Section 6: Clarius
Make SMA cable connections to the pulse card:
1. Set up the 4200A-SCS. Refer to
2. Connect a 10.8 cm (4.25 in.) SMA cable to either end of an SMA tee.
3. Connect one of the SMA cables to TRIGGER OUT of the pulse card in the lowest numbered slot.
4. Connect the SMA tee to TRIGGER IN of the first pulse card.
5. Connect the SMA tee to TRIGGER IN of the second pulse card (which should be to the
immediate left of the card in the lowest numbered slot).
6. If your system includes four pulse cards, connect the cables and tees as described above to the
adjacent cards. There should be three SMA tees used to connect the triggering across the four
cards.
Make SMA-to-BNC connections to the pulse and SMU cards:
1. Connect an SMA-to-BNC adapter to one of the female connectors on an SMA tee.
2. Connect the tee to a triaxial-to-SMA adapter.
3. Connect a 20.3 cm (8 in.) SMA cable to the remaining SMA female connector.
4. Connect a 1.5 m (5 ft) black BNC cable to the BNC connection.
5. Repeat these steps three times.
6. Use one of these cable assemblies to connect the SMA to CHANNEL 2 of the pulse card in the
left-most slot (pulse card in the slot with the highest number).
7. Carefully insert the LEMO triaxial connector into the Force connector on the SMU in slot 4.
8. Route the BNC cable from SMU4 to the DUT terminal bulk connection. Connect a triaxial-to-BNC
adapter, if necessary.
9. Connect the cable to the probe manipulator.
10. Use another one of the cable assemblies to connect the SMA to CHANNEL 1 of the pulse card in
the left-most slot (pulse card in the slot with the highest number).
11. Carefully insert the LEMO triaxial connector into the Force connector on the SMU in slot 3.
12. Route the BNC cable from SMU3 to the DUT terminal source connection. Connect a triaxial-to-
BNC adapter, if necessary.
13. Connect the cable to the probe manipulator.
14. Use another one of the cable assemblies to connect the SMA to CHANNEL 2 of the pulse card in
the right-most slot (pulse card in the slot with the lowest number).
15. Carefully insert the LEMO triaxial connector into the Force connector on the SMU in slot 2.
16. Route the BNC cable from SMU2 to the DUT terminal drain connection. Connect a triaxial-to-BNC
adapter, if necessary.
17. Connect the cable to the probe manipulator.
18. Use the remaining cable assemby to connect the SMA to CHANNEL 1 of the pulse card in the
right-most slot (the pulse card in the slot with the lowest number).
19. Carefully insert the LEMO triaxial connector into the Force connector on the SMU in slot 1.
20. Route the BNC cable from SMU1 to the DUT terminal gate connection. Connect a triaxial-to-BNC
adapter, if necessary.
21. Connect the cable to the probe manipulator.
