Smux.source.settling; Smux.source.sink - Keithley 2601B Reference Manual

Series 2600B System SourceMeter® Instrument Reference Manual

smuX.source.settling

This attribute contains the source settling mode.
Type TSP-Link accessible
Attribute (RW) Yes
Usage
settleOption = smuX.source.settling
smuX.source.settling = settleOption
settleOption
X
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 Model 2601B/2602B/2604B and Model
2611B/2612B/2614B. In Model 2634B/2635B/2636B, it is always enabled.
Example
smua.source.settling = smua.SETTLE_FAST_POLARITY

Affected by
SMU reset
Instrument reset
Recall setup
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
