Example
smua.source.outputenableaction = smua.OE_OUTPUT_OFF
Sets SMU channel A to turn off the output if the output enable line goes low (deasserted).

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 6 V range causes an
overrange condition.
Example
smua.source.rangev = 1
