338Operating Manual 1407.0806.32 ─ 13
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
Manual operation: See "PhiM Sensitivity" on page 178
[:
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 MOD EXT 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.
Manual operation: See "PhiM Source" on page 176
[: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
Example:
PM:STAT ON
activates PM modulation.
Manual operation: See "State" on page 176
