[SOURce[1]]:PM:SOURce
<frequency>::=<NRf>[<units>]
where:
<NRf> is the modulation frequency.
<units>::=[Hz | kHz | MHz]
<frequency>
SOURce1:PM:INTernal:FREQuency 10kHz
sets the CH 1 internal modulation frequency to 10 kHz.
This command sets or queries the modulating waveform of PM modulation for the
specified channel. You can use this command only when the internal modulation
source is selected.
If you specify EFILe when there is no EFILe or the EFILe is not yet defined,
this command causes an error.
