Usage
settleOption = smuX.source.settling
smuX.source.settling = settleOption
Set to the source settling mode. Set to one of the following values:
0 or smuX.SETTLE_SMOOTH: Turns off additional settling operations (default)
1 or smuX.SETTLE_FAST_RANGE: Instructs the source-measure unit (SMU) to use
a faster procedure when changing ranges
2 or smuX.SETTLE_FAST_POLARITY: Instructs the SMU to change polarity without
going to zero
3 or smuX.SETTLE_DIRECT_IRANGE: Instructs the SMU to change the current
range directly
4 or smuX.SETTLE_SMOOTH_100NA: Enables the use of range rampers for the 100
nA range
128 or smuX.SETTLE_FAST_ALL: Enables all smuX.SETTLE_FAST_* operations
SMU channel (for example, smua.source.settling applies to SMU channel A)
Details
Using smuX.SETTLE_FAST_RANGE may cause the SMU to exceed the range change overshoot
specification.
smuX.SETTLE_FAST_POLARITY does not go to zero when changing polarity and may create
inconsistencies at the zero crossing.
smuX.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 smuX.SETTLE_FAST_*
commands.
smuX.SETTLE_SMOOTH_100NA is disabled by default in the 2601B, 2602B, 2604B, 2611B, 2612B,
and 2614B. In the 2634B, 2635B, and 2636B, it is always enabled.
Example
smua.source.settling = smua.SETTLE_FAST_POLARITY
Selects fast polarity changing for
SMU channel A.
