding help topic is displayed. Navigating in the help topics 1. To scroll through a page, use the UP/DOWN arrow keys. 2. To follow a cross-reference, select the link text. 3. To return to the previous page, select "Back". This function scrolls back all steps that you have performed before. How to Use the Help System

4. Use the "Scroll Right" or "Scroll Left" buttons to shift the indicated area of the navi- gation window to the left or right. Using the Index 1. Select "Index". 2. Enter the first characters of the topic you are interested in. The entries starting with these characters are displayed. 3. Press the ENTER key to change the focus. 4. Use the UP/DOWN keys to navigate and select the suitable keyword. 5. Press the ENTER key to display the help topic. The corresponding help topic is displayed. Closing the help window ► Press the HELP (F1) key. 4.7 File Management The R&S SMC uses files to save all instrument data, i.e. system and user data. The user data includes saved instrument settings and lists and the user correction. The files are stored in the internal memory of the instrument or on a USB memory stick. The /var directory can be used to save user-defined data; any subdirectory structure can be created on /var. Some default subdirectories are predefined, but can be changed at any time. The /opt directory is a protected system drive and therefore unaccessible system directory. The files on this directory contain data that must not be changed. Therefore, this drive should not be accessed, since reconstruction of the system partition will lead to data loss. To prevent inadvertent deletion or overwriting of system files, this drive is not specified in the file menus. Files can be exchanged either via a memory stick or a connected network. A memory stick is connected to the USB interface and is assigned the var/usb/ drive. In the case of a connected network, all network drives that can be accessed are available. The files are accessed in a "Save/Recall" dialog in the individual menus. The files are differentiated according to their extensions; each type of file is assigned a specific file content. The extension is usually of no consequence to the user since access to the files occurs in the individual menus where only the relevant type of file is available. See Chapter 4.7.2.1, "Extensions for User Files", on page 75 for an over- view of the supported file extensions. The user data can be roughly divided into the following data types: ● Settings File Management

Instrument settings can be saved and loaded. In case of saveing, the current set- ting is saved to the specified file. ● Lists Lists, e.g. user correction lists, can be loaded. They can be generated either exter- nally or internally. For internal generation, a new list must be created in the "File Select" dialog which will then be edited in the list editor of the individual menu. For more information, refer to: ● Chapter 4.8, "Legend of Front-Panel Controls", on page 76 for an overview of key functions and a cross-reference between the front panel keys and the keyboard shortcuts ● to section "Instrument Functions" for a detailed description of key functions. Accessing files with user data 1. To access an editable user data file, select the "Save/Recall" or "File Manger" func- tion in the individual dialog. 2. To access a loadable data file, select the "Select/New" or "File Manager" function in the individual dialog. 3. To access the "File Manager" function, press the SETUP (CTRL+E) key and select "Save/Recall > File Manager". A "File Select" window for loading, saving or creating a file or the "File Manager" dialog for managing all files is displayed. Saving and loading of all instrument settings All instrument settings are saved and loaded in the "File" menu. To access the "File" menu, press the FILE (CTRL+S) key. For more information, see Chapter 5.2.8, "Storing and Loading Instrument Data - File Key", on page 111. 4.7.1 File Select Dialog The "Save/Recall" dialaog displays the available drives and directories. In the upper part, "Recent Data Sets", the files last used are listed. File Management

The available drives and directories and the files of the selected directory are dis- played. The currently selected path is displayed above the window. Only the relevant files without file extensions are displayed. If the area is opened several times, the path last selected is displayed. When a file is saved or created, its name is user-selectable; the extension is assigned automatically and cannot be entered. The file is saved to the selected path. In addition to the files saved by the user, some menus also offer files containing prede- fined contents. These files are saved to a specific directory on system drive; for this reason, this directory cannot be chosen from the "File Select" menu. Working with the File Select dialog 1. Access the "File Select" dialog (see "Accessing files with user data" on page 73). 2. Navigate in the "File Select" dialog. 3. Load an existing file. In the "Recall Settings" dialog, mark a file and press the "Select" button. 4. Save a file. In the "Save Settings" dialog, enter file name in the "File Name:" field. Select the directory to which the file is to be saved and then select the "Save" but- ton. 5. Create a new file. To create a new file, use the "Save Settings" functionality, i.e. specify file name and directory and save the file. The created file is empty; it must be filled with the necessary values in the individ- ual editor. 4.7.2 File Manager The "File Manager" allows general file management such as copying, shifting, renam- ing and deleting files as well as generating new directories. File Management

Use the "File Type" to select a file type from the list. This can be used to process either all files (all files (*) selection) or a specific selection of files. See Chapter 4.7.2.1, "Extensions for User Files", on page 75 for an overview of the supported file exten- sions. The available drives and directories and the files of the selected directory are displayed. The currently selected path is displayed above the windows. If the area is opened several times, the path last selected is displayed. Unlike the "File Select" win- dow, the "File Manager" displays the full file names including extensions. Working with the File Manager dialog 1. Accessing the "File Manager" dialog (see "Accessing files with user data" on page 73). 2. Navigating in the "File Manager" dialog. Operation is very similar to the operation of a standard Windows explorer. 3. Moving, duplicating, deleting or renaming files To move a file, select the file and press the "Cut" button. Mark the directory to which the file is to be moved and select the "Paste" button. If the target directory already contains a file with the same name, a confirmation query is displayed to confirm overwriting of this file. Perform the similar steps and cut/copy/rename/delete the file. Tip: The operation corresponds to the Windows concept. 4. Creating a new directory Mark drive or directory level where the new directory is to be created, select the "Create New Directory" button and enter the name of the new directory in the entry window that opens. Confirm with ENTER. 4.7.2.1 Extensions for User Files The following table lists all available file extensions for user files. The currently availa- ble files on the instrument depend on the installed options. File Management

5 Instrument Function 5.1 Overview of Instrument Functions This chapter explains the functions of the R&S SMC and the options available in the setting menus. The associated SCPI command is specified for each parameter (where applicable). The description starts with the general instrument settings which do not directly affect signal generation. The majority of these settings can be accessed by means of front- panel softkey menus and not by means of function block menus. The signal generation functions are then described, beginning with the functions which affect the RF signal ("RF" block) and the analog modulations ("Mod" block). The config- uration of the modulation generators (LF generators and pulse generator) and of the LF sweep is offered in the "Mod Gen" block. The clock synthesis signal is set in the "Clock Synthesis" block. The general instrument settings include various functions, such as: ● Setting a defined basic setup using the PRESET key see Chapter 5.2.2, "Default Instrument Settings - Preset Key", on page 79 ● Switching from remote control to manual control using the LOCAL key see Chapter 5.2.4, "Switching to Manual Control - Local Key", on page 106 ● Configuring the generator and its interfaces in the "Setup" dialog - e.g. setting the GPIB address, starting an adjustment, querying instrument data see Chapter 5.2.3, "General Configuration of Instrument - Setup Key", on page 80 ● Calling up the online help using the HELP key see Chapter 5.2.7, "Help System - Help Key", on page 110 ● Querying messages using the INFO key see Chapter 5.2.6, "Messages - Info Key", on page 110 ● Loading and storing complete instrument settings in the "File" menu see Chapter 5.2.8, "Storing and Loading Instrument Data - File Key", on page 111 The RF signal and the reference oscillator are configured in the "RF" function block: ● CW mode see Chapter 5.3.1, "Overview of RF Signal", on page 120 ● Frequency and Level Sweep mode see Chapter 5.3.7.1, "Overview", on page 156 ● Reference Oscillator see Chapter 5.3.4, "Reference Oscillator", on page 126 ● RF Level see Chapter 5.3.5.1, "Overview of RF Level", on page 128 ● RF Level Sweep see Chapter 5.3.7.3, "RF Level Sweep", on page 164 Overview of Instrument Functions

● ALC see Chapter 5.3.5.4, "Automatic Level Control - ALC", on page 134 ● Power Sensors see Chapter 5.3.6.1, "NRP-Z Power Viewer", on page 148 ● User Correction see Chapter 5.3.5.6, "User Correction", on page 140 The analog and external digital modulations are activated in the "Modulation" function block: ● Amplitude Modulation see Chapter 5.4.2, "Amplitude Modulation (AM)", on page 171 ● Frequency Modulation see Chapter 5.4.3, "Frequency Modulation (FM)", on page 173 ● Phase Modulation see Chapter 5.4.4, "Phase Modulation (PhiM)", on page 175 ● Pulse Modulation see Chapter 5.4.5, "Pulse Modulation (PM)", on page 177 The internal LF generators, the LF frequency sweep and the pulse generator are con- figured in the "Mod Gen" function block: ● LF Frequency Sweep see Chapter 5.5.3, "LF Frequency Sweep", on page 180 ● LF output see Chapter 5.5.2, "LF Output", on page 179 5.2 General Instrument Settings 5.2.1 Overview of General Instrument Settings This section describes the settings which do not directly affect signal generation. Most of these settings can only be accessed by means of menus which are opened using keys or key combinations on the external keyboard or keys on the front panel key emu- lation. The general instrument settings therefore affect various functions, such as storing instrument settings using the FILE key or setting the GPIB address in the menu of the SETUP key. The order in which the descriptions are given corresponds to the layout of the keys on the front panel of the R&S SMC (from top left to bottom right). 5.2.2 Default Instrument Settings - Preset Key The PRESET key performs a defined instrument setup. All parameters and switching states are preset (also those of inactive operating modes). The default instrument set- tings provide a reproducible initial basis for further settings. General Instrument Settings

However, functions concerning the integration of the instrument in a measurement setup are not changed, for example the GPIB address or reference oscillator settings. When the instrument is switched on, it is not the preset state that is active, but rather the instrument state that was set before the instrument was switched on. User-defined instrument states can be accessed and stored in the "File" menu. Resetting the instrument to the factory state is possible with the Factory Preset func- tion. Preset Presets all parameters and switching states. The following list gives an overview of the presets for the most important generator set- tings. The other presets can be found in the preset tables of the individual menus and the information accompanying the remote commands. ● "RF frequency" = 1 GHz ● "RF level" RF output switched off ● "Offsets" = 0 ● "Modulations State" = Off ● Uninterrupted level settings are switched off "Level Attenuator Mode" = AUTO ● Internal level control "Level ALC" = AUTO ● User correction "Level Ucor" = OFF ● "LF output State" = Off ● "Sweep State" = Off Settings that are not affected by the PRESET key ● Reference frequency settings ("Ref Oscillator" menu) ● Power on settings ("Level/EMF" menu) ● Network settings ("Setup" menu) ● GPIB address ("Setup" menu) ● *IDN? Identification and emulation ("Setup" menu) ● Password and settings protected by passwords ("Setup" menu) ● Start/Stop Display Update ("Setup" menu) ● Display and keyboard settings ("Setup" menu) Remote command: *RST on page 236 5.2.3 General Configuration of Instrument - Setup Key The "Setup" menu provides access to basic instrument settings, regardless of the cur- rently set operating mode or measurement. It contains information on the insstrument's equipment, and comprises all settings for the general configuration of the instrument and its interfaces. To access the "Setup" menu, press the SETUP key. General Instrument Settings

The "Setup" menu is divided into functional sections as follows: ● "System": covers general instrument parameters. ● "Test": used to perform function tests. ● "Environment": used to configure the controller interfaces. ● "Remote": used to configure the remote control interfaces. ● "Protection": used to set the protection level for service functions and security set- tings. ● "Settings": used to save or recall instrument settings or to preset the instrument to factory settings. Most submenus of this key can be accessed only via the SETUP key or the menu tree ( MENU key), with the following exceptions: ● The "Reference Oscillator" dialog can also be accessed in the "RF" block and is therefore described in the section on this block (see Chapter 5.3.4, "Reference Oscillator", on page 126). 5.2.3.1 Internal Adjustments The R&S SMC is extremely accurate due to the integrated adjustment procedures, which you can execute directly on the instrument. Self-calibration routines that do require additional (external) measurement equipment are either described in the Service Manual of the instrument, or they require to be per- formed by a Rohde & Schwarz service center. Risk of invalid adjustment In order to achieve correct adjustment of the instrument, make sure that the instrument is warm before performing adjustments. The warm-up time is 30 minutes. When to perform adjustments? It is recommended to perform internal adjustments prior to any application that requires a maximum of level and frequency accuracy, especially when a long period of time has passed or if the ambient temperature of the instrument significantly differs from the one of the last adjustment. Additional Information to the Adjustments During adjustments, a progress indicator shows the status of the process. If any error occurs, the process aborts and an error message appears in the info line. The extent of the adjustments depends on the installed options. ► To access the settings for internal adjusmtents, press the SETUP key and select "System > Internal Adjustments". General Instrument Settings

In this dialog you can perform internal calibration routines. The remote commands required to define these settings are described in Chapter 7.4, "CALibration Subsystem", on page 240. Adjust All Performs all available internal calibration routines of the instrument. Remote command: :CALibration:ALL[:MEASure]? on page 240 Adjust Synthesis Performs all adjustments which affect the frequency. Remote command: :CALibration:FREQuency[:MEASure]? on page 240 Adjust Level Performs all adjustments which affect the level. The acquired correction values improve the settling time and the signal quality. Remote command: :CALibration:LEVel[:MEASure]? on page 241 5.2.3.2 Hardware Config In the "Hardware Config" dialog, the installed assemblies together with their variants and revision states can be displayed for servicing purposes. To open the "Hardware Config" dialog, select "System" and press the SETUP or MENU key. Section "Counter" in the upper part of the menu shows the "Operation Time" (in hours) and the number of power-on ("Power On Counter"). General Instrument Settings

The second part of the menu is a table that lists the installed assemblies. It is divided into the sections: ● "Common Assembly" ● "RF Assembly" Power On Count Displays the number of power-on. Remote command: :DIAGnostic:INFO:POCount? on page 243 Assembly The tables list the installed assemblies. "Assembly" Assembly name "Part Number" Part Number of assembly "Revision" Revision state of assembly Remote command: :DIAGnostic:BGINfo? on page 242 5.2.3.3 Software / Options The "Software/Options" dialog shows the firmware version of the instrument software and all installed hardware and software options. Software options purchased at a later stage can be activated with a keycode. The acti- vation code is supplied with the software option. How to install options is described in chapter 4 "Software Update / Installing Options" of the service manual. The installation of hardware options purchased at a later stage is also described in the service manual. Most hardware options need to be installed at an authorized Rohde&Schwarz service shop. To access the "Software/Options" dialog, select "System" and press the SETUP or MENU key. The menu is divided into the following sections: ● "Firmware" ● "Hardware Options" ● "Software Options" General Instrument Settings
