Agilent X-Series Signal Generators SCPI Command Reference 339
Arb Commands
Two Tone Subsystem–N5172B/82B ([:SOURce]:RADio:TTONe:ARB)
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 the :PHASe:NOISe:F2
command). 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.
*RST +1.00000000E003
Range 0 Hz to 77.50052449 MHz
Key Entry Desired Start Freq (f1)
:PHASe:NOISe:F1:ACTual?
Supported N5172B/82B with Option 432
[:SOURce]:RADio:TTONe: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 432
[:SOURce]:RADio:TTONe:ARB:PHASe:NOISe:F2 <value><unit>
[:SOURce]:RADio:TTONe: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 the :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.
*RST +3.00000000E+004
Range 1 Hz to 77.50052449 MHz
Key Entry Desired Stop Freq (f2)
:PHASe:NOISe:F2:ACTual?
Supported N5172B/82B with Option 432
[:SOURce]:RADio:TTONe:ARB:PHASe:NOISe:F2:ACTual?
This query returns the actual f2 in use with the current set of desired values. This value may or may
not vary if the desired f2 value is changed, based on the capabilities of the hardware.
