Usage
sourceLimit
= smu
X
.source.offlimit
Y
smu
X
.source.offlimit
Y
=
sourceLimit
sourceLimit
Set to the limit to be used when the SMU is in normal output-off mode
X
Source-measure unit (SMU) channel (for example,
smua.source.offlimiti
applies to SMU channel A)
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
smu
X
.contact.check()
and
smu
X
.contact.r()
for details.
Example
smua.source.offlimiti = 10e-3
Changes the normal output-off
mode limit to 10 mA for SMU
channel A.
