Tektronix Keithley 2601B-PULSE Reference Manual

Section 11: TSP command reference Model 2601B-PULSE System SourceMeter Instrument Reference Manual
11-232 2601B-PULSE-901-01A April 2020
Details
This attribute controls the source function used when the output is turned off and
smua.source.offmode is set to smua.OUTPUT_NORMAL.
Set this attribute to smua.OUTPUT_DCVOLTS for the source to be a 0 V source when the output is off
(smua.source.offlimiti is used).
Set it to smua.OUTPUT_DCAMPS for the source to be a 0 A source when the output is off
(smua.source.offlimitv is used).
If the pulser is enabled and the output-off mode is set to normal, the smua.source.offfunc
setting is ignored and the output circuit is shorted.
Example
smua.source.offmode = smua.OUTPUT_NORMAL
smua.source.offfunc = smua.OUTPUT_DCVOLTS
Sets the normal output-off mode to source 0 V when the output is turned off.

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

Usage
sourceLimit = smua.source.offlimitY
smua.source.offlimitY = sourceLimit
sourceLimit
Set to the limit to be used when the SMU is in normal output-off mode
Y
SMU source function (v = voltage, i = current)
Details
Setting the current limit to lower than 1 mA may interfere with operation of the contact check function.
See smua.contact.check() and smua.contact.r() for details.
Example
smua.source.offlimiti = 10e-3
Changes the normal output-off mode limit to 10 mA.
