TRIGger
The TRIGger subsystem commands control the triggering operations of the
multiplexer switchbox.
Subsystem Syntax TRIGger
[:IMMediate]
:SOURce <
source>
:SOURce?
[:IMMediate] TRIGger[:IMMediate] executes a trigger when the defined trigger source is
TRIGger:SOURce HOLD or TRIGger:SOURce BUS. Note that
TRIGger[:IMMediate] is NOT the same as TRIGger:SOURce IMMediate.
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] 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 (@100:107) Sets channel list.
INIT Starts scanning cycle.
loop statement Start count loop.
TRIG Advances scan to next channel.
increment loop Increment count loop.
:SOURce TRIGger:SOURce <source> specifies the trigger source to advance the
channel list during scanning.
