smuX.source.output
This attribute sets the source output state (on or off).
Type TSP-Link accessible
Attribute (RW) Yes
Usage
sourceOutput = smuX.source.output
smuX.source.output = sourceOutput
sourceOutput
X
Details
Reading this attribute returns the output state of the source. Setting this attribute switches the output of the
source on or off.
When the output is switched on, the SMU sources either voltage or current, as set by smuX.source.func.
Setting this attribute to smuX.OUTPUT_HIGH_Z causes the output to turn off and go to the High Z mode. If the
smuX.source.output is read after setting this attribute to smuX.OUTPUT_HIGH_Z, it returns 0.
Example
smua.source.output = smua.OUTPUT_ON

The source's output state setting; set to one of the following values:
0 or smuX.OUTPUT_OFF: Turns off the source output
1 or smuX.OUTPUT_ON: Turns on the source output
2 or smuX.OUTPUT_HIGH_Z: Turns off the output in high Z mode (allows you to go
to high Z mode without first setting the smuX.source.offmode attribute to
smuX.OUTPUT_HIGH_Z)
