Section 4: Basic Operation
Remote compliance limit
summarizes basic commands to program the compliance limit. See
for more
details on these commands. To program the compliance, simply send the command using the
desired parameter. For example, the following commands set the current and voltage compliance
to 50mA and 4V:
smua.source.limiti = 50e-3
smua.source.limitv = 4
The following command will print the compliance state:
print (smua.source.compliance)
A returned value of 1 indicates that the voltage limit has been reached if the unit is configured as a
current source, or that the current limit has been reached if the unit is configured as a voltage
source.

Compliance commands
Command
*
Description
smuX.source.limiti = limit
smuX.source.limitv = limit
compliance = smuX.source.compliance
Set current compliance limit.
Set voltage compliance limit.
Test if in compliance (1 = in compliance;
0 = not in compliance).
*smuX = smua for the Model 2601/2611/2635; smuX = smua (Channel A) or smub (Channel B) for the Model 2602/2612/2636.
Basic circuit configurations
The fundamental source-measure configurations for the SourceMeter are shown in
.
When sourcing voltage, you can measure current or voltage (configuration A). When sourcing
current, you can measure voltage or current (configuration B). See
"Basic circuit configurations"
in
for more detailed information on these circuit configurations.
