Set the phase deviation in degrees. This value represents the peak variation
in phase of the modulated waveform from the carrier waveform. Select any
value from 0 to 360 degrees. The default is 180 degrees. MIN = 0 degrees.
MAX = 360 degrees. The :PM[1|2]:DEV? query returns the phase
deviation in degrees. If you select the External modulating source
(PM[1|2]:SOUR EXT command), the deviation is controlled by the
±2.5V/±5V signal level present on the rear panel Modulation In connector.
For example, if you have set the frequency deviation to 180 degrees, then a
+2.5V/+5V signal level corresponds to a 180 degree phase deviation. Lower
external signal levels produce less deviation, and negative signal levels
produce a negative phase shift.
