Limit commands
Command*
Description
smu
X
.source.limiti = limit
Set current limit.
smu
X
.source.limitv = limit
Set voltage limit.
smu
X
.source.limitp = limit
Set power limit.
compliance = smu
X
.source.compliance
Test if in limit (
true
= in limit;
false
= not in limit).

smu
X
can be
smua
for channel A or
smub
for channel B
To set the limit, send the command with the limit value as the parameter. The following programming
example illustrates how to set the current, voltage, and power limit to 50 mA, 4 V, and 1 W,
respectively:
smua.source.limiti = 50e-3
smua.source.limitv = 4
smua.source.limitp = 1
