Basic connections
The simplest method to connect SMUs to the device under test (DUT) is to use one SMU for each
terminal of the device. When setting up a test, the FORCE terminal (center conductor) of the SMU is
used to apply voltage or current to the device. The FORCE terminal or ground unit can also be used
to connect the device terminal to the COMMON circuit.
Complete details on connections (including SENSE terminal connections) are provided in the
"Connections and configuration" section of the
Model 4200A-SCS Reference Manual
.
The next figure shows SMU connections to 2-terminal, 3-terminal, and 4-terminal devices. Notice that
only the FORCE HI terminal of each SMU is connected to the device terminal. FORCE HI is the
center conductor of the triaxial cable.
Connecting the SMU or ground unit SENSE terminal without the FORCE terminal may damage
the instrument and return erroneous results.
