Output enable line
STATe <b>
:OUTPut[1]:IENABle[:STATe] <b> Control output enable
Parameters <b> = 0 or OFF Disable output enable
1 or ON Enable output enable
Query :STATe? Query state of output enable line
Description This command is used to enable or disable the output enable. When
enabled, the source cannot be turned on unless the output enable
line (pin 8 of the rear panel OUTPUT ENBLE connector) is pulled to
a logic low state. When the output enable line goes to a logic high
state, the source turns off. See
Section 13, “Digital I/O port” and
“Output enable line,” for details about using output enable with a test
fixture.
When disabled, the logic level on the outlook enable line has no
effect on the output state of the source.
TRIPped?
:OUTPut[1]:ENABle:TRIPped?
Description This query command is used to determine output enable has been
tripped. The tripped condition (“1”) means that the source can be
turned on (output enable line at logic low level).
A “0” will be returned if the source cannot be turned on (output
enable line at logic high level).
Output-off states
SMODe
:OUTPut[1]:SMODe <name> Select output-off mode
Parameters <name> = HIMPedance Disconnect Input/Output
NORMal Normal output-off state
ZERO Zero output-off state
GUARd Guard output-off state
Query :SMODe? Query output off mode
Description This command is used to select the output-off state of the SourceMe-
ter. With HIMPedance selected, the output relay opens when the
source is turned off. This disconnects external circuitry from the
SourceMeter Input/Output.
NOTE To prevent excessive wear on the output relay, do not use the HIMPedance
mode for tests that turn the output on and off frequently.
