To Connect the GNDU Output
The following figures show connection examples for the GNDU output.
CAUTION Use Keysight 16493L GNDU cable to connect the GNDU to your connector plate or
test fixture. Do not use the triaxial cable. The GNDU is rated for up to 4 A
(E5260A/E5270B) or 2.2 A (E5262A/E5263A), while the maximum current rating
of the triaxial cable is 1 A.
Kelvin connections non-Kelvin connections
Use a low-noise coaxial cable (Keysight part
number 8121-1189) from the connector to the
prober, socket, or DUT as shown.
To cancel the effects of cable resistance, connect
the Sense line and Force line as close as possible to
the terminal of the DUT.
Short the Sense and Force on the connector as
shown below. Measurement data will include the
residual resistance of the connection wire.
Use AWG 22 single-strand insulated wire
(Keysight part number 8150-2639) from the
connector plate to the prober, socket, or DUT.
For a quick connection where measurement
accuracy is not critical, connect only Force to the
DUT, without shorting the Sense and Force. With
this connection, the measurement data will include
residual resistance from the connection cable
between the GNDU and the connector plate.
