SCUU/GSWU
SCUU: SMU CMU Unify Unit
GSWU: Guard Switch Unit
The SCUU multiplexes the outputs from two SMUs (MPSMUs and/or HRSMUs)
and the CMU. The SCUU outputs are two sets of Kelvin triaxial ports (Force and
Sense). The SCUU also allows the SMUs to act as DC bias sources in conjunction
with the CMU. Special cables are available to connect the SMUs and CMU with the
SCUU, and an auto-detect feature automatically compensates for the cable length
going to the SCUU.
The GSWU contains a relay that automatically opens for IV measurements and
closes for CV measurements, forming a guard return path to improve CV
measurement accuracy.
