Pm[1]|2[:Deviation]; Pm[:Deviation]:Step[:Increment] - Keysight N5171B EXG Manual

Analog Modulation Commands
Phase Modulation Subsystem–Option UNT ([:SOURce])

:PM[1]|2[:DEViation]

[:SOURce]:PM[1]|2[:DEViation] <value><unit>|UP|DOWN
[:SOURce]:PM[1]|2[:DEViation]?
This command sets the deviation of the phase modulation.
The variable <unit> will accept RAD (radians), PIRAD (pi-radians), and DEG
(degrees); however, the query will only return values in radians.

:PM[:DEViation]:STEP[:INCRement]

[:SOURce]:PM[:DEViation]:STEP[:INCRement] <value><unit>
[:SOURce]:PM[:DEViation]:STEP[:INCRement]?
This command sets the phase modulation deviation step increment.
