Trigger Modes

The following figure shows the instruments arming/triggering model:


*RST or power on			Idle
*RST or power on			Idle

Trigger system

initiated(1)

no longer initiated(1)

Initiated

(still) initiated(1)

ARM conditions

satisfied

wait for Arm

completed # of Trigger

loops(2)

or

no longer initiated

wait for Trigger

Notes:

(1)	The instrument is always initiated in CONTINUOUS modes.
	The instrument is automatically initiated in MANual started/gated modes.
(2)	1 in Pulses Mode (same as :TRIGger:COUNt)
	:TRIGger:COUNt in Continuous/Gated Mode
	Maximum of :TRIGger:COUNt:PULSes1 and :TRIGger:COUNt:PULSes2
	in Started Burst mode

Trigger conditions

satisfied

Depends on sequence in Pattern Mode (may be infinite)

For details of the	You program the comprehensive triggering capabilities of the instrument
trigger count	using the SCPI :ARM and :TRIGger subsystems. Using these two
command, refer to	command subsystems you can program the operating modes of the
“:TRIG:COUN” on	instrument which are set up using the MODE/TRG screen on the
page 89.	frontpanel.
	Use the :ARM subsystem to select the overall triggering mode of the
	instrument (CONTINUOUS, STARTED, GATED), and the :TRIGger
	subsystem to select the pulse period source, triggering and number of
	pulse periods per :ARM event (BURST length). In pattern mode the
	pattern length is the sum of each used segments length.
