The SCUU should be connected to the DUT by using coaxial cables and wires as
shown above. Also the SCUU should be connected to the GSWU inside the
shielding box by using a control cable through the 16495K plate.
When a SMU is used for the measurements, the Kelvin paths/force lines will work
as same as Table 3-8. Then the sense line is not extended to the DUT.
When the MFCMU is used, the sense lines can be ignored. And a force line is used
for the CMU high signal, and the other one is used for the CMU low signal. For the
accurate impedance measurements, wires must be connected to the GSWU from the
CMH guard and the CML guard as near as possible to the DUT.
