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 the current and voltage functions.
Example
smu.source.func = smu.FUNC_DC_CURRENT
smu.source.autorange = smu.ON
Set the source function to current.
Set the instrument to select the
source range automatically.
