Digital:data:input:phase:noise:f1:Actual; Digital:data:input:phase:noise:f2 - Keysight N5171B EXG Manual

Digital Signal Interface Module Commands
Digital Subsystem—Option 003 and 004 ([:SOURce])
The actual value may vary logarithmically depending on the value of the stop
frequency. This behavior is more noticeable at higher frequency values. For
more information, see the User's Guide.
The phase noise is added to the base phase noise of the instrument.

:DIGital:DATA:INPut:PHASe:NOISe:F1:ACTual?

:DIGital:DATA:INPut:PHASe:NOISe:F1:ACTual?
This SCPI command returns the actual f1 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 f1 is varied, based on the capabilities of the hardware.

:DIGital:DATA:INPut:PHASe:NOISe:F2

:DIGital:DATA:INPut:PHASe:NOISe:F2 <value><unit>
:DIGital:DATA:INPut:PHASe:NOISe:F2?
This command sets the stop frequency value of the flat area for the phase noise
impairment.
Ensure that this value is less than or equal to the stop frequency value (see the
:DIGital:DATA:INPut:PHASe:NOISe:F1 command). If the value is set less than
the start frequency value, the signal generator resets the start value to equal
the stop value.
The actual value may vary logarithmically, which is more noticeable at higher
frequency offset values. For more information, see the User's Guide.
The phase noise is added to the base phase noise of the instrument.
