Usage
outputAction = smuX.source.outputenableaction
smuX.source.outputenableaction = outputAction
outputAction
The output enable action of the source; set to one of the following values:
0 or smuX.OE_NONE: No action
1 or smu
X
.OE_OUTPUT_OFF: Turns the source output off
X
Source-measure unit (SMU) channel (for example,
smua.source.outputenableaction applies to SMU channel A)
Details
For the Models 2601B/2602B/2604B, this attribute controls the SMU action taken when the output enable line is
deasserted.
When set to smuX.OE_NONE, the SMU will take 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 will turn its output off as
if the smuX.source.output = smuX.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 smuX.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).
