Phase:noise:lmid:actual; Phase:noise[:State]; Phase:noise:trace - Agilent Technologies N5171B Command Reference Manual

Arb Commands
Multitone Subsystem–N5172B/82B ([:SOURce]:RADio:MTONe:ARB)
NOTE The amplitude range varies depending on the f2 value
f2 increases in value, the range for Lmid decreases. If the current Lmid setting is too high
for the new f2 value, the signal generator changes the Lmid value and generates an error.
The range values are expressed in units of dBc/Hz.

:PHASe:NOISe:LMID:ACTual?

Supported N5172B/82B with Option 432
[:SOURce]:RADio:MTONe:ARB:PHASe:NOISe:LMID:ACTual?
This query returns the actual Lmid in use with the current set of desired values. This value may vary
if the desired f2 value is changed, and may or may not vary when Lmid is varied, based on the
capabilities of the hardware.

:PHASe:NOISe[:STATe]

Supported N5172B/82B with Option 432
[:SOURce]:RADio:MTONe:ARB:PHASe:NOISe[:STATe] ON|OFF|1|0
[:SOURce]:RADio:MTONe:ARB: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.

:PHASe:NOISe:TRACe?

Supported N5172B/82B with Option 432
[:SOURce]:RADio:MTONe:ARB: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.
