Kelvin connections
Use low-noise coaxial cable (Agilent part number
8121-1191) from the connector to the prober,
socket, or DUT as shown.
See Figure 3-13 and Figure 3-15 for the ASU and
SCUU connections respectively.
To cancel the effects of cable resistance, connect
the Sense line and Force line as close as possible to
the DUT terminal.
To prevent oscillations, do not use cables longer
than 1.5 m.

To Minimize Leakage Current
For the highly accurate current forcing and measurements, surround all force and
sense lines by a guard as far as possible, and physically stable the cables with tape.

non-Kelvin connections
Use low-noise coaxial cable (Agilent part number
8121-1191). The following figure is for the
connection using Kelvin triaxial cable.
For the connection using triaxial cable, connect
the cable to the Force terminal only.
In this connection, measurement data will include
residual resistance from the connection cable.
See Figure 3-14 and Figure 3-16 for the ASU and
SCUU connections respectively.
