sourceAutorange
The state of the source autorange control. Set to one of the following:
▪ 0 or smua.AUTORANGE_OFF: Disables source autorange
▪ 1 or smua.AUTORANGE_ON: Enables source autorange
Y
SMU source function (v = voltage, i = current)
Details
This attribute indicates the source autorange state. Its value is smua.AUTORANGE_OFF when the
SMU source circuit is on a fixed range and smua.AUTORANGE_ON when it is in autorange mode.
Setting this attribute to smua.AUTORANGE_OFF puts the SMU on a fixed source range. The fixed
range used is the present SMU source circuit range.
Setting this attribute to smua.AUTORANGE_ON puts the SMU source circuit into autorange mode. If
the source output is on, the SMU immediately changes range to the range most appropriate for the
value being sourced if that range is different than the present SMU range.
Autorange is disabled if the source level is edited from the front panel. Setting the source range also
turns off autorange when set by using the smua.source.rangeY attribute.
Resetting the instrument selects the smua.AUTORANGE_ON.
Example
smua.source.autorangev = smua.AUTORANGE_ON
Enables volts source autorange.
