TRIGger subsystem

The Trigger subsystem is made up of a series of commands and subsystems to configure
the Trigger Model. These commands and subsystems are summarized in
NOTE See Section
model.
Clear input triggers
CLEar
:TRIGger:CLEar
Description When this action command is sent, any pending (latched) input triggers
are cleared immediately. When the SourceMeter is being triggered by
another instrument, it may inadvertently receive and latch input triggers
that do not get executed. These pending triggers could adversely affect
subsequent operation.
When using external triggering, it is recommended that TRIGger:CLEar
be sent after sending the ABORt command and at the beginning of a
program before sending an initiate command. (See "INITiate"
command.)
Initiate source/measure cycle
INITiate
:INITiate[:IMMediate]
Description
This command is used to initiate source-measure operation by taking the
SourceMeter out of idle. The :READ? and :MEASure? commands also
perform an initiation.
Note that if auto output-off is disabled (SOURce1:CLEar:AUTO OFF),
the source output must first be turned on before an initiation can be per-
formed. The :MEASure? command automatically turns the output
source on before performing the initiation.
