Trigger Modes
The following figure shows the instrument’s arming/triggering model:
You program the comprehensive triggering capabilities of the instrument
using the SCPI :ARM and :TRIGger subsystems. Using these two
command subsystems you can program the operating modes of the
instrument, which are set up using the M
