Table 2-4 GNDU Output Connections
CAUTION GNDU can sink up to 4A for the Agilent E5270B or 1.6 A for the Agilent 41501B. Use the
Agilent 16493L GNDU cable to connect the GNDU to your connector plate or test fixture.
The maximum current rating of the triaxial cable is 1 A, so do not use the triaxial cable for
the GNDU connection.
Kelvin connections non-Kelvin connections
Use a low-noise coaxial cable (Agilent 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
(Agilent 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.
