[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.
