To connect
SCUU/GSWU 1
To attach the SCUU to the B1500A:
1. Attach the SCUU to the B1500A rear panel connectors for the MFCMU in the
slot N and two SMUs in the slots N-1 and N-2 (N: integer, 3 to 10).
Connection will be easy by bringing the control connectors together before
bringing the BNC connectors.
2. Fix the GSWU in the shielding box. The GSWU must be fixed to the best
position for accessing its connectors.
3. Pass the GSWU cable (Keysight N1301A-201/202) through the cable hole of the
16495K. And connect it between the SCUU and the GSWU.
4. Adjust the cable length in the shielding box, and catch in the cables by using the
cover of the 16495K.
5. Connect the proper cables from Force1/CMUH and Force2/CMUL to the 16495
connector plates or the DUT interface. See Figure 3-5.
For the Kelvin connections, also connect the proper cables from Sense1 and
Sense2 to the 16495 connector plates or the DUT interface.
6. Connect the wires (furnished, 2 ea.) to the GSWU.
7. Connect one of the wires to the Guard terminal extended from CMUH of SCUU.
Then the wire should contact the Guard terminal as close to the device as
possible.
8. Connect another one to the Guard terminal extended from CMUL of SCUU.
Then the wire should contact the Guard terminal as close to the device as
possible.
NOTE
About SCUU output cables
To perform capacitance measurements accurately, the cable length between DUT
and the SCUU output must be as short as possible.
To connect
SCUU/GSWU 2
1. Attach an end of the SCUU cable (Keysight N1301A-102) to the SCUU.
Connection will be easy by putting the SCUU and the cable connection box on
the flat table, and bringing the control connectors together before bringing the
BNC connectors.
If the SCUU is fixed inside the shielding box, pass the SCUU cable through the
cable hole of the 16495K.
