3.4.2 ASU connection
Each ASU has one D-sub control cable, one triaxial cable, and (optionally) two coaxial
cables connected to it. The cables can be connected to the ASU inside the shielding box
through the 16495K plate. The ASU outputs should be connected to the DUT by using
triaxial cables as shown in Figure 3-18. When making IV measurements with the SMUs,
all measurements are Kelvin. The SENSE line information is fed back to the SMU via the
D-sub cable. When making CV measurements, the four-terminal pair (4TP) connections
are correctly terminated inside of the ASUs. The ASUs also allow for a current return path
between the outer conductors to stabilize the series inductance and improve accuracy. You
must connect the furnished wire between the two ASUs to enable this feature.
