3-52 Keysight B1505A User’s Guide, Edition 12
Accessories
• Blank Silicon Plate
This is an insulation board used for placing a DUT. To use this board, see the
following simple instruction.
1. Prepare a DUT and cable or wire, adequate length and quantity, for making
connections. The following accessories are available.
• N1254A-520 UHV/SHV to no connector cables for UHV High/Low
• N1254A-522 banana-banana wire (yellow) or N1254A-523 banana to no
connector wire (yellow) for Selector Output High/Low Force
• N1254A-508 or 509 connection wire for Selector Output High/Low
Sense, Gate, SMU, and chassis
• N1254A-512 SHV cable and N1254A-513 adapter for capacitance
measurement (Bias Tee terminals)
• N1254A-510 dolphin clip adapter or N1254A-511 cable lug adapter
2. Attach the blank silicon plate to the test fixture.
3. Connect cable/wire between the DUT and the fixture output terminals.
For making the Kelvin connection, Force and Sense must be connected to
Force and Sense of the socket module respectively.
Selector Output and Gate should be connected as follows.
• Selector Output High to DUT high (ex. Collector/Drain)
• Selector Output Low to DUT low (ex. Emitter/Source)
• Gate High to DUT drive (ex. Base/Gate Force)
• Gate Low to DUT low (ex. Emitter/Source Force)
HC/MC/DHCSMU via SMU 3 terminals should be connected as follows.
• SMU 3 High Force and Sense to DUT high
• SMU 3 Low Force and Sense to DUT low
• GNDU Force and Sense to DUT low
The GNDU signals will appear at the Selector Output Low terminals as
shown in Table 3-5.
4. Make sure the DUT location. The DUT must be placed on the blank silicon
plate properly.
