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.
