Example Scanning Using External Triggers

This example uses external triggering (TRIG:SOUR EXT) to scan channels 00 through 03 of a single-module switchbox. The trigger source to advance the scan is the input to the “ Event In” BNC on an HP E1 300A/E1301A mainframe. When INIT is executed, the scan is started and channel 00 is closed. Then each trigger received at the “ Event In” BNC advances the scan to the next channel.

TRIG:SOUR EXT	! Select external triggering
SCAN (@100:103)	! Scan channels 00 through 03
INIT	! Begin scan, close channel 00
trigger externally	! Advance scan to next channel

Example Scanning Using Bus Triggers

This example uses bus triggering (TRIG:SOUR BUS) to scan channels 00 through 03 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 (@100:103)	! Scan channels 00 through 03
INIT	! Start scan, close channel 00
loop statement	! Loop to scan all channels
*TRG	! Advance 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 Trigger Source

This example sets external triggering and queries the trigger source. Since external triggering is set, TRIG:SOUR? returns "EXT".

TRIG:SOUR EXT	! Set external trigger source
TRIG:SOUR?	! Query trigger source
