Programming The Instrument Trigger Modes - HP 81101A Reference Manual

Programming the Instrument
Trigger Modes
The following figure shows the instrument's arming/triggering model:
:ARM Event detection layer
:ARM:SOURce IMMediate (Internal VFO)
INTernal2 (Internal PLL)
EXTernal (EXT INPUT)
Manual (MAN key)
:TRIGger Event detection layer
:TRIGger:SOURce IMMediate (Internal VFO)
INTernal2 (Internal PLL)
EXTernal2 (CLK IN)
:TRIGger:COUNt n
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
panel.
