TRIGger

The TRIGger subsystem controls the triggering operation of RF multiplexer 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] will be executed.

HOLD or BUS Source Remains: The TRIGger:SOURce HOLD or

TRIGger:SOURce BUS commands remain in effect, if selected, after triggering a 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 03. 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 (@100:103)

! 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
