Series 2600A System SourceMeter® Instruments Reference Manual Section 3: Basic Operation
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.
Basic circuit configurations
The fundamental source-measure configurations for the Series 2600A are shown in Figure 3-1.
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
Section 4 for more detailed information on these circuit configurations.

Operation considerations
The following paragraphs discuss the warm-up period and auto zero.
Warm-up
The Series 2600A must be turned on and allowed to warm up for at least two hours to achieve
rated accuracies.

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 2601A/2611A/2635A; smuX = smua (Channel A) or smub (Channel B) for the
Model 2602A/2612A/2636A.
