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.

Direct connections to array DUT for disturb testing

Cabling instructions for direct connections to an array DUT are below. These instructions are
compatible with the following projects:
•
flashdisturb-nand
•
flashendurance-nand
In all of the following steps, apply sufficient torque using an 8 in. lb. torque wrench.
Refer to the drawing in
Make the SMA connections:
1. Set up the 4200A-SCS. Refer to "Connections and configuration" in Model 4200A-SCS Setup and
Maintenance.
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 DUT arrays:
1. Connect an SMA-to-BNC adapter to a 1.5 m (5 ft) black BNC cable.
2. Connect SMA end of the SMA-to-BNC adapter to CHANNEL 2 of the pulse card in the left-most
slot (the pulse card in the slot with the highest number).
3. Route the BNC cable to the DUT array Bit Line Select connection. If necessary, use a
triaxial-to-BNC adapter.
4. Connect the cable to the probe manipulator.
5. Insert the LEMO end of a black LEMO triaxial to 3-slot triaxial cable into the Force connection on
the left-most SMU in slot 4.
6. Route the triaxial cable from SMU4 to the DUT array BL1 connection.
7. Connect the cable to the probe manipulator.
