SCPI Command Reference 17-53
:TRIPped?
:OUTPut[1]:INTerlock:TRIPped?
Description
This query command is used to determine if the enabled interlock has been
tripped. The tripped condition (
“ 1 ” ) means that the source can be turned on
(interlock line at logic low level).
A
“ 0 ” will be returned if the source cannot be turned on (interlock line at
logic high level).
Output-off states
:SMODe
:OUTPut[1]:SMODe <name> Select output-off mode
Parameters
<name> = 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 SourceMeter.
With NORMal selected (which is the default), the V-Source is selected and
set to 0V when the output is turned off. Compliance is set to 0.5% full scale
of the present current range.
In the ZERO output-off state when the V-Source OUTPUT is turned off, the
V-Source is set to 0V and current compliance is not changed. When the
I-Source OUTPUT is turned off, the V-Source mode is selected and set to
0V. Current compliance is set to the programmed Source I value or to 0.5%
full scale of the present current range, whichever is greater.
The ZERO output-off state is typically used with the V-Source and Output
Auto-On (see the :SOURce1:CLEar:AUTO command) to generate voltage
waveforms that alternate between 0V and the programmed output-on
voltage.
With GUARd selected, the I-Source is selected and set to 0A. Voltage com-
pliance is set to 0.5% full scale of the present voltage range. This output-off
state should be used when performing 6-wire guarded ohms measurements
or for any other load that uses an active source.
NOTE For more information on output-off states, see Section 12, “Output configuration.”
