Vector Modulation Bandwidth Limitations

The vector modulation bandwidth is based on the instrument’s optional capabilities and operating settings. The bandwidth is as follows:

Table: N5186A MXG Vector Modulation BW

Operating Settings		Bandwidth Options
Operating Settings		R10	B9X	B5X	B2X
Max Sample Rate (MHz)		1200	1200	600	300
Max Bandwidth (MHz)		1000	1000	500	250
Modulation Bandwidth (MHz)	9 kHz <= f <= 5.75 GHz	1000	1000	500	250
	5.75 GHz < f <= 31.25 GHz	1000	1000	500	250
	31.25 GHz < f <= 31.838 GHz	1000	1000	500	250
	31.838 GHz < f < 36.962 GHz	1000	1000	500	250
	36.962 GHz <= f < 37.55 GHz	1000	1000	500	250
	37.55 GHz <= f < 89.05 GHz	1000	1000	500	250
	89.05 GHz <= f	1000	1000	500	250

If your configuration exceeds the available bandwidth, the following message appears in the Notifications Area:

Modulation BW is greater than instrument’s BW (<bandwidth>) at this frequency

In this scenario, you may operate the instrument with the resulting performance, or reduce the modulation setting to resume operation within the available bandwidth, as determined by the Mode in use.

Enable

Turns vector modulation signal on and off.

When I/Q Modulation Source is Internal, toggling this setting also toggles I/Q Modulation On to the same state.

Notes	If using floating licenses, be sure to query "SYST:ERR?" after attempting to set "SIGN ON"; if the license was not obtained from the server the error -310,"System error; feature not licensed" is returned.
Preset	OFF
Coupling	When Enable Vector Modulation is set to On, if I/Q Output Amplitude Control is ON, no coupling occurs; meaning the current state of Output Modulation I/Q is unchanged and Output Modulation I/Q Source is unchanged. When Enable Vector Modulation is set to On, if I/Q Output Amplitude Control is OFF, if Output Modulation I/Q Modulation Source is Internal, the I/Q Modulation state is set to ON. When the Loaded Application is empty or the Signal's Application doesn't match the Loaded Application, Enable Vector Modulation Signal is set to OFF and is not changeable.
State Saved	No When the mode is real-time, when recalling, the state is Off as real-time internal settings are not ready after recall/preset. When the mode is ODI Streaming, when recalling, the state is Off as ODI Streaming should be turned On after checking that the hardware is ready.

Analysis

Click this button to access the Analysis screen which provides the complementary cumulative distribution function (CCDF) measurement for a given signal or file.

The CCDF measurement is a statistical power measurement that indicates the probability of a signal power reaching or exceeding a given power value. CCDF represents the complement of the cumulative distribution function (CDF) that is, CCDF = 1 – CDF.

GUI Location

Signals > General tab > Analysis

Each measurement can be defined as follows:

CDF = Probability(x < K)
CCDF = Probability(x ≥ K)

The Signal Generator application visualizes the CCDF curve with probability (%) on the y-axis and power (dB) on the x-axis. Power on the x-axis is relative to the average signal power, so 0 dB is the average power of the signal. As an example, a value of 2 dB and 12% on the curve indicates that there is a 12% probability that the signal power will reach 2 dB or more above the average power.

Behind the CCDF curve, another line is drawn to represent the Gaussian noise CCDF reference.

Reset Phase Accumulator

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.

Trigger

Trigger Mode

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 N5186A. The trigger controls the segment advance within a waveform sequence. To use this choice, a waveform sequence must be the active waveform.

Continuous Mode

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.
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.

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.	N5186A

KEY and BUS 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.

Tips for N5182B MXG backward compatibility:

On N51xxB, 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 N51xxB. The following table shows returned values of Trigger Source and Continuous Mode in N51xxB and this instrument when the SCPI commands are sent in the following order. The user from N51xxB should understand the behavior difference.

Multitone

This capability requires license model E7621APPC.

Number of Samples of a Multitone Signal

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 ( 6.4 M samples for N5186A). In this case, an error is issued, and Multitone signal is not generated. Also, if the tone spacing is changed to a non-integer value, as the number of samples is expected to be greater than the internal buffer array, an error is issued, and Multitone signal is not generated.

If the tone spacing is changed to 12,111,000 Hz, the GCD becomes 1 kHz and the signal length will reduce to 0.001 sec. It is 2.56 M samples and small enough to fit in the buffer.

Setup

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 query returns the name of either the most recently used file in this command or the most recently exported tone table file.

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 is 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.

Noise Power Ratio (NPR)

Noise Power Ratio (NPR) settings can be used to create notches (= to turn off the states of tones). When we have tones with tone spacing , Noise Bandwidth can be calculated with . At the -th notch, the relationship between Relative Width (%) and Absolute Width (Hz) is defined as and the relationship between Relative Center (%) and Absolute Center (Hz) is also defined as . At the -th tone, when is satisfied, the state of the tone is turned off.

The region includes the border line (see the 1^st notch). Also, the border is not required to set the same frequency of the tone (see the 2^nd notch).
Multiple notches can be overlapped (see the 3^rd and the 4^th notches).
Notch can be defined for out of the noise BW (see the 5^th notch).

Waveform File

File

N5186A MXG (view image)

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.

See Supported File Formats.

Arb memory is also utilized by various internal processes. Therefore, you may see files in this folder that you have not explicitly uploaded.

Edit in App

If you use an embedded application (e.g. 5G NR, Custom Modulation) to configure and generate a waveform, clicking Generate automatically saves the waveform configuration as a metadata file along with the generated waveform file. Then whenever the waveform is selected from the Signal Setup screen, the Edit in App button appears next to the File field, providing easy access to the appropriate application with the configuration used to generate this waveform.

Supported File Formats

Format	File Extension	Description
Signal Studio	*.wfm	Waveforms exported from Keysight Signal Studio applications.
Keysight 16-bit binary	.wiq .bin *.WAVEFORM	Contains interleaved I/Q samples (I0, Q0, I1, Q1, …). Values must be stored in 16-bit signed integers. The Default Binary File Format can be set to either Big Endian or Little Endian. See Keysight 16-Bit Binary in the Creating and Downloading Waveforms tutorial.
ASCII	.csv .txt	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.
Sequence	*.seq	Created by Keysight signal generators.
MATLAB	*.mat	The MAT file format (version 4, 6, 7, and 7.3) and the HDF5 format are supported. See MATLAB in the Creating and Downloading Waveforms tutorial.

Waveform Header

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 Waveform File 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.

Header Save

This command takes the current settings for the selected waveform file and saves them to the header file for the waveform. A waveform file must be selected for this command to function. The settings saved in the header are:

Occupied Bandwidth
RMS Power
Sample Rate
Scale

MSUS Examples

The following table shows MSUS examples.

SCPI command example	File
GRO:SIGN:WAV "SNVWFM:abc"	Waveforms\abc.wfm
GRO:SIGN:WAV "NVWFM:abc"	Waveforms\abc.wiq
GRO:SIGN:WAV "SWFM1:abc"	Waveform "abc" in Ch1 ARB memory
GRO:SIGN:WAV "WFM1:abc"	Waveform "abc" in Ch1 ARB memory
GRO:SIGN:WAV "SWFM2:abc"	Waveform "abc" in Ch2 ARB memory

Please note that there is no MSUS for .bin extension. To select a .bin file, relative or absolute path can be used as shown below.

GRO:SIGN:WAV "abc.bin"

Auto Folder Selection by Extension

Auto folder selection works for this setting in the same way as memory commands, defined in the ARB Waveform Memory topic. See also File Location and Default Folders 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 in the following folder as a location of waveform file:

Waveforms\

If the extension is not supported by Auto Folder Selection, the file path is the top level of the file system.

The following table shows some of waveform file path examples and which folders are selected.

SCPI command example	Folder
GRO:SIGN:WAV "abc.wfm"	Waveforms\
GRO:SIGN:WAV "myDir\abc.wfm"	Waveforms\myDir
GRO:SIGN:WAV "C:\wfm\abc.wfm"	Not applicable, an error will be generated
GRO:SIGN:WAV "abc.wiq"	Waveforms\
GRO:SIGN:WAV "abc.bin"	Top level of file system
GRO:SIGN:WAV "abc.csv"	Top level of file system
GRO:SIGN:WAV "Waveforms\abc.bin"	Waveforms\

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"	States\
GRO:SIGN:WAV "..\abc.sgen"	Top level of file system

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 MXG 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.

Nonlinear Correction

Allows you to configure and set the nonlinear correction for the signal. By default, it is set to Off.

When you select a waveform file, the Configure button is enabled that allows you to configure the nonlinear correction.

The instrument provides the following type of nonlinear correction using the Digital Predistortion (DPD) technique.

AWGN

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.

Channel Bandwidth

Sets the channel bandwidth over which the AWGN is applied. The channel bandwidth is the portion of the bandwidth specified by the bandwidth ratio.
