Phase Modulation subsystem ([:SOURce])
Chapter 4 277
:PM[1]|2[:DEViation]
Supported PSG-A Series
[:SOURce]:PM[1]|2[:DEViation] <val><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.

Key Entry
ΦM Dev
Remarks If deviation tracking is active, a change to the deviation value on one
path will apply to both.
Refer to “:PM[:DEViation]:STEP[:INCRement]” on page 278 for setting
the value associated with the UP and DOWN choices.
