Triaxial cables
Triaxial cables are supplied to make connections to the DUT (device under test). With preamplifiers
installed, use the low-noise triaxial cables, which are terminated with 3-slot triaxial connectors on both
ends. One end of the cable connects to the preamplifier and the other end connects to the DUT test
fixture or probe station.
Figure 8: Triaxial cable 4200-TRX-X
If your system does not have preamplifiers installed, use the cables that have a miniature triaxial
connector on one end and a standard 3-slot triaxial connector on the other end. The cable end that is
terminated with the miniature connector connects directly to the SMU, and the other end connects to
the test fixture or probe station.
Figure 9: Triaxial cable 4200-MTRX-X
With preamplifiers installed, NEVER make connections directly to any of the miniature triaxial
connectors on the SMU modules. This may result in damage to the SMU or DUT or may
produce corrupt data.
