Keithley 2651A Reference Manual

Section 7: Command reference Model 2651A High Power System SourceMeter® Instrument Reference Manual
7-222 2651A-901-01 Rev. A / March 2011
Details
Reading this attribute gives the output state of the source. Setting this attribute will turn the output of the source
on or off. The default for the source is off. When the output is turned on, the SMU will source either voltage or
current as dictated by the smuX.source.func setting.
Setting this attribute equal to smuX.OUTPUT_HIGH_Z will cause the output to turn off and go to the High Z mode.
If the smuX.source.output is then read it will return 0.
Example
smua.source.output = smua.OUTPUT_ON
Turns on SMU Channel A source
output on.

smuX.source.outputenableaction
This attribute controls output enable action of the source.

Usage
outputAction = smuX.source.outputenableaction
smuX.source.outputenableaction = outputAction
outputAction
The source's output enable action. Set to one of the following values:
0 or smuX.OE_NONE: No action.
1 or smuX.OE_OUTPUT_OFF: Turns the source output off.
X
SMU channel (for example, smua.source.outputenableaction applies to
SMU Channel A).
Details
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.
