Remarks
• Use the
smuX.source.limiti
attribute to limit the current output of the voltage
source. Use
smuX.source.limitv
to limit the voltage output of the current source.
The SMU will always choose (auto range) the source range for the limit setting.
• This attribute should be set in the test sequence before the turning the source on.
• Reading this attribute indicates the presently set compliance value. Use
smuX.source.compliance
to read the state of source compliance.
Details
(basic operation).

Example
Sets V-compliance to 30V for SMU A:
smua.source.limitv = 30
smuX.source.lowrangeY
X = SMU channel (a or b)
Y = SMU measure function (v or i) where v = voltage, i = current
Attribute
Lowest source range that will be used during autoranging.
Usage
rangeval = smuX.source.lowrangeY
-- Reads low range.
smuX.source.lowrangeY = rangeval
-- Writes low range.
rangeval
Set to the lowest voltage or current to be sourced.
Remarks
• This attribute is used with source autoranging to put a lower bound on the range
used. Lower ranges generally require greater settling times. By setting a low range
value, sourcing small values might be able to be made with less settling time.
• If the instrument is set to auto range and it is on a range lower than the one specified
by
rangeval
, the source range will be changed to the range specified by
rangeval
.

Example
Sets volts lowrange for Model 2601/2602 SMU A to 1V. This prevents the source from
using the 100mV range when sourcing voltage:
smua.source.lowrangev = 1
