Smux.source.offlimity - Keithley 2651A Reference Manual

Model 2651A High Power System SourceMeter® Instrument Reference Manual
Usage
offfunc = smuX.source.offfunc
smuX.source.offfunc = offfunc

Details
This attribute controls the source function used when the output is turned off and the smuX.source.offmode is
set to smuX.OUTPUT_NORMAL. Set this attribute to smuX.OUTPUT_DCVOLTS for the source to be a 0 V source
when the output is off (smuX.source.offlimiti is used). Set it to smuX.OUTPUT_DCAMPS for the source to
be a 0 A source when the output is off (smuX.source.offlimitv is used).
This attribute is only used when the smuX.source.offmode attribute is set to smuX.OUTPUT_NORMAL.
Example
smua.source.offfunc = smua.OUTPUT_DCVOLTS

This attribute sets the limit (current or voltage) used when the source-measure unit (SMU) is in normal output-off
mode.

2651A-901-01 Rev. A / March 2011
Set to the source function to be used when the output is off and the SMU is in
normal output-off mode. Set to one of the following values:
smuX.OUTPUT_DCVOLTS: Source 0 V
smuX.OUTPUT_DCAMPS: Source 0 A
SMU channel (for example, smua.source.offfunc applies to SMU channel A)
(see "Output-off states" on page 2-59)

Recall
Set to the limit to be used when the SMU is in normal output-off mode
SMU channel (for example, smua.source.offlimiti applies to SMU channel A)
SMU source function (v = voltage, i = current).
(on page 7-186) and smuX.contact.r()
Sets the normal output-off mode to
source 0 V when the output is
turned off for SMU channel A.
