Preamplifier connections
When using more than one preamplifier, use the ground unit for circuit COMMON connections
instead of the outer shield of the preamplifier terminals (refer to
(on page 2-8)).
Connecting the preamplifier to the SMU
The preamplifier must be connected to the SMU before use. The connection method used depends
on the mounting method (rear panel or remote). See
(on page 3-16) for details.
Turn off the system and disconnect the power cord before connecting or disconnecting the
preamplifier. Failure to do so may result in SMU or preamplifier damage, possibly voiding the
warranty.
Preamplifier local sense connections
The next figures show typical preamplifier connections using local sensing. Use a triaxial cable to
make your connections as follows:
•
Connect preamplifier FORCE (center conductor of FORCE terminal) to DUT HI.
•
Connect signal COMMON (outer shield of FORCE terminal) to DUT LO.
