settleOption
Set to the source settling mode. Set to one of the following values:
0
or
smu
X
.SETTLE_SMOOTH
: Turns off additional settling operations (default)
1
or
smu
X
.SETTLE_FAST_RANGE
: Instructs the source-measure unit (SMU)
to use a faster procedure when changing ranges
2
or
smu
X
.SETTLE_FAST_POLARITY
: Instructs the SMU to change polarity
without going to zero
3
or
smu
X
.SETTLE_DIRECT_IRANGE
: Instructs the SMU to change the
current range directly
128
or
smu
X
.SETTLE_FAST_ALL
: Enables all

X
.SETTLE_FAST_*
operations
X
SMU channel (for example,
smua.source.settling
applies to SMU channel A)
Details
Using
smu
X
.SETTLE_FAST_RANGE
may cause the SMU to exceed the range change overshoot
specification.
smu
X
.SETTLE_FAST_POLARITY
does not go to zero when changing polarity and may create
inconsistencies at the zero crossing.
smu
X
.SETTLE_DIRECT_IRANGE
switches the SMU directly to the target range instead of the default
“range-by-range” method. This option is mutually exclusive of any other
smu
X
.SETTLE_FAST_*
commands.
Example
smua.source.settling = smua.SETTLE_FAST_POLARITY
Selects fast polarity changing for SMU channel A.
