110 Agilent E8462A Relay Multiplexer Command Reference
TRIGger
The TRIGger command subsystem controls the triggering operation of multiplexer
modules in a switchbox.
Subsystem Syntax TRIGger
[:IMMediate]
:SLOPe <slope>
:SLOPe?
:SOURce <source>
:SOURce?
TRIGger[:IMMediate]
TRIGger[:IMMediate] Causes a trigger event to occur when the defined trigger
source is
TRIGger:SOURce BUS or TRIGger:SOURce HOLD.
Comments Executing the TRIGger[:IMMediate] Command: First, the measurement modes
must be selected using the
[ROUTe:]FUNCtion and [ROUTe:]SCAN:MODE
commands. Then
[ROUTe:]SCAN:PORT is selected, followed by the
[ROUTe:]SCAN <channel_list> command and an INITiate[:IMMediate] command.
All must be executed (unless defaults are used) before
TRIGger[:IMMediate] will
execute.
BUS or HOLD Source: If selected, the TRIGger:SOURce BUS or
TRIGger:SOURce HOLD commands remain in effect after triggering a switchbox
with the
TRIGger[:IMMediate] command.
Related Commands:
INITiate, [ROUTe:]SCAN
Example Advancing Scan Using TRIGger Command
This example uses the
TRIGger command to advance the scan of a single-module
switchbox from bank 0, channels 0 through 7. Since
TRIGger:SOURce HOLD is set,
the scan is advanced one channel each time
TRIGger is executed. For the example,
ROUTe:SCAN:MODE and ROUTe:SCAN:PORT default values of NONE are used.
TRIG:SOUR HOLD
Sets trigger source to HOLD.
SCAN (@100:107)
Scan channels 0 to 7
INIT
Begin scan, close channel 00.
loop statement
Start count loop.
TRIG
Advance scan to next channel.
increment loop
Increment loop count.
TRIGger:SLOPe
TRIGger:SLOPe <slope> Is used to select the polarity of the output trigger. For the
Agilent E8462A, this command is not used.
