The trigger subsystem is used to synchronize device action(s) with events or
in other words you program the comprehensive triggering capabilities of the
instrument using the SCPI:ARM and :TRIGger subsystem. Using these
two command subsystems you can program the operating modes of the
instrument. More precise use the :ARM subsystem to the select the overall
triggering mode of the instrument e.g. Continuous, External triggered, Gated,
etc. and the trigger subsystem to select for example the number of pulse
period. The following diagram illustrates the trigger model of 81150A /
81160A.
