86 Relay Driver Module Command Reference
The TRIGger command subsystem controls the triggering operation of a Relay
Driver Module in a switchbox.
TRIGger
[:IMMediate]
:SOURce <source>
:SOURce?
Causes a trigger event to occur when the defined trigger source is
TRIGger:SOURce BUS or TRIGger:SOURce HOLD. This can be used to trigger a
suspended scan operation.
•
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] will execute.
•
BUS or HOLD Source Remains: If selected, the TRIGger:SOURce BUS
or TRIGger:SOURce HOLD commands remain in effect after triggering a
switchbox with the TRIGger[:IMMediate] command.
•
Related Commands: INITiate, [ROUTe:]SCAN, TRIGger:SOURce
Example: Advancing Scan Using TRIGger
This example uses the TRIGger command to advance the scan of a single-module
switchbox from channel 00 through 03. Since TRIGger:SOURce HOLD is set, the
scan is advanced one channel each time TRIGger is executed.
TRIG:SOUR HOLD
SCAN (@100:103)
INIT
loop statement
TRIG
increment loop
