2.3 Bus Commands Bus commands refer to internal interface communications exchanged when the bus is set to the command mode (when the ATM line is set at "L"). The table below shows a list of bus commands. Table 2-4 Details of Bus Commands Bus Command Operations DCL (Device clear) Initializes the exchange of messages among all the devices connected to the GPIB bus. SDC (Selected Device Clear) Initializes the exchange of messages among addressed devices. The operations are the same as those for DCL. GET (Group Execute Trigger) Performs the same operations as those triggered when the Start/Stop key is pressed IFC (Interface Clear) Init~allzes the ~nterface.

2.5 Setting GPlB To use GPIB as a remote interface, set the device to the local mode and set the address by performing key input on the front panel.

2.6 Initializing the Device IEEE488.2 st~pulates three levels of system initialization: initialization of the bus, message and device. Table 2-6 Types of System lnitialization Level Type of Initialization Outline 1 Initialization of the bus Initializes the functions of all the interfaces connected to the bus with the IFC message from the controller. 2 Initialization of the message Disables the function to report to the controller that the initialization of the exchange of messages among all the devices on GPIB and relevant operations are completed by DCL, one of the GPIB bus commands, and that the initial- ization of the exchange of messages among specified devices on GPIB and relevant operations are completed by SCL, also one of the GPIB bus com- mands. 3 Initialization of the device Returns the device to the original state unique to the device by *RST, regard- less of the status during past usage. 2.6.1 lnitializing the Bus IFC: Initialization of the bus by the IFC statement Function: Switches the IFC line into an active state for about 100 ps and initializes the interface function of all the devices connected to the GPIB bus line. IFC can be transmitted only by the system controller. 2.6.2 lnitializing the Message DC'L and SDC: Initialization of the exchange of messages by the DCL and SDC bus commands Initializes the exchange of messages for all the devices on GPIB or specified devices on GPIR. Functions: Initialization of the message exchange is aimed at setting preparations to enable the controller to send new instructions in the event that sections related to the message exchange in devices are set in a state inappropriate for the control to be executed from the controller because, for example, other programs were executed earlier, although changing the panel setting is not required. DCL: Initializes the message exchange among all the devices on GPIB SDC: Initializes the message exchange among specified devices.

The configuration of the status registers of the MP1777A conforms to the SCPI stipulations. (SCPI: Standard Command for Programmable Instruments, see the Section 7 for more information.) This section provides descriptions of the configuration of status registers and definition of the status register bit specific to the device. 6.1 Configuration of MP1777A Status Registers ................................... 6-2 ........................................ 6.2 Status Registers Specified by IEEE488.2 6-4 6.3 Status Register Specified by SCPl ................................................. 6-6 6.4 Status Register Specific to MP1777A .......................................... 6-7 6.5 Reading, Writing and Clearing Status Registers ............................. 6-8

6.1 Configuration of MP1777A Status Registers SCPI stipulates that the status register configuration must conform to the configuration specified by IEEE488.2 and incorporate the SCPI OPERation status register and QUEStionable status register specific to SCPI. The figure below shows a simple block diagram of status registers mounted on this device.

Fig. 6-1 Block Diagram of Status Registers Registers specified by IEEE488.2 are event register and status byte register. Register specified by SCPI is OPERation status register. Device-specific register is INSTrument status register.

Status registers excluding the registers specified by IEEE488.2 are configured as follows. Condition Transition Event Event enable register filter register register . . . . - Summary Message Fig. 6-2 Block Diagram of each Status Register Table 6-1 Definitions of Register and Filter Register and Filter Definition Condition register Monitors the device status and performs real-time change in accordance with the device Transition filter status. For this reason, this register does not store the status. Sets the condition register details to the event register The transition filter comes in three modes, depending on the changes of the condition regis- ter to be evaluated. Positive direction change: The event becomes true only when the corresponding condition changes from false to true. Negative direction change: The event becomes true only when the corresponding condition changes from true to false Both direction change: The event becomes true when a change into the positive or negative direction takes place. Event register Stores the output of the transition filter. Event enable register Selects the bit of corresponding Event Reg~ster to trigger a sh~ft of summary message to true.

6.2 Status Registers Specified by IEEE488.2 IEEE488.2 specifies the two status registers shown below. Table 6-2 Definitions of Status Registers Specified by IEEE488.2 Status Register Definition Status byte register A register to set RQS and seven summary message bits. Being used in combination with the service request enable register, this register sets SQR ON when the logical OR of the two is not zero. RQS is system reserved in bit 6 and this bit reports to the external controller the presence of service request. Standard event status register Sets eight types of events the device will encounter as standard events. The log~cal OR output bit is summarized and displayed in bit 5 of the status byte register as' the ESB (Event Status Bit) summary message. Standard event status Standard event enable register status register - -@+- OPC 1 ---- 1 NOT USED - 2 . 2 QYE DDE EXE CME NOT PON USED Service request Status byte 1 enable register - - register - jO/ NOTUSED 1 Errorlevent queue I Output queue F 1 - 2 2 QUE - 3 - 3 QUES - 4 - 5 . ---5 ESB - status register OPERation status register . .

The MP1777A adopts SCPI (Standard Commands for Programmable Instruments) as commands to perform remote con- trol. This section provides the outline of SCPI and explanations of the command system. This section and subsequent Sectlons describe the examples of command use and response as follows. > Program message (program command. query command) < Response .............................................................................................. 7.1 Outline 7-2 ......................................................................... 7.2 Command Structure 7-3 7.3 Command Description Method ........................................................ 7-4 ............................................................... 7.4 Compounding Commands 7-5 7.5 Parameter ......................................................................................... 7-6

7.1 Outline SCPI is a device command language defined by the SCPI consortium and is independent from the hardware. SCPI is designed to shorten the period for development of automatic measuring instrument (ATE). For this reason, the programming environments such as the device control and data handling are made consistent. Moreover, it is characterized by its ability to perform totally even control of devices of the same model as well as devices of different models compatible with each other that are equipped with the same functions.

7.2 Command Structure The SCPI command form a hierarchical structure. Commands are divided into groups, each of which consists of com- mands of similar functions, and each group forms a hierarchical structure called the subsystem. This specification expresses these subsystems by the command tree as shown below. SCPI allows the same headers to be present in a tree and the difference in the location of the header corresponds to the difference in the function. Therefore, a command must be described in a full path up to the header to be used. SOURce - : TELecom : BRATe : BRATe? : EQUAlizer : EQUAlizer? Fig. 7-1 Example of SCPI Command Tree

Command Description Met hod : SOURce : TELecom : BRATe ~brate> : SOURce : TELecom : BRATe? : SOURce : TELecom : EQUAlizer : SOURce : TELecom : EQUAlizer? Fig. 7-2 Example of SCPl Commands The command tree shown in the previous section consists of the commands shown above. The section below provides explanations of the stipulations concerning descriptions of commands. A command begins with a colon ( : ). Or, a command is structured by concatenating headers n ith a colon ( : ).

Headers come in short and long forms. The short form signifies an abbreviated form of the long form. A command is interpreted as the same command whether it is expressed in the short or long form. (The short and long form can be mixed.) This specification uses the uppercase and lowercase characters to distinguish the short and long forms. (The expressed in uppercase characters refers to the short foml.) However, the uppercase and lowercase characters distinguished when they are actually used. section are not Example: Long form > : SOURce : TELecom : BRATe M9953 Short form > sour : TEL : BRAT M99.53 Long+short form > Sour : TELeconi : BRAT M9953 The section in the brackets ( [ and ] ) expresses the option node. The header enclosed by the brackets ( [ and ] ) can be abbreviated, and the abbreviated and non-abbreviated forms of a header are interpreted as the same command. Example: When a header is not abbreviated > : DISPlay : DSELect : NAME "SETup" When a header is abbreviated > : DISPlay : DSELect : "SETup" At least one space character is always inserted between a command and a parameter. Two or more parameters are separated by a comma ( , ).

7.4 Compounding Commands Commands can be compounded by using semi-colon ( ; ) as shown by the example below. The second command is also referenced as the command located at the same level as the lowest hierarchical level of the first command. For this reason, the second command can be described in a full path as shown by Example 1. However, as Example 2 shows, headers located in the layer above Type can also be abbreviated. Example I : > : SENSe : TELecom Example 2: > : SENSe : TELecom : PATTem : TYPE UWORd16 ; : SENS : TELecom : PATTern : UWORd " 1 1001 1001 1001 100" : PATTem :TYPE UWORdl6 ; UWORd "1 10011001 1001100"

Parameter The table below shows types of parameters used by this measuring instrument This operation manual expresses parameter types in lowercase characters enclosed by angled brackets ( < and > ) in the table below. Moreover, the type corresponding to the parameter type, specified by IEEE488.2 (or SCPI), is expressed in uppercase characters. The correspondence between each parameter type and specified by IEEE488.2 (or SCPI) is de- scribed for each command. Table 7-1 Details of Parameter Type Parameter T V D ~ (Defined by SCPI) , ..etc Expresses a decimal digit. such as MINirnum and MAXimum are included as special numerical value type data. The numerical values used by this device are mainly integer type. Therefore, the fractional part is rounded. Expresses a theoretical value. OFF or 0 corresponds to false and ON or 1 corresponds to true. The setting can be done by O and 1, or OFF and ON. However, the setting for the response to a query must be done by O or I. Expresses a character string, made of ASCII characters enclosed by single quotation marks ( ' ) or double quotation marks ( " ) . Either long or short form can be used. Example: 'LOF : M 139' or "LOF : M 139" Expresses a character data. Expressed in a short character string that corresponds to the setting details Either the long or short form can be used.

8.2 Buffer Size Stipulations A response in the format explained earlier is sent from the device to the controller. Therefore, the controller must have a buffer of a size enough to accept the response. When the commands of this device are used, a maximum of 255 bytes of buffer space will suffice.

8.3 Device-Specif ic Commands The following section provides details of the device-specific commands. As the command descriptions are classified by the subsystem, see the Appendix D correspondence between commands and screens for more information on the correspondence with screens. Incidentally, the device-specific commands supported by this device are sequential commands with some exceptions An explanation is glven for commands other than sequential commands every time they come up. When a set value by a program command causes set values for other items to become unacceptable, they will be changed to allowed values. Moreover, the measurement starts again when settings are modified during measurement. See the details of the operation method in this operation manual for conditions to change set values for other items and to execute restart. The following section shows examples of descriptions of commands. When a restriction on command use exists, an item called the restriction is added to the example below. Program command Parameter type (SCPI, device-specific) I 1 Parameter type (IEEE488.2, SCPI) I 1 / I i : SENS : TEL : RANG -.

Sets the range of jitter reception at UI 4. > : SENS : TEL : RANG U14 4 I i \% \ Parameter details Example of command use The right angled blacket ( > ) at the header shows that the segment is a Program mes- sage and left angled blacket ( < ) shows it is a Response.

8.3.1 INSTrument Subsystem The INSTrument subsystem is used to specify the same setting for the transmission and reception or independent setting for each. : INSTrurnent : COUPle 7 : COUPle? : INSTrument : COUPle Command type Sequential command Parameter Function Restriction = ALL ............. Tx&Rx (Same) NONE .......... Tx/Rx (Independent) Specifies the selection of whether to establish the same setting for the transmission and reception modules or independent setting for each. When the mode is switched from Tx/Rx to Tx&Rx, the set value for Rx is set for the Bit Rate. Example of use Sets the same setting for the transmission and reception. > : INSTrument : COUPle ALL : INSTrument : COUPle? Command type Sequential command Response = Same as : INSTrument : COUPle Function Makes a query of whether the setting is the same for the transmission and reception Example of use > : INSTrument : COUPle? < ALL
