Arb Commands
Dmodulation Subsystem–N5172B/82B with Option 431 ([:SOURce]:RADio:DMODulation:ARB)
:PHASe:NOISe:F1
Supported
N5172B/82B with Option 431 and 432
[:SOURce]:RADio:DMODulation:ARB:PHASe:NOISe:F1 <value
><unit>
[:SOURce]:RADio:DMODulation:ARB:PHASe:NOISe:F1?
This command sets the start 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
:PHASe:NOISe:F2
). If the
value is set greater than the stop frequency value, the signal generator resets the stop value to equal
the start value.
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

Range
0 Hz to 77.50052449 MHz
Key Entry
Desired Start Freq (f1)
:PHASe:NOISe:F1:ACTual?
Supported
N5172B/82B with Option 431 and 432
[:SOURce]:RADio:DMODulation:ARB:PHASe:NOISe:F1:ACTual?
This query 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.
:PHASe:NOISe:F2
Supported
N5172B/82B with Option 431 and 432
[:SOURce]:RADio:DMODulation:ARB:PHASe:NOISe:F2 <value
><unit>
[:SOURce]:RADio:DMODulation:ARB: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
:PHASe:NOISe:F1
). 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.
