Usage
autoRange = smua.measure.autorangeY
smua.measure.autorangeY = autoRange
autoRange
The state of the measurement autorange setting; set to one of the following values:
▪ 0 or smua.AUTORANGE_OFF: Disabled
▪ 1 or smua.AUTORANGE_ON: Enabled
▪ 2 or smua.AUTORANGE_FOLLOW_LIMIT: Measure range automatically set to
the limit range
Y
SMU measure function (v = voltage, i = current)
Details
This attribute indicates the measurement autorange state. Its value is smua.AUTORANGE_OFF when
the SMU measure 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 range. The fixed range is the
present SMU measure range.
Setting this attribute to smua.AUTORANGE_ON puts the SMU measure circuit in autorange mode. It
remains on its present measure range until the next measurement is requested.
If source high capacitance mode is enabled, current autorange is set to
smua.AUTORANGE_FOLLOW_LIMIT and cannot be changed.
Example
smua.measure.autorangev = smua.AUTORANGE_ON
Enables voltage measurement autoranging.
