Details
For the Models 2601B/2602B/2604B, this attribute controls the SMU action taken when the output
enable line is deasserted.
When set to
smu
X
.OE_NONE
, the SMU will take no action when the output enable line goes low
(deasserted).
When set to
smu
X
.OE_OUTPUT_OFF
and the output enable line is de-asserted, the SMU will turn its
output off as if the
smu
X
.source.output = smu
X
.OUTPUT_OFF
command had been received.
The SMU will 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
smu
X
.OE_OUTPUT_OFF
and the
output is on, the output will turn off immediately.
Detection of the output enable line going low will not abort any running scripts. This may cause
execution errors.
For models that have a safety interlock (Models 2611B/ 2612B/2614B/2635B/2636B/2634B), this
attribute dictates the source output behavior when the interlock line is not engaged and the source is
configured for safe operation.
When sourcing voltage on the 20 V range or lower, or sourcing current with a limit of 20 V or less and
the
smuX.source.outputenableaction
attribute is set to
smuX.OE_OUTPUT_OFF
, the source
output will automatically turn off when the interlock is disengaged. Furthermore, the output cannot be
turned on unless the interlock is engaged.
When sourcing voltage on the 20 V range or lower, or sourcing current with a limit of 20 V or less and
the smuX.source.outputenableaction attribute is set to smuX.OE_NONE, the source will ignore the
state of the interlock signal. The output can be turned on regardless of the interlock state.
When sourcing voltage on the 200 V range, or sourcing current with a limit greater than 20 V, the
source output will automatically turn off when the interlock is disengaged. Furthermore, the output
cannot be turned on unless the interlock is engaged. The
smuX.source.outputenableaction
attribute will be ignored in this case.
Example
smua.source.outputenableaction = smua.OE_OUTPUT_OFF
Sets SMU channel A to turn off the
output if the output enable line
goes low (deasserted).
