Ground unit and preamplifier local sense connections
The next figure shows a typical local sense connection scheme using two preamplifiers, two DUTs,
and the ground unit. Make connections as follows:
• Connect the two preamplifier FORCE signals to the two DUT HI terminals.
• Connect both DUT LO terminals together, and connect the GNDU FORCE signal to the common
DUT LO connection point.
