Introduction
Measurement Modules
Measurement Modules
The source/monitor unit (SMU) can force a constant voltage or current, and can
measure a DC current or voltage.
Figure 2-1 is a simplified SMU circuit diagram. The SMU can perform the
following operations:
• Apply voltage and measures current
• Apply current and measures voltage
• Apply voltage and measures voltage
• Apply current and measures current
NOTE To select the SMU operation mode in the GPIB remote condition, enter the CMM
command.

Compliance
The SMU has a compliance feature that limits output voltage or current to prevent
damage to the device under test. When the SMU applies voltage, you can specify
current compliance. When the SMU applies current, you can specify voltage
compliance. For details about the compliance, refer to “Compliance” on page 6-9.
