For 2601B, 2602B, or 2604B, this attribute controls the action the SMU takes when the output enable
line is deasserted.
When set to smuX.OE_NONE, the SMU takes no action when the output enable line goes low
(deasserted).
When set to smuX.OE_OUTPUT_OFF and the output enable line is de-asserted, the SMU turns its
output off as if the smuX.source.output = smuX.OUTPUT_OFF command had been received.
The SMU does not automatically turn its output on when the output enable line returns to the
high state.
If the output enable line is not asserted when this attribute is set to smuX.OE_OUTPUT_OFF and the
output is on, the output turns off immediately.
Detection of the output enable line going low does not abort any running scripts. This may cause
execution errors.
For models that have a safety interlock (2611B, 2612B, 2614B, 2635B, 2636B, and 2634B), this
attribute dictates the source output behavior when the interlock line is not engaged and the source is
configured for safe operation.
In the following situations, source output automatically turns off when the interlock is disengaged and
the output cannot be turned on unless the interlock is engaged:
• When sourcing voltage on the 20 V range or lower.
• When sourcing current with a limit of 20 V or less and the
smuX.source.outputenableaction attribute is set to smuX.OE_OUTPUT_OFF.
In the following situations, the source ignores the state of the interlock signal and the output can be
turned on regardless of the interlock state:
• When sourcing voltage on the 20 V range or lower.
• When sourcing current with a limit of 20 V or less and the
smuX.source.outputenableaction attribute is set to smuX.OE_NONE.
In the following situations, the source output automatically turns off when the interlock is disengaged,
the output cannot be turned on unless the interlock is engaged, and the
smuX.source.outputenableaction attribute is ignored:
• When sourcing voltage on the 200 V range.
• When sourcing current with a limit greater than 20 V.
