17-52 SCPI Command Reference
OUTPut subsystem
This subsystem is used to control the output of the selected source, and the interlock. These
commands are summarized in Table 17-4.
Turn source on or off
[:STATe] <b>
:OUTPut[1][:STATe] <b> Turn source on or off
Parameters <b> = 0 or OFF Turn source off (standby)
1 or ON Turn source on (operate)
Query :OUTPut? Query state of source
Description This command is used to turn the source output on or off. Measurements
cannot be made while the source is off.
Turning the source off places the SourceMeter in the idle state. The only
exception to this is when source auto clear is enabled. In this mode, the
source turns on during each source phase of the SDM cycle and then turns
off after each measurement. See :SOURce[1]:CLEar:AUTO in SOURce
subsystem.
NOTE The :SOURce:CLEar command will also turn the source off.
Interlock control
:STATe <b>
:OUTPut[1]:INTerlock:STATe <b> Control hardware interlock
Parameters <b> = 0 or OFF Disable interlock
1 or ON Enable interlock
Query :STATe? Query state of interlock
Description This command is used to enable or disable the hardware interlock. When
enabled, the source cannot be turned on unless the interlock line (pin 8 of
the rear panel Interlock - Digital I/O connector) is pulled to a logic low
state. When the interlock line goes to a logic high state, the source turns off.
See Section 12, Digital I/O port and Safety interlock for details using inter-
lock with a test fixture.
When disabled, the logic level on the interlock line has no effect on the out-
put state of the source.
