Output-off states

:SMODe
:OUTPut[1]:SMODe <name>
Parameters
Query
Description
NOTE For more information on output-off states, see Section 12, "Output configuration."
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).
<name> = NORMal
ZERO
GUARd
:SMODe?
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.
