For all class exercises, you need the 28-pin dual in line socket which comes standard with the 4145
fixture (16058A) or the newer fixture (16442A/B). Either fixture works fine.
With the 16442A/B fixture, note that there are two SMU numbering schemes....3 SMUs with force
and sense, or six SMUs with force only. For this class example we will use the six (6) SMU scheme.
Connect the cables between the B1500A and test fixture as follows.
SMU1 : SMU1
SMU2 : SMU2
SMU3 : SMU3
SMU4 : SMU4
Connect jumper leads as follows.
Terminal 15 : SMU4 F terminal
Terminal 16 : SMU3 F terminal
Terminal 17 : SMU2 F terminal
Locate the bipolar transistor in the corner of the socket as shown, with the flat side of the device
facing toward you.
Unlike the MOS device, the bipolar transistor is not static sensitive. You may touch the leads
without using a ground strap.
