TRIGger

	The TRIGger subsystem controls the triggering operation of the Microwave
	Switch modules in a switchbox.
Subsystem Syntax	TRIGger
	[:IMMediate]
	:SOURce BUS EXTernal HOLD IMMediate
	:SOURce?
[:IMMediate]	TRIGger[:IMMediate] causes a trigger to occur when the defined trigger
	source is TRIGger:SOURce HOLD or TRIGger:SOURce BUS.
Comments	∙ Executing the TRIGger[:IMMediate] Command: A channel list
	must be defined with [ROUTe:]SCAN <channel_list> and an
	INITiate[:IMMediate] command must be executed before
	TRIGger[:IMMediate] can trigger the switchbox.
	∙ HOLD or BUS Source Remains: If selected, the TRIGger:SOURce
	HOLD or TRIGger:SOURce BUS commands remain in effect after
	triggering the switchbox with the TRIGger[:IMMediate] command.
	∙ Related Commands: INITiate, [ROUTe:]SCAN
Example Advancing Scan Using the TRIGger Command
	This example uses the TRIGger command to advance the scan of a
	single-module switchbox from channel 00 through 02. Since
	TRIGger:SOURce HOLD is set, the scan is advanced one channel each time
	TRIGger is executed.
	TRIG:SOUR HOLD	Sets trigger source to HOLD.
	SCAN (@100:202)	Defines channel list.
	INIT	Begin scan, close channel 00.
	loop statement	Start count loop.
	TRIG	Advance scan to next channel.
	increment loop	Increment loop count.
:SOURce	TRIGger:SOURce BUS EXTernal HOLD IMMediate specifies the
	trigger source to advance the channel list during scanning.
Parameters

	Parameter Name	Parameter Type		Range of Values


	BUS	discrete		*TRG command

	EXTernal	discrete		Event In BNC port

	HOLD	discrete		Hold triggering

	IMMediate	discrete		Continuous triggering
