Ground unit and preamplifier remote sense connections
The next figure shows a typical remote sense connection scheme using two preamplifiers, two DUTs,
and the ground unit. Make connections as follows:
•
Connect the preamplifier FORCE and SENSE signals to the two DUT HI terminals.
•
Connect both DUT LO terminals together, and connect the GNDU SENSE and FORCE signals to
the common DUT LO connection point.
Using the ground unit with more than two SMUs
The ground unit should also be used for circuit COMMON connections when using more than two
SMUs. Make your connections using the same basic connection scheme shown in the previous
ground unit figures. Be sure to connect all your DUT LO terminals to the GNDU FORCE terminal (and
SENSE terminal when using remote sensing).
