TRIGger
The TRIGger subsystem commands controls the triggering operation of the
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 in the [ROUTe:]SCAN <channel_list>command
and an INITiate:IMMediate command must be executed before
TRIGger:IMMediate can trigger the switchbox.
• HOLD or BUS Source Remains: If selected, the
TRIGger:SOURce HOLD or TRIGger:SOURce BUS commands
remain in effect, after triggering the switchbox with the
TRIGger[:IMMediate] command.
• Related Commands: INITiate, [ROUTe:]SCAN.
Example Advancing Scan using the TRIGger Command
TRIG:SOUR HOLD Sets trigger source to hold
SCAN (@100:147) Sets channel list
INIT Starts scanning cycle
loop statement Start count loop
TRIG Advances channel list
increment loop Increment count loop
:SOURce TRIGger:SOURce BUS |EXTernal |HOLD |IMMediate specifies the trigger
source to advance the channel list during scanning.

Comments
•
Enabling the Trigger Source: The TRIGger:SOURce command
only selects the trigger source. The INIT[:IMMediate] command
enables the trigger source.
• Using the TRIG command: You can use the
TRIGger[:IMMediate] command to advance the scan when
TRIGger:SOURce BUS or TRIGger:SOURce HOLD is selected.
