Real–Time Commands
Custom Subsystem–Option 431([:SOURce]:RADio:CUSTom)
:PHASe:NOISe[:STATe]
Supported N5172B/82B with Option 431 and 432
[:SOURce]:RADio:CUSTom:PHASe:NOISe[:STATe] ON|OFF|1|0
[:SOURce]:RADio:CUSTom:PHASe:NOISe[:STATe]?
This command turns the phase noise impairment on or off. For more information on the phase noise
impairment option, see the User’s Guide.
*RST 0
Key Entry Phase Noise Off On
:PHASe:NOISe:TRACe?
Supported N5172B/82B with Option 431 and 432
[:SOURce]:RADio:CUSTom:PHASe:NOISe:TRACe? <startFreq>,<stopFreq>,<numSamples>
This query returns the theoretical phase noise amplitude mask applied with the current settings if
the phase noise feature is on. This mask does not take the natural phase noise of the instrument into
account, only the impairment from the phase noise feature. The output is over the start frequency to
the stop frequency for the number of samples specified. The samples are taken at logarithmic
frequency steps and the output is in dBc/Hz.
:POLarity[:ALL]
Supported N5172B/82B with Option 431
[:SOURce]:RADio:CUSTom:POLarity[:ALL] NORMal|INVerted
[:SOURce]:RADio:CUSTom:POLarity[:ALL]?
This command sets the rotation direction of the phase modulation vector.
NORMal
This choice selects normal phase polarity.
INVerted This choice inverts the internal Q signal.
*RST NORM
Key Entry Phase Polarity Normal Invert
:RETRigger
Supported N5172B/82B with Option 431
[:SOURce]:RADio:CUSTom:RETRigger ON|OFF|1|0|IMMediate
[:SOURce]:RADio:CUSTom:RETRigger?
This command enables or disables the ARB retriggering mode. The retrigger mode controls how the
retriggering function performs while a waveform is playing.
ON (1) This choice (Buffered Trigger) specifies that if a trigger occurs while a waveform
Range <startFreq> 1 Hz to 100 MHz
<stopFreq> 1 Hz to 100 MHz
<numSamples> 1 to 8192
