[: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:
<Sensitivity> float
Example:
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.
Usage: Query only
SCPI confirmed
[:SOURce<hw>]:PM:SOURce <Source>
The command selects the modulation source for phase modulation.
Parameters:
<Source> INTernal | EXTernal | INT,EXT
INTernal
INT is the LF generator. The frequency of the internal modulation
signal can be set in the SOURce:LFOutput subsystem.
EXTernal
The external signal is input at the EXT MOD connector.
INT,EXT
Internal and external modulation source can be selected at the
same time.
*RST: INTernal
Example:
PM:SOUR INT
selects the internal modulation source.
Usage: SCPI confirmed
[:SOURce<hw>]:PM:STATe <State>
The command activates/deactivates phase modulation. Activation of phase modulation
deactivates frequency modulation.
Parameters:
<State> 0 | 1 | OFF | ON
*RST: OFF
SOURce Subsystem
