About SMU

Source/monitor unit (SMU) can apply DC voltage or current, and can measure DC
current or voltage. Figure 2-2 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
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, see Agilent EasyEXPERT User's
Guide.
