Scanning Using Bus Triggers

This example uses bus triggering (TRIG:SOUR BUS) to scan channels 00 through 02 of a single-module switchbox. The trigger source to advance the scan is the *TRG command (as set with TRIGger:SOURce BUS). When INIT is executed, the scan is started and channel 00 is closed. Then, each *TRG command advances the scan to the next channel.

TRIG:SOUR BUS	Select interface (BUS) triggering.
SCAN (@100:102)	Scan channels 00 through 02.
INIT	Start scan, close channel 00.
*TRG	Advances scan using BUS
	triggering.
increment loop	Increment loop count.

:SOURce? TRIGger:SOURce? returns the current trigger source for the switchbox. Command returns either BUS, EXT, HOLD, or IMM for trigger sources BUS, EXTernal, HOLD, or IMMediate, respectively.

Example Query the Trigger Source

TRIG:SOUR EXT	Sets trigger source to external.
TRIG:SOUR?	Query trigger source.
