PM:SOURce

[SOURce]:PM:SOURce EXTernal|LFGenerator
[SOURce]:PM:SOURce?
This command selects the PM modulation signal source. If LFGenerator is selected, the
device’s function output has to be connected to the FM/PM input (at the rear panel).
*RST EXT

:

PM:STATe

[SOURce]:PM:STATe ON|OFF|1|0
[SOURce]:PM:STATe?
This command turns the phase modulation on or off.
*RST OFF

[SOURce]:PULM Subsystem (Pulse Modulation)

This additional functionality provides pulse modulation of the RF output signal delivered
to the load by an internal or external modulation signal. The INTernal selection accesses
the internally generated modulation input while EXTernal selects the external pulse (rear
panel connector) input.
