Unless specified as "Bonded," this topic primarily describes capabilities for use when the Configuration is Independent, 2 Tx Coherent, or MIMO. For bonded configurations, do not use SCPI commands described in this topic unless they are specified as "Bonded."
For bonded configurations, be sure to use bonding-supported SCPI commands only. Using unsupported SCPI commands in a bonded configuration will impair the fidelity of the waveform. In these cases, the unsupported SCPI commands are still accepted, but no error or warning is generated.
The vector modulation bandwidth is based on the instrument’s optional capabilities and operating settings. The bandwidth is as follows:

OFF When the mode is real-time, the state is Off since real-time internal settings are not ready after recall/preset. |
|
Coupling |
When vector modulation is turned ON while Enable Amplitude Control is OFF and I/Q Modulation Source is Internal, I/Q Modulation On is set to ON. When vector modulation is turned OFF while Enable Amplitude Control is ON or I/Q Modulation Source is External, no coupling occurs; meaning the current state of I/Q Modulation On and I/Q Modulation Source is unchanged. When Vector Modulation Signal Mode is Real-Time and Real-Time application internal settings are not set, Enable Vector Modulation is set to Off and is unchangeable. |

Applies to the M9383B VXG-m and M9384B VXG only.
Option PCH only.
Sets synchronization role of the channel in the Independent configuration. When the channels are configured to synchronize, one as Primary and the other as Secondary, the system will be set up to start both baseband channels synchronously, using Primary’s trigger. This feature is available with Option PCH only.
When configuring a channel as the Primary, the phase relationship of baseband signal and reference are repeatable between turning on and turning off the signal or by triggering playback (with trigger being re-clocked to the internal 10-MHz reference).
This control doesn’t appear in the Tx Coherent configurations, in which two channels are always configured to be synchronized with Ch1 Primary and Ch2 Secondary.
The Tx Coherent configuration is only available with Option PCH.
Sync Off – The channels are not synchronized. Each signal plays based on its trigger settings.
Primary – The channel participates in synchronization as the Primary. Even selection of Primary alone may be useful as the relationship of start play and system clock is repeatable from start to start.
Secondary – The channel participates in synchronization as the Secondary. Trigger settings of this channel are ignored (and the Trigger GUI tile disappears) since the signal starts to play with the Primary.

Available with Option 8SG. This feature disables or enables the I/Q component of a signal without adjusting any power relationships between any signals, including noise. The channel will behave as if the signal is not muted, but the signal will not contribute any power to the outputs of the channel. Turning the signal off and on with this feature means that there is no other disruption to the outputs besides this signal having no power or the requested power. For instance, triggering of the signal is not disabled when muting occurs. Markers also continue to be output. This feature is independent of the Signal Attenuation feature.

For channel bonding configurations, note the following:
The trigger configuration can be adjusted after the bonding process has completed.
Use Signal 1 for SCPI commands when configuring the triggering.
Sets the trigger mode (or type), determining how the waveform plays when triggered. These mode selections are described in the table below.
Triggers control the playback by telling the signal generator when to play the modulating signal (waveform). Depending on the trigger settings, the waveform playback can occur once or continuously.
A trigger signal comprises both positive and negative signal transitions (states), which are also called high and low periods. You can configure the signal generator to trigger on either state of the trigger signal. It is common to have multiple trigger signals, also referred to as trigger occurrences or events, occur when the signal generator requires only a single trigger. In this situation, the signal generator’s action is based on the setting within the trigger mode.
When you select a trigger mode, you may lose the signal (carrier plus modulation) from the RF output until you trigger the waveform. This is because the signal generator sets the I and Q signals to zero volts prior to the first trigger event, which suppresses the carrier. After the first trigger event, the waveform’s final I and Q levels determine whether you will see the carrier signal or not (zero = no carrier, other values = carrier visible). At the end of most files, the final I and Q points are set to a value other than zero.
Continuous: The framed data sequence repeats continuously until you turn the signal off or select a different waveform, or trigger mode. The sequence restarts every time the previous playback is completed.
Single: The framed data sequence plays once for every trigger received.
Segment Advance: For M9484C. The trigger controls the segment advance within a waveform sequence. To use this choice, a waveform sequence must be the active waveform.

Selects the waveform’s response to a trigger signal while using the continuous trigger mode.
Free Run: The waveform is immediately triggered and played when Enable Vector Modulation Signal is turned on and a valid waveform file is selected. The waveform repeats until you turn off Enable Vector Modulation Signal, select another trigger, or choose another waveform file. Triggers received while the waveform is playing are ignored. For M9484C. Free Run is not available when Trigger Source is Global Trigger.
Trigger & Run: The waveform waits for a trigger before it starts playing. When the waveform receives the trigger, it plays continuously until you turn off Enable Vector Modulation Signal, select another trigger, or choose another waveform file. Subsequent triggers are ignored.
Reset & Run: The waveform waits for a trigger before it starts playing. When the waveform receives the trigger, it plays continuously. Subsequent triggers reset the waveform to the beginning. For a waveform sequence, it means the beginning of the first segment in the sequence. For M9484C, Reset & Run is not available when Trigger Source is Global Trigger and the Global Trigger Source is Immediate.

For M9484C with Signal Mode set to Waveform File. When the waveform file selected is a waveform sequence, the trigger mode of segment advance (SADVance) controls the execution of the sequence.
Remote command only.
Segment advance can be configured for single or continuous execution. When the instrument receives multiple trigger occurrences when only one is required, the signal generator uses the first trigger and ignores the rest.
Single: Each segment in the sequence requires a trigger to play, and a segment plays only once, ignoring a segment’s repetition value. The following list describes a sequence’s playback behavior with this choice:
After receiving the first trigger, the first segment plays to completion.
When the waveform receives a trigger after a segment completes, the sequence advances to the next segment and plays that segment to completion.
When the waveform receives a trigger during play, the current segment plays to completion. Then the sequence advances to the next segment, and it plays to completion.
When the waveform receives a trigger either during or after the last segment in a sequence, the sequence resets and the first segment plays to completion.
Continuous: Each segment in the sequence requires a trigger to play. After receiving a trigger, a segment plays continuously until the waveform receives another trigger. The following list describes a sequence’s playback behavior with this choice:
After receiving the first trigger, the first segment plays continuously.
A trigger during the current segment play causes the segment to play to the end of the segment file, then the sequence advances to the next segment, which plays continuously.
When last segment in the sequence receives a trigger, the sequence resets and the first segment plays continuously.

Sets the trigger source.
Bus: The trigger is initiated programmatically in the software. Use the *TRG command to initiate the trigger for all groups (channels), and in the case of M9484C with Option 8SG for all signals. Use *TRG to initiate synchronous programmatic triggering of the instrument. To initiate a trigger programmatically for an individual group (channel), and individual signal, use the [:SOURce]:GROup<group>:SIGNal<signal>:TRIGger:IMMediate command.
Key: The trigger is initiated manually in the software, using the Trigger button. Because there is one trigger button for the instrument, if you have multiple groups (channels) and, in the case of M9484C with Option 8SG, multiple signals, all groups and signals are triggered together.
External: Enables the triggering of the waveform playing by an externally applied signal at the following connector.
On an M9383B, Ext1 of M9343A at slot 15 (CH1) or slot 7 (CH2)
On an M9384B, Ch 1 Ext 1 or Ch 2 Ext 1 on the rear panel.
On an M9484C, the connector must be configured via the External Trigger Source setting.
Immediate: Enables immediate triggering of the waveform playing.
Global Trigger Available on the M9484C, this trigger source must be used when synchronized playback is needed across channels in instruments with multiple channels. There is one global trigger for the instrument; all signals and groups (channels) utilizing Global Trigger will be affected by changes to the Global Trigger settings.
Both KEY and BUS are software triggers and are not intended to be configured on the instrument at the same time. Even though the Trigger Source is configured on a group and signal basis, thus one signal could be configured for KEY and another for BUS, it is intended you will be either using the instrument in manual operation (via front-panel interface) or programmatically (via remote SCPI commands). You can encounter unexpected triggering if you intermix KEY and BUS triggering at the same time. They both trigger the hardware in the same way.

On MXG-B, the Trigger Source command (:RAD:ARB:TRIG) doesn’t have the IMMediate selection. Due to this difference, SCPIs related to Trigger don’t behave in exactly the same way as MXG-B. The following table shows returned values of Trigger Source and Continuous Mode in N5182B MXG and VXG when the SCPI commands are sent in the following order. The user from N5182B MXG should understand the behavior difference.

Signal Trigger Delay applies to the M9484C only. It delays the vector modulation (I/Q) of a signal with respect to any trigger event, including the initial trigger for immediate trigger.
For instruments with Option 8SG, this allows delaying one signal versus other signals regardless of trigger type. When using more than one signal, each signal’s delay should be offset from other signals if the waveform being played on each signal is too correlated. If signals are too correlated, the baseband DAC overrange error may occur.

For the selected Group, the External Trigger Source is composed of the common set of available selections for that group. For example, in Nx2 MIMO for instruments with AN1 the available GROup1 selection is 1, for instruments without AN1 the available GROup1 selection are 1, or 2, or 3. (For any configuration Groups 2 and above the available selections are always 1, or 2, or 3.) |
|

Clears the phase accumulation resulting from a non-zero frequency offset.
When using frequency offset, dynamic range is managed by the instrument to reduce DAC overrange. Phase Accumulator Reset restores the dynamic range when the frequency offset is set to zero.
When the baseband Frequency Offset is non-zero, the hardware rotator accumulates phase shift of the baseband signal. This residual phase remains even after the offset value is returned to zero. While there is a non-zero residual phase present in the signal, the instrument will automatically prevent DAC overrange errors from occurring by scaling the signal down by 1/square root of 2.

Notes |
This command clears the phase accumulation and thus zeros the phase shift. For M9484Cwith Option 8SG: This command only performs a reset if the signal’s frequency offset is 0 Hz. If more than one signal is active at the same time and any have a non-zero frequency offset, all of the signals will still be scaled down by 1/square root of 2. |

This capability requires license model N7621APPC.
The number of samples of a Multitone signal is determined by Tones and Tone Spacing when the required BW is much smaller than the maximum sample rate. However, when the required BW becomes larger and the max Sample Rate needs to be used, the number of samples of Multitone signal is determined mainly by the greatest common divisor (GCD) of the max Sample Rate and Tone Spacing.
For example, assuming the max Sample Rate is 2.56 GHz, if Tones and Tone Spacing are set to 201 and 12,111,111 Hz respectively, the GCD is 1 Hz, which requires the signal to be 1 sec long in time. Therefore 2.56 G samples are required, which is far larger points than the size of internal buffer array (64 M samples). In this case, an error is issued, and Multitone signal is not generated.
If the tone spacing is changed to 12,111,100 Hz, the GCD becomes 100 Hz and the signal length will reduce to 0.01 sec. It is 25.6 M samples and small enough to fit in the buffer.
Remote command only.
This is an action command that imports the tone table data from the multitone file. The multitone file is a text file that consists of four columns separated by spaces, tabs, or commas. The four columns are status, frequency (Hz), relative amplitude (dB) and phase (degree). Only UTF-8 encoding with and without BOM is supported
The following is the example of the multitone file in which five tones are defined with 1.0 MHz spacing. The relative amplitude of tones are all zero.
1 -2000000 0 40.11
1 -1000000 0 167.88
1 0 0 277.88
1 1000000 0 236.63
1 2000000 0 155.84
The multitone file needs to satisfy the following conditions, otherwise it’s rejected with an error message.
The tone frequencies in the file need to be equally spaced. The tone frequencies are rounded to the resolution of Tone Spacing before the check.
The bandwidth of tones, the maximum - the minimum tone frequencies, is less than or equal to the vector modulation bandwidth that varies based on the channel frequency. See Vector Modulation Bandwidth Limitations.
The number of Tones and Tone Spacing need to be within their specified ranges.
The center of tones is at frequency zero.
The tone frequencies are in the ascending order.
The values are separate with a single space. Consecutive multiple spaces are not allowed.
The RMS of generated waveform is not too small. For example, when many tones have the same phase, an error message appears.
The MTONE MSUS can be used to specify the multitone file. See File Location and Default Folders for more details about MTONE MSUS. With MTONE, you can send or select a multitone file as shown below.

Launches the selected Signal Studio application. All available Signal Studio applications are listed for the instrument.
Signal Studio applications, such as Custom Modulation (N7608C) support auto configuration. If Signal Studio supports auto configuration, it is automatically connected to the specified Signal of localhost VXG when launched from this control. For example, when it’s launched from the Signal block of Ch2, it is connected to Ch2. For Signal Studio applications that do not support auto configuration the VXG is not automatically connected and must be done manually.
For 2-channel instruments:
If the selected Signal Studio application is already running on one of the channels, the existing Signal Studio is used instead of starting a new instance.
If the instance of Signal Studio is already running on a channel (for example, channel 1), and you wish to use the other channel (channel 2), close the existing instance and relaunch a new instance from the other channel (channel 2).

Allows you to select waveform data to play. Both waveform data in ARB memory and non-volatile memory can be selected.
If you have Option 8SG, waveform files assigned to the same signal group must have unique file names. The ARB waveform memory references the file name alone and does not distinguish between different directories. For more information, refer to ARB Waveform Memory.
When waveform data in non-volatile memory is selected, it first uploads the data to the ARB memory and the uploaded data is played. The data in non-volatile memory can be specified either with a path to the file or MSUS for non-volatile waveform data. i.e. "SNVWFM" and "NVWFM."
Waveform on the arb memory can be selected either with "SWFMn" or "WFMn." See also ARB Waveform Memory.
Even when the file with the same name on the non-volatile memory is selected, the waveform is uploaded to the arb memory.
When a filename that does not exist is given to this command, the value is not updated and -257, "File name error" is issued. Setting an empty string, e.g. GRO:SIGN:WAV "", ends up with the same result. The value isn’t changed, and the error is issued.
File names and file paths must comprise ASCII characters only. Otherwise, a "File name not found" error occurs. In addition, a file name cannot contain a comma or a semicolon.

Two floating-point numbers (one for I and the other for Q) delimited by a comma, a tab or a whitespace, should appear in each line. Each line can have more than two values, but only the first two values are read as IQ point data. For example, the csv file may have values for I, Q, Marker1, Marker2, Marker3, and Marker4 in one line. In this case, only the first two values in the line are imported as an IQ point. The rest of the values are discarded. Only UTF-8 encoding with and without BOM is supported. If the max abs value of I or Q is less than or equal to 1.0, no scaling is applied to the IQ data. If it is more than 1.0, the IQ data is normalized with the max abs value of I or Q. |

The waveform header contains waveform properties such as the sample rate and the RMS value.
A secure waveform file (*.wfm) and a sequence file (*.seq) each contain a header. Other files don’t contain a header but an external header file is supported. An external header file must have the same name as the waveform file with an extension of .whd or .HEADER. It must be placed in the same folder as the associated waveform file.
When a waveform file is selected, the following settings are updated:
Sample Rate if specified in the header.
Scale if specified in the header.
RMS
If a value is specified in the header, it is updated to that value. Otherwise,
If a secure waveform file is selected, it is set to 1.0.
If a sequence file is selected and all the waveforms referenced in the header have been uploaded, it is calculated from the RMS value and the length of the waveforms.
If a non-secure waveform file is selected, it’s calculated from the waveform.
Occupied Bandwidth
If a value is specified in the header, it is updated to that value.
If a value is not specified but the Sample Rate is specified in the header, it is updated to that Sample Rate.
Manually updating the Occupied Bandwidth GUI value does not adjust the occupied bandwidth of the waveform. Rather, it sets the frequency span over which the RF flatness correction and dynamic range optimizations occur. See Optimize Dynamic Range with OBW for more information.
ALC Hold Marker Routing if specified in the header.
RF Blanking Marker Routing if specified in the header.
The following table shows MSUS examples.

Auto folder selection works for this setting in the same way as memory commands, defined in the ARB Waveform Memory topic. See also Auto Folder Selection by Extension in that same topic for details.
With Auto Folder Selection, the folder of waveform file on non-volatile memory is automatically selected by the extension of file name when relative file path is given as command parameter. For example, when
GRO:SIGN:WAV "abc.wfm"
is sent, the software looks at <Documents>\Keysight\PathWave\SignalGenerator\Waveforms\ folder as a location of waveform file.
If the extension is not supported by Auto Folder Selection, the file path is determined based on the default folder, <Documents>\Keysight\PathWave\SignalGenerator.
The following table shows some of waveform file path examples and which folders are selected.

If an inappropriate file extension is used, a non-intuitive folder is selected. The following table shows such examples.
|
SCPI command example |
Folder |
|---|---|
|
GRO:SIGN:WAV "abc.sgen" |
<Documents>\Keysight\PathWave\SignalGenerator\States\ |
|
GRO:SIGN:WAV "..\abc.sgen" |
<Documents>\Keysight\PathWave\SignalGenerator |
An .sgen file is usually a state file, in which instrument settings are saved, however, it is possible to create a signal file with .sgen and then select it as a waveform file. For example, you can send your waveform file with
:MMEM:DATA "abc.sgen", …
and select it with
:GRO:SIGN:WAV "abc.sgen"
This works perfectly, however, the file is saved in the "States" folder under the default folder because Auto Folder Detection designates the "States" folder as the location for .sgen files.
If the number of samples in the specified waveform file is smaller than the Segment Length Minimum or is not a multiple of the Waveform Quantum, the VXG can automatically extend it by either repeating the waveform or appending zeros at the end. The extension method can be configured by the Waveform Extension Method. A message is shown if extension occurs.
Waveform files can be of type .wfm, .csv, .txt, .wiq, .bin, .mat, .hdf, .h5, or .bnd. See Supported File Formats below. The file must exist on the instrument’s disk or a mapped network drive (NV or SNV memory); the file cannot be in the instruments volatile memory (SWFM).
Waveforms must be a minimum of 1024 samples and, for the M9384B, the samples must be a multiple of 16.
Use the File Select button to navigate to the file browser.
Within the file browser, select the desired waveform file.
Attempting to use an inappropriate waveform file will result in an error when the file is actually used, not necessarily when the waveform file is selected via the Select button.
File names and file paths must comprise ASCII characters only. Otherwise, a "File name not found" error occurs. In addition, a file name cannot contain a comma or a semicolon.

In use cases where the modulated signal contains component carriers that are spectrally separated within the Occupied Bandwidth, you can specify the Aggregate Active Bandwidth to indicate the how the RF energy is distributed within the Occupied Bandwidth. For example, if you have a two component carrier signal with each carrier 5 MHz wide, spaced 100 MHz apart on center, the Occupied Bandwidth will be 105 MHz and you would set the Aggregate Active Bandwidth to 10 MHz. The Aggregate Active Bandwidth is never greater than the Occupied Bandwidth. Appropriately specifying the Aggregate Active Bandwidth and Occupied Bandwidth may improve the ACPR and EVM performance of the instrument. View image of example frequency domain.

Marker routing applies to the Waveform File and Real-Time signal modes.
SCPI commands directly tied to this GUI are not defined, rather the event connectors SCPI commands are used to setup the marker routine.
Some Vector Modulation Signal Modes provide a mechanism to output a TTL-like signal synchronized with the modulation playback. Depending on the capability provided by the instrument, up to four markers can be provided. See Waveform Header.
For the M9484C, a Marker can be routed to three Event connectors of the instrument:

Marker routing applies to the Waveform File signal mode.
Some Vector Modulation Signal Modes provide a mechanism to output a TTL-like signal synchronized with the modulation playback. Depending on the capability provided by the instrument, up to four markers can be provided. See Waveform Header.
For M9383B and M9384B, a marker can be routed to the instrument’s internal functions of ALC Hold and RF Blanking, and to the Sync connector for synchronizing external equipment with the modulation playback.
For channel bonding configurations, note the following:
For marker related outputs when in the Bonded Configuration, use the physical connectors on Channel-1. The behavior of connectors for Channel-2 are undefined and should not be used for the bonded configurations.
The bonding process generates the marker data for the bonded waveform based on the marker data of the waveform file provided. Because of this, the marker data cannot be edited after performing the bonding process. Thus, the marker data of the waveform file must be set up first.
ALC and RF Blanking markers are not supported by the bonding process, or for playback when in the bonded configuration. Thus, the Sync output is the appropriate marker for bonded configuration.
Use Signal 1 for SCPI commands when configuring the markers.
Marker Routing for ALC Hold applies only to the M9383B VXG-m and the M9384B VXG.
Enables the marker ALC hold function for the selected marker. Use the ALC hold function when you have a waveform signal that incorporates idle periods, or when the increased dynamic range encountered with RF blanking is not desired. The ALC leveling circuitry responds to the marker signal during the marker pulse (marker signal high), averaging the modulated signal level during this period.
The ALC hold function operates during the low periods of the marker signal.
NONE: This terminates the marker ALC hold function.
M1–M4: These are the marker choices. The ALC hold feature uses only one marker at a time.
Incorrect automatic level control (ALC) sampling can create a sudden unleveled condition that may create a spike in the RF output potentially damaging a DUT or connected instrument. Ensure that you set markers to let the ALC sample over an amplitude that accounts for the high power levels within the signal.

This command creates a waveform sequence. A waveform sequence is made up of waveform files and/or other sequences. Any number of waveform files can be used to create a sequence (within capacity of the file system). The max number of repetitions is 65535.
The query returns the contents and segment settings of the waveform sequence file.
The waveform files and/or sequences play in the same order as placed into the waveform sequence by the command. Once you create the file, you cannot edit the segment settings or add further waveform segments. Using the same waveform sequence name overwrites the existing file with that name.
The parameters of the command are as follows:
"<file name>": The name given to the waveform sequence file. The <file name> can be specified as a full or relative path, or using MSUS "SEQ<channel>:file name".
"<waveform1>": Specifies the name of an existing waveform or sequence file. The file must reside in volatile memory, WFM. This will be the first waveform or sequence in the newly created sequence <file name>.
<reps1>: This variable sets the number of times <waveform1> plays (repeats) before the next segment plays.
"<waveform2>": Specifies the name of an existing waveform or sequence file. The same conditions required for waveform1 apply for this waveform or sequence. This will be the second waveform or sequence in the newly created sequence <file name>.
<reps2>: This variable sets the number of times <waveform2> plays (repeats).

When a sequence file is played and waveform segments in the sequence file are missing from the ARB memory, the VXG signal generator tries to upload them. If the sequence file is in the default folder for sequence files, the default folder for waveform files is checked. Otherwise, the folder where the sequence file is located is checked first, and then the default folder for waveform files is checked. The following files in the folder are checked for a segment <waveform>:
If <waveform> contains a file extension, <waveform>
Otherwise, the VXG signal generator tries to upload the following files in this order:
<waveform> as a secure waveform file

Assume that there are MyWaveform1.wfm (Keysight Signal Studio waveform), MyWaveform2.wiq (binary waveform) and MyWaveform3.csv (csv waveform) under <Documents>\Keysight\PathWave\SignalGenerator\Waveforms. The following SCPI listings upload the waveform data from non-volatile memory to the arb memory and create waveform sequences.
From version A.03.00, :MMEMory:COPY can be omitted when the waveform is in the predefined folder because the file not found in the ARB memory is automatically uploaded from the non-volatile memory. Also, MSUS in the waveform parameters of :MEMory:DATA:SEQuence is not required. When used, it is ignored. For example:
:MEMory:DATA:SEQuence "SEQ:MySequence", "SWFM1:MyWaveform1", 10, ALL, "SWFM1:MyWaveform2", 100, ALL
is the same as
:MEMory:DATA:SEQuence "SEQ:MySequence", "MyWaveform1", 10, ALL, "MyWaveform2", 100, ALL
because SWFM1: is ignored.
In this example the first waveform is played 10 times and then the second waveform is played 100 times.

This is an example of a nested sequence. The first sequence will be named "BaseSequence" and consists of "MyWaveform1.wfm" repeated 10 times followed by "MyWaveform2.wiq" repeated 100 times. Then sequence named "MySequence" is created wherein "BaseSequence" will be repeated twice followed by "MyWaveform3" repeated 30 times. When "MySequence" is selected as waveform, segments played are as follows:
"MyWaveform1.wfm" 10 times
"MyWaveform2.wiq" 100 times
"MyWaveform1.wfm" 10 times
"MyWaveform2.wiq" 100 times

Additive white Gaussian noise (AWGN) is a basic noise node for thermal noise in communication channels. The modifiers denote specific characteristics:
Additive is added to any noise that might be intrinsic to the information system.
White has uniform to power across the frequency band for the information system. That is, the power spectral density is flat, so the auto correlation of the noise in the time domain is zero for any non-zero time offset.
Gaussian has a normal distribution in the time domain with an average time domain value of zero.
Sets the channel bandwidth over which the AWGN is applied. The channel bandwidth is the portion of the bandwidth specified by the bandwidth ratio.
