Figure 3-18 SCUU Output Kelvin Connection (Remote Sensing)
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 will work as same as
Table 3-8.
When the MFCMU is used, the sense lines can be ignored. And a Kelvin path is
used for the CMU high, and the other one is used for the CMU low. 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.
