[:SOURce<hw>]:PM:SOURce <Source>

Selects the modulation signal source for phase modulation.

You can use both, the internal and an external modulation signal at a time.

Parameters:
<Source>
INTernal| EXTernal | INT,EXT | EDIGital
INTernal

Uses the internally generated signal for modulation. To configure the LF signal, use the commands of the "SOURce:LFOutput Subsystem" subsystem.

With command [:SOURce<hw>]:PM:INTernal:SOURce you can select the internal signal source.

EXTernal

Uses an externally applied modulation signal.

INT,EXT

Uses both, the internal and external modulation signals.

EDIGital

Uses an externally applied digital modulatioin signal.

*RST:INT
Example: PM:SOUR INT

selects the internal modulation source.

Options: Option R&S SMA-B20 or R&S SMA-B22
Manual operation: See "ɸM Source"
