SENSE terminal
The SENSE terminal is a standard triaxial connector used to apply the ground unit SENSE signal to
the DUT in a remote sense application. The center pin is SENSE, the inner shield is GUARD, and the
outer shield is circuit COMMON. When the ground unit SENSE signal is connected to a DUT, all
SMU/preamplifier measurements will be made relative to this DUT connection.
The SENSE terminal does not need to be connected to the DUT for the SMU to operate correctly.
Remote sensing is automatic. If SENSE is connected to the DUT, errors due to voltage drops in the
FORCE path between the SMU and the DUT will be eliminated; otherwise, the SMU will sense
locally.
Preamplifier CONTROL connector
The preamplifier CONTROL connector connects to the SMU PA CNTRL connector and provides both
power and signal connections from the 4200-SMU or 4210-SMU to the 4200-PA preamplifier.
