Kelvin to non-Kelvin connection
These instructions apply when the connections up to the Connector Plate are Kelvin, but
the probe is a non-Kelvin connection. Connect two Agilent 16494A triaxial cables between
the N1294A-002 banana to triaxial adapter for 4-wire and the connector plate. Connect the
triaxial connector on the probe cable as shown in Figure 3-23. Connect the FORCE and
SENSE lines on this side of the probe input terminal. A Tee Triaxial BNC adapter can be
used. For parts information, see Table 3-2.
NOTE To prevent oscillations, use triaxial cables as short as possible, if two 16494A triaxial cables with
Kelvin connections are used.
NOTE When connecting the cable and tee connector as shown in Figure 3-23, space restrictions make an
adjacent connector unusable. Since three connectors are necessary for a Kelvin connection a
connector plate must be used. Select the correct connector plate for your application.
