offfunc
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:
0
or
smu
X
.OUTPUT_DCAMPS
: Source 0 A
1
or
smu
X
.OUTPUT_DCVOLTS
: Source 0 V
X
SMU channel (for example,
smua.source.offfunc
applies to SMU channel A)
Details
This attribute controls the source function used when the output is turned off and the
smu
X
.source.offmode
is
set to
smu
X
.OUTPUT_NORMAL
. Set this attribute to
smu
X
.OUTPUT_DCVOLTS
for the source to be a 0 V source
when the output is off (
smu
X
.source.offlimiti
is used). Set it to
smu
X
.OUTPUT_DCAMPS
for the source to
be a 0 A source when the output is off (
smu
X
.source.offlimitv
is used).
This attribute is only used when the
smu
X
.source.offmode
attribute is set to
smu
X
.OUTPUT_NORMAL
.
Example
smua.source.offfunc = smua.OUTPUT_DCVOLTS
Sets the normal output-off mode to
source 0 V when the output is
turned off for SMU channel A.
