Connection Guide for Wafer Prober
SMU/GNDU connection with prober
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 an Keysight 16493K Kelvin triaxial cable
(or two Keysight 16494A triaxial cables) between the SMU and the Connector plate.
Connect the triaxial connector on the probe cable as shown in Figure 3-7. 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 3-6.
NOTE To prevent oscillations, do not use longer than 1.5m, if user uses two 16494A triaxial
cables with Kelvin connections.
NOTE When connecting the cable and tee connector as shown in Figure 3-7, 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. To make two Kelvin connections, use an Keysight 16495H. To make three
Kelvin connections, use an Keysight 16495J.
