accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage
limit = smuX.source.limitv
-- Reads voltage compliance limit.
smuX.source.limitv = limit
-- Writes voltage compliance limit.
limit = smuX.source.limiti
-- Reads current compliance limit.
smuX.source.limiti = limit
-- Writes current compliance limit.
limit
2601A/2602A voltage compliance from 10 mV to ±40 (volts).
2601A/2602A/2611A/2612A current compliance from
10 nA to ±3 A.
2611A/2612A/2635A/2636A voltage compliance from
20 mV to ±200 (volts).
2635A/2636A current compliance from 100 pA to ±1.5 A.
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.
• Using a
limit
value of
0
will result in a parameter too small error.
• Reading this attribute indicates the presently set compliance value. Use
smuX.source.compliance
to read the state of source compliance.

Example
Sets V-compliance to 30V for SMU A:
smua.source.limitv = 30
