[PROCEDURE]
Step 1. Insert the power BJT (example: MJL4281AG) into the socket on the N1259A.
Make sure the device pin name matches to the socket numbers shown in
figure 3-11.
Step 2. Connect the Force of the HVSMU1 to the terminal 2 Force (Collector) on the
Inline Package Socket.
Step 3. Connect the GNDU1 Force to the terminal 3 Force (Emitter) on the Inline
Package Socket.
Step 4. Connect the GNDU1 Sense to the terminal 3 Sense (Emitter) on the Inline
Package Socket.
