Details
This command indicates the state of the range for the selected source. When automatic source range is
disabled, the source range is set manually.
When automatic source range is enabled, the instrument selects the range that is most appropriate for the value
that is being sourced. The output level controls the range. If you read the range after the output level is set, the
instrument returns the range that the instrument chose as appropriate for that source level.
If the source range is set to a specific value from the front panel or a remote command, the setting for automatic
range is set to disabled.
Only available for current and voltage functions.
Example
smu.source.func = smu.FUNC_DC_CURRENT
