Real–Time Commands
Phase Noise Subsystem–Option 432 ([SOURce:RADio:PHASe:NOISe)

:LMID:ACTual?

[:SOURce]:RADio: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.

[:STATe]

[:SOURce]:RADio:PHASe:NOISe[:STATe] ON|OFF|1|0
[:SOURce]:RADio: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.

:TRACe?

[:SOURce]:RADio: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.
