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
