To Connect SCUU/GSWU
Keysight N1301A-100 SMU CMU Unify Unit (SCUU) is used to switch the
measurement resource (CMU or SMU) to be connected to the DUT.
Keysight N1301A-200 Guard Switch Unit (GSWU) is used to connect the CMU
high and low guard lines together near the DUT. The connection is broken when the
SCUU is in the SMU connection state. The GSWU is effective for the accurate
impedance measurement.
NOTE For the installation of the SCUU/GSWU and the connection to the DUT interface
(probe card, manipulators, and so on), contact your favorite prober vender. The
prober vender will have the solutions. Dimensions of the SCUU are 148 mm (W)
75 mm (H) 70 mm (D). Dimensions of the GSWU are 33.2 mm (W) 41.5 mm
(H) 32.8 mm (D).
