smua.source.limitY
This attribute sets compliance limits.
SMU reset
Instrument reset
Recall setup
Limit voltage: 40 (40 V)
Limit current: 1 (1 A)
Limit power: 0 (disabled)
Usage
limit = smua.source.limitY
smua.source.limitY = limit
The compliance limit value; set to one of the following values:
â–ª Voltage compliance: 10 mV to 40 V
â–ª Current compliance: 10 nA to 3 A
â–ª Power compliance (in watts)
SMU function (v = voltage, i = current, p = power)
Details
Use the smua.source.limiti attribute to limit the current output of the voltage source. Use
smua.source.limitv to limit the voltage output of the current source. The SMU always uses
autoranging for the limit setting. Use the smua.source.limitp attribute to limit the output power of
the source.
This attribute should be set in the test sequence before the turning the source on.
Using a limit value of 0 results in error code 1102, "Parameter too small," for v and i. Setting this
attribute to zero disables power compliance for p. When setting the power compliance limit to a
nonzero value, the SMU adjusts the source limit where appropriate to limit the output to the specified
power. The SMU uses the lower of the programmed compliance value (the compliance level that
would be used if power compliance were disabled) or the limit calculated from the power
compliance setting.
Reading this attribute indicates the presently set compliance value. Use
smua.source.compliance to read the state of source compliance.
Example
Sets the voltage limit to 15 V.
