Details
This attribute contains a value that sets the source-measure unit (SMU) to a fixed range large enough to source
the value. When read, the attribute contains the range the instrument is presently on when in autorange.
Assigning a value to this attribute sets the SMU to a fixed range large enough to source the assigned value. The
instrument selects the best range for sourcing a value of rangeValue.
Reading this attribute returns the positive full-scale value of the source range the SMU is currently using. With
source autoranging enabled, the output level controls the range. Querying the range after the level is set returns
the range the instrument chose as appropriate for that source level.
This attribute is primarily intended to eliminate the time required by the automatic range selection performed by a
sourcing instrument. Because selecting a fixed range prevents autoranging, an overrange condition can occur.
For example, sourcing 10.0 V on the Model 2601B/2602B/2604B 6 V range or sourcing 5.0 V on the Model
2611B/2612B/2614B 2 V range causes an overrange condition.
Example
smua.source.rangev = 1
