What's New
Version 7.00 at Introduction
The Keysight InfiniiVision M9241/42/43A PXIe oscilloscopes were introduced with
version 7.00 of oscilloscope operating software.
The command set is most closely related to the InfiniiVision 3000T X-Series
oscilloscopes (and the 4000 X-Series, 3000 X-Series, 7000A/B Series,
6000 Series, and 54620/54640 Series oscilloscopes before them). For more
information, see "Command Differences From 3000T X-Series Oscilloscopes" on
page 41.

Command Differences From 3000T X-Series Oscilloscopes
The Keysight InfiniiVision M9241/42/43A PXIe oscilloscopes command set is most
closely related to the InfiniiVision 3000T X-Series oscilloscopes (and the
4000 X-Series, 3000 X-Series, 7000A/B Series, 6000 Series, and
54620/54640 Series oscilloscopes before them).
The main differences between the version 7.00 programming command set for the
InfiniiVision M9241/42/43A PXIe oscilloscopes and the 4.08 programming
command set for the InfiniiVision 3000T X-Series oscilloscopes are related to:
•
Two analog channels in a module (3000T X-Series oscilloscopes can have two
or four analog channels).
•
No digital channels (or pods, buses, or BTIMing or BSTate math functions).
•
No demo signals.
•
Adds 10 MHz REF connector (similar to 4000 X-Series oscilloscopes).
•
Adds precision measurements and math functions feature.
•
Adds commands for setting up coordinated triggers between multiple PXIe
oscilloscope modules in a chassis.
•
No USB triggering.
•
No XY or Roll timebase modes.
•

•
No dedicated FFT function, but you can choose FFT math function operations.
•
Adds FFT Phase math function (to previous FFT Magnitude math function).
•
FFT detectors are added.
•
FFT measurements are added: Adjacent Channel Power Ratio (ACPR), Channel
Power, Occupied Bandwidth, and Total Harmonic Distortion.
•
No LINE source for edge trigger.
•
No external input on pattern trigger (just the two analog channels).
•
Single-lane decoding supported for IIC and UART/RS-232.
•
No support for I2S, SPI, or FlexRay serial decode and triggering.
•
Internal file system locations are now on the PXIe chassis controller PC (instead
of /Agilent Flash/).
•
Frequency Response Analysis feature is added.
•
No printer setup (:HARDcopy comand) from within the remote interface.
•
No EXTernal source allowed for serial bus sources (as compared to DSO models
of the 3000T X-Series).
•
System dates and times are set by the PXIe chassis controller PC.

Basic Oscilloscope Program Structure / 52
Programming the Oscilloscope / 54
This chapter gives you an overview of programming the M9241/42/43A PXIe
oscilloscopes. It describes basic oscilloscope program structure and shows how to
program the oscilloscope using a few simple examples.
The getting started examples show how to send oscilloscope setup, data capture,
and query commands, and they show how to read query results.
NOTE
Language for Program Examples
The programming examples in this guide are written in Visual Basic using the Keysight VISA
COM library.

Getting Started
Basic Oscilloscope Program Structure
The following figure shows the basic structure of every program you will write for
the oscilloscope.
Initializing
To ensure consistent, repeatable performance, you need to start the program,
controller, and oscilloscope in a known state. Without correct initialization, your
program may run correctly in one instance and not in another. This might be due
to changes made in configuration by previous program runs or from the front panel
of the oscilloscope.
•
Program initialization defines and initializes variables, allocates memory, or
tests system configuration.
•
Controller initialization ensures that the interface to the oscilloscope is properly
set up and ready for data transfer.
•
Oscilloscope initialization sets the channel configuration, channel labels,
threshold voltages, trigger specification, trigger mode, timebase, and
acquisition type.
Capturing Data
Once you initialize the oscilloscope, you can begin capturing data for analysis.
Remember that while the oscilloscope is responding to commands from the
controller, it is not performing acquisitions. Also, when you change the
oscilloscope configuration, any data already captured will most likely be rendered.
To collect data, you use the :DIGitize command. This command clears the
waveform buffers and starts the acquisition process. Acquisition continues until
acquisition memory is full, then stops. The acquired data is displayed by the
oscilloscope, and the captured data can be measured, stored in acquisition
memory in the oscilloscope, or transferred to the controller for further analysis.
Any additional commands sent while :DIGitize is working are buffered until
:DIGitize is complete.
53
You could also put the oscilloscope into run mode, then use a wait loop in your
program to ensure that the oscilloscope has completed at least one acquisition
before you make a measurement. Keysight does not recommend this because the
needed length of the wait loop may vary, causing your program to fail. :DIGitize, on
the other hand, ensures that data capture is complete. Also, :DIGitize, when
complete, stops the acquisition process so that all measurements are on displayed
data, not on a constantly changing data set.
Analyzing Captured Data
After the oscilloscope has completed an acquisition, you can find out more about
the data, either by using the oscilloscope measurements or by transferring the
data to the controller for manipulation by your program. Built-in measurements
include: frequency, duty cycle, period, positive pulse width, and negative pulse
width.
Using the :WAVeform commands, you can transfer the data to your controller. You
may want to display the data, compare it to a known good measurement, or simply
check logic patterns at various time intervals in the acquisition.

Referencing the IO Library
No matter which instrument programming library you use (SICL, VISA, or VISA
COM), you must reference the library from your program.
In C/C++, you must tell the compiler where to find the include and library files (see
the Keysight IO Libraries Suite documentation for more information).
To reference the Keysight VISA COM library in Visual Basic for Applications (VBA,
which comes with Microsoft Office products like Excel):
1
Choose Tools > References... from the main menu.
2
In the References dialog, check the "VISA COM 5.5 Type Library".
3
Click OK.
55
To reference the Keysight VISA COM library in Microsoft Visual Basic 6.0:
1
Choose Project > References... from the main menu.
2
In the References dialog, check the "VISA COM 5.5 Type Library".
3
Click OK.
Opening the Oscilloscope Connection via the IO Library
PC controllers communicate with the oscilloscope by sending and receiving
messages over a remote interface. Once you have opened a connection to the
oscilloscope over the remote interface, programming instructions normally appear
as ASCII character strings embedded inside write statements of the programing
language. Read statements are used to read query responses from the
oscilloscope.
For example, when using the Keysight VISA COM library in Visual Basic (after
opening the connection to the instrument using the ResourceManager object's
Open method), the FormattedIO488 object's WriteString, WriteNumber, WriteList,
or WriteIEEEBlock methods are used for sending commands and queries. After a
query is sent, the response is read using the ReadString, ReadNumber, ReadList,
or ReadIEEEBlock methods.
The following Visual Basic statements open the connection and send a command
that turns on the oscilloscope's label display.
Dim myMgr As VisaComLib.ResourceManager
Dim myScope As VisaComLib.FormattedIO488
Set myMgr = New VisaComLib.ResourceManager
Set myScope = New VisaComLib.FormattedIO488
' Open the connection to the oscilloscope. Get the VISA Address from the
' Keysight Connection Expert (installed with Keysight IO Libraries Suite
).
Set myScope.IO = myMgr.Open("")
' Send a command.
myScope.WriteString ":DISPlay:LABel ON"
The ":DISPLAY:LABEL ON" in the above example is called a program message.
Program messages are explained in more detail in "Program Message Syntax" on
page 1355.
Initializing the Interface and the Oscilloscope
To make sure the bus and all appropriate interfaces are in a known state, begin
every program with an initialization statement. When using the Keysight VISA
COM library, you can use the resource session object's Clear method to clears the
interface buffer:
3
Getting Started
Dim myMgr As VisaComLib.ResourceManager
Dim myScope As VisaComLib.FormattedIO488
Set myMgr = New VisaComLib.ResourceManager
Set myScope = New VisaComLib.FormattedIO488
' Open the connection to the oscilloscope. Get the VISA Address from the
' Keysight Connection Expert (installed with Keysight IO Libraries Suite
).
Set myScope.IO = myMgr.Open("")
' Clear the interface buffer and set the interface timeout to 10 seconds
.
myScope.IO.Clear
myScope.IO.Timeout = 10000
When you are using GPIB, CLEAR also resets the oscilloscope's parser. The parser
is the program which reads in the instructions which you send it.
After clearing the interface, initialize the instrument to a preset state:
myScope.WriteString "*RST"
Using :AUToscale to Automate Oscilloscope Setup
The :AUToscale command performs a very useful function for unknown waveforms
by setting up the vertical channel, time base, and trigger level of the instrument.
The syntax for the autoscale command is:
myScope.WriteString ":AUToscale"
Using Other Oscilloscope Setup Commands
A typical oscilloscope setup would set the vertical range and offset voltage, the
horizontal range, delay time, delay reference, trigger mode, trigger level, and
slope. An example of the commands that might be sent to the oscilloscope are:
myScope.WriteString ":CHANnel1:PROBe 10"
myScope.WriteString ":CHANnel1:RANGe 16"
myScope.WriteString ":CHANnel1:OFFSet 1.00"
myScope.WriteString ":TIMebase:MODE MAIN"
myScope.WriteString ":TIMebase:RANGe 1E-3"
myScope.WriteString ":TIMebase:DELay 100E-6"
NOTE
Information for Initializing the Instrument
The actual commands and syntax for initializing the instrument are discussed in Chapter 6,
“Common (*) Commands,” starting on page 173.
Refer to the Keysight IO Libraries Suite documentation for information on initializing the
interface.
57
Vertical is set to 16 V full-scale (2 V/div) with center of screen at 1 V and probe
attenuation set to 10. This example sets the time base at 1 ms full-scale (100
ms/div) with a delay of 100 µs.
Example Oscilloscope Setup Code
This program demonstrates the basic command structure used to program the
oscilloscope.
' Initialize the instrument interface to a known state.
myScope.IO.Clear
myScope.IO.Timeout = 10000
' Set interface timeout to 10 seconds.
' Initialize the instrument to a preset state.
myScope.WriteString "*RST"
' Set the time base mode to normal with the horizontal time at
' 50 ms/div with 0 s of delay referenced at the center of the
' graticule.
myScope.WriteString ":TIMebase:RANGe 5E-4"
' Time base to 50 us/div.
myScope.WriteString ":TIMebase:DELay 0"
' Delay to zero.
myScope.WriteString ":TIMebase:REFerence CENTer"
' Display ref. at
' center.
' Set the vertical range to 1.6 volts full scale with center screen
' at -0.4 volts with 10:1 probe attenuation and DC coupling.
myScope.WriteString ":CHANnel1:PROBe 10"
' Probe attenuation
' to 10:1.
myScope.WriteString ":CHANnel1:RANGe 1.6"
' Vertical range
' 1.6 V full scale.
myScope.WriteString ":CHANnel1:OFFSet -0.4"
' Offset to -0.4.
myScope.WriteString ":CHANnel1:COUPling DC"
' Coupling to DC.
' Configure the instrument to trigger at -0.4 volts with normal
' triggering.
myScope.WriteString ":TRIGger:SWEep NORMal"
' Normal triggering.
myScope.WriteString ":TRIGger:LEVel -0.4"
' Trigger level to -0.4.
myScope.WriteString ":TRIGger:SLOPe POSitive" ' Trigger on pos. slope.
' Configure the instrument for normal acquisition.
myScope.WriteString ":ACQuire:TYPE NORMal"
' Normal acquisition.
Capturing Data with the :DIGitize Command
The :DIGitize command captures data that meets the specifications set up by the
:ACQuire subsystem. When the digitize process is complete, the acquisition is
stopped. The captured data can then be measured by the instrument or
transferred to the controller for further analysis. The captured data consists of two
parts: the waveform data record, and the preamble.
3
Getting Started
When you send the :DIGitize command to the oscilloscope, the specified channel
signal is digitized with the current :ACQuire parameters. To obtain waveform data,
you must specify the :WAVeform parameters for the SOURce channel, the FORMat
type, and the number of POINts prior to sending the :WAVeform:DATA? query.
The number of data points comprising a waveform varies according to the number
requested in the :ACQuire subsystem. The :ACQuire subsystem determines the
number of data points, type of acquisition, and number of averages used by the
:DIGitize command. This allows you to specify exactly what the digitized
information contains.
The following program example shows a typical setup:
myScope.WriteString ":ACQuire:TYPE AVERage"
myScope.WriteString ":ACQuire:COMPlete 100"
myScope.WriteString ":ACQuire:COUNt 8"
myScope.WriteString ":DIGitize CHANnel1"
myScope.WriteString ":WAVeform:SOURce CHANnel1"
myScope.WriteString ":WAVeform:FORMat BYTE"
myScope.WriteString ":WAVeform:POINts 500"
myScope.WriteString ":WAVeform:DATA?"
This setup places the instrument into the averaged mode with eight averages. This
means that when the :DIGitize command is received, the command will execute
until the signal has been averaged at least eight times.
After receiving the :WAVeform:DATA? query, the instrument will start passing the
waveform information.
Digitized waveforms are passed from the instrument to the controller by sending a
numerical representation of each digitized point. The format of the numerical
representation is controlled with the :WAVeform:FORMat command and may be
selected as BYTE, WORD, or ASCii.
NOTE
Ensure New Data is Collected
When you change the oscilloscope configuration, the waveform buffers are cleared. Before
doing a measurement, send the :DIGitize command to the oscilloscope to ensure new data has
been collected.
NOTE
Set :TIMebase:MODE to MAIN when using :DIGitize
:TIMebase:MODE must be set to MAIN to perform a :DIGitize command or to perform any
:WAVeform subsystem query. A "Settings conflict" error message will be returned if these
commands are executed when MODE is set to ROLL, XY, or WINDow (zoomed). Sending the
*RST (reset) command will also set the time base mode to normal.
59
The easiest method of transferring a digitized waveform depends on data
structures, formatting available and I/O capabilities. You must scale the integers to
determine the voltage value of each point. These integers are passed starting with
the left most point on the instrument's display.
For more information, see the waveform subsystem commands and corresponding
program code examples in Chapter 32, “:WAVeform Commands,” starting on page
1157.
Reading Query Responses from the Oscilloscope
After receiving a query (command header followed by a question mark), the
instrument interrogates the requested function and places the answer in its output
queue. The answer remains in the output queue until it is read or another
command is issued. When read, the answer is transmitted across the interface to
the designated listener (typically a controller).
The statement for reading a query response message from an instrument's output
queue typically has a format specification for handling the response message.
When using the VISA COM library in Visual Basic, you use different read methods
(ReadString, ReadNumber, ReadList, or ReadIEEEBlock) for the various query
response formats. For example, to read the result of the query command
:CHANnel1:COUPling? you would execute the statements:
myScope.WriteString ":CHANnel1:COUPling?"
Dim strQueryResult As String
strQueryResult = myScope.ReadString
This reads the current setting for the channel one coupling into the string variable
strQueryResult.
All results for queries (sent in one program message) must be read before another
program message is sent.
Sending another command before reading the result of the query clears the output
buffer and the current response. This also causes an error to be placed in the error
queue.
Executing a read statement before sending a query causes the controller to wait
indefinitely.
The format specification for handling response messages depends on the
programming language.
NOTE
Aborting a Digitize Operation Over the Programming Interface
When using the programming interface, you can abort a digitize operation by sending a Device
Clear over the bus (for example, myScope.IO.Clear).
3
Getting Started
Reading Query Results into String Variables
The output of the instrument may be numeric or character data depending on
what is queried. Refer to the specific command descriptions for the formats and
types of data returned from queries.
The following example shows numeric data being returned to a string variable:
myScope.WriteString ":CHANnel1:RANGe?"
Dim strQueryResult As String
strQueryResult = myScope.ReadString
MsgBox "Range (string):" + strQueryResult
After running this program, the controller displays:
Range (string): +40.0E+00
Reading Query Results into Numeric Variables
The following example shows numeric data being returned to a numeric variable:
myScope.WriteString ":CHANnel1:RANGe?"
Dim varQueryResult As Variant
varQueryResult = myScope.ReadNumber
MsgBox "Range (variant):" + CStr(varQueryResult)
After running this program, the controller displays:
Range (variant): 40
Reading Definite-Length Block Query Response Data
Definite-length block query response data allows any type of device-dependent
data to be transmitted over the system interface as a series of 8-bit binary data
bytes. This is particularly useful for sending large quantities of data or 8-bit
extended ASCII codes. The syntax is a pound sign (#) followed by a non-zero digit
representing the number of digits in the decimal integer. After the non-zero digit is
the decimal integer that states the number of 8-bit data bytes being sent. This is
followed by the actual data.
For example, for transmitting 1000 bytes of data, the syntax would be:
NOTE
Express String Variables Using Exact Syntax
In Visual Basic, string variables are case sensitive and must be expressed exactly the same
each time they are used.
61
The "8" states the number of digits that follow, and "00001000" states the number
of bytes to be transmitted.
The VISA COM library's ReadIEEEBlock and WriteIEEEBlock methods understand
the definite-length block syntax, so you can simply use variables that contain the
data:
' Read oscilloscope setup using ":SYSTem:SETup?" query.
myScope.WriteString ":SYSTem:SETup?"
Dim varQueryResult As Variant
varQueryResult = myScope.ReadIEEEBlock(BinaryType_UI1)
' Write learn string back to oscilloscope using ":SYSTem:SETup" command:
myScope.WriteIEEEBlock ":SYSTem:SETup ", varQueryResult
Sending Multiple Queries and Reading Results
You can send multiple queries to the instrument within a single command string,
but you must also read them back as a single query result. This can be
accomplished by reading them back into a single string variable, multiple string
variables, or multiple numeric variables.
For example, to read the :TIMebase:RANGe?;DELay? query result into a single
string variable, you could use the commands:
myScope.WriteString ":TIMebase:RANGe?;DELay?"
Dim strQueryResult As String
strQueryResult = myScope.ReadString
MsgBox "Timebase range; delay:" + strQueryResult
When you read the result of multiple queries into a single string variable, each
response is separated by a semicolon. For example, the output of the previous
example would be:
Timebase range; delay: ;
To read the :TIMebase:RANGe?;DELay? query result into multiple string variables,
you could use the ReadList method to read the query results into a string array
variable using the commands:
myScope.WriteString ":TIMebase:RANGe?;DELay?"
Dim strResults() As String
strResults() = myScope.ReadList(ASCIIType_BSTR)
MsgBox "Timebase range: " + strResults(0) + ", delay: " + strResults(1)

To read the :TIMebase:RANGe?;DELay? query result into multiple numeric
variables, you could use the ReadList method to read the query results into a
variant array variable using the commands:
myScope.WriteString ":TIMebase:RANGe?;DELay?"
Dim varResults() As Variant
varResults() = myScope.ReadList
MsgBox "Timebase range: " + FormatNumber(varResults(0) * 1000, 4) + _
" ms, delay: " + FormatNumber(varResults(1) * 1000000, 4) + " us"
Checking Instrument Status
Status registers track the current status of the instrument. By checking the
instrument status, you can find out whether an operation has been completed,
whether the instrument is receiving triggers, and more.
For more information, see Chapter 37, “Status Reporting,” starting on page 1301
which explains how to check the status of the instrument.
SCPI Programmer's Guide
4 Sequential (Blocking) vs.
Overlapped Commands
IEEE 488.2 makes the distinction between sequential and overlapped commands
(and queries):
•
Sequential commands also known as blocking commands, finish their task
before the execution of the next command starts.
These oscilloscope commands and queries are sequential (blocking):
•
:AUToscale
•
:DIGitize
•
:WMEMory:SAVE
•
:WAVeform:DATA?
•
Overlapped commands run concurrently. Commands following an overlapped
command may be started before the overlapped command is completed.
Some oscilloscope commands are overlapped. For example, the oscilloscope's
save and recall commands are overlapped as well as some commands that
perform analysis.
With sequential (blocking) commands and queries, the oscilloscope is expected to
stop processing inputs, including additional remote commands and queries as
well as front panel knobs, until completed.
Pausing Execution
Between
Overlapped
Commands
With overlapped commands, you can use the *OPC? query to prevent any more
commands from being executed until the overlapped command is complete. This
may be necessary when a command that follows an overlapped command
interferes with the overlapped command's processing or analysis. For example:
:RECall:SETup "setup.scp";*OPC?;:RECall:ARBitrary "arb_wfm.csv"
You can also use the *ESR? query to look at the OPC bit (bit 0) in the Standard
Event Status Register to determine when an operation is complete.
4
Sequential (Blocking) vs. Overlapped Commands
Pausing Programs
Until Sequential
(Blocking)
Commands are
Complete
Sequential (blocking) commands do not prevent additional commands from being
sent to the queue or cause the remote program to wait. For example, if your
program does something like:
myScope.WriteString ":DIGitize"
Debug.Print "Signal acquired."
The "Signal acquired" message will be written immediately after the :DIGitize is
sent, not after the acquisition and processing is complete.
To pause the program until a sequential (blocking) command is complete, you
must wait for a query result after the sequential (blocking) command. For example,
in this case:
Public strQueryResult As String
myScope.WriteString ":DIGitize;*OPC?"
strQueryResult = myScope.ReadString
Debug.Print "Signal acquired."
The "Signal acquired" message will be written after the acquisition and processing
is complete. The *OPC? query is appended to :DIGitize with a semi-colon (;), which
essentially ties it to the same thread in the parser. It is immediately dealt with once
:DIGitize finishes and gives a "1" back to the program (whether the program uses it
or not), allowing the program to move on.
When using a query to wait until a sequential (blocking) command is complete, it
is possible for the sequential (blocking) command execution to take longer than
the I/O timeout, in which case, there will be a timeout error while waiting for the
query results. You can increase the I/O timeout or have your program poll the
Status Byte Register using the IO libraries' unblocked ReadSTB function to wait for
execution completion.
Using Device Clear
to Abort a
Sequential
(Blocking)
Command
When sequential (blocking) commands take too long or fail to complete for some
reason, you can send a Device Clear over the bus to clear the input buffer and
output queue, reset the parser, and clear any pending commands.
