[:SOURce<hw>]:PM:SENSitivity?
The command queries the input sensitivity of the EXT MOD input in RAD/V. The com-
mand is only effective if the external modulation source is selected (SOUR:PM:SOUR
EXT). The returned value depends on the modulation deviation setting
(SOUR:PM:DEViation). This value is assigned to the voltage value for full modulation
of the input.
Return values:
float<Sensitivity>
PM:DEV 1
sets a modulation deviation of 1RAD.
PM:SENS?
queries the input sensitivity at the EXT MOD input.
Response: 1
since the voltage value for full modulation is 1V, the resulting sen-
sitivity is precisely 1RAD/V.
Example:

Usage:
[:SOURce<hw>]:PM:SOURce <Source>
The command selects the modulation source for phase modulation. INT is the LF gen-
erator. The frequency of the internal modulation signal can be set in the SOURce:LFOut-
put subsystem. The external signal is input at the EXT MOD connector. Internal and
external modulation source can be selected at the same time.

[:SOURce<hw>]:PM:STATe <State>
The command activates/deactivates phase modulation. Activation of phase modulation
deactivates pulse modulation
