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
