sourceRangeLow
Set to the lowest voltage (in volts) or current (in amperes) range to be used

smua.source.lowrangev
applies to SMU channel A)
Y
SMU source function (v = voltage, i = current)
Details
This attribute is used with source autoranging to put a lower bound on the range that is used. Lower
ranges generally require greater settling times. If you set a low-range value, you might be able to
source small values with less settling time.
If the instrument is set to autorange and it is on a range lower than the one specified by
sourceRangeLow
, the source range will be changed to the range specified by
sourceRangeLow
.
Example
smua.source.lowrangev = 1
Sets volts low range for Models
2601B/2602B/2604B SMU A to 1
V. This prevents the source from
using the 100 mV range when
sourcing voltage.
