To Connect Connectors to DUT
Following figure shows a connection example from the connector to DUT. Use
low-noise coaxial cable (Agilent part number: 8121-1191).
CAUTION Never connect the guard terminal to any output, including circuit common, chassis
ground, or the guard terminal of any other unit. Doing so may result in an
emergency condition.
Kelvin connections non-Kelvin connections
This connection is available only for the
Kelvin connectors. This connection can cancel
effects of cable resistance by connect sense
line and force line as close as possible to DUT
terminal.
Following connection is for the Kelvin
connectors. For the triaxial connectors or the
8 ch shielded connectors, ignore SENSE
terminal, and make connection only for
FORCE terminal. Measurement results
include residual resistance from the
connection cable.
