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]
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.

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 02. 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 (@100:202)
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.
:SOURce
TRIGger:SOURce BUS | EXTernal | HOLD | IMMediate
specifies the
trigger source to advance the channel list during scanning.
