Set Trigger Source to AM for FSMR

Question

I want to set the trigger source of my FSMR to AM. But it always sets the trigger source to RF level.

How can I set the trigger source to AM ?

Answer

TRIG:SOUR AM is the trigger setting for RF level (historical reasons).

The correct command for AM mod trigger is TRIG:SOUR AMR (for AM relative)

The level setting is then TRIG:LEV:AM:REL 30 for 30%, no unit is required
