SMU connections

The following topics explain how to connect the source-measure units (SMUs) to the device under
test (DUT).
Do not touch test cables or connectors when powering up the 4200A-SCS. Hazardous
voltage may be output momentarily, posing a safety hazard that could result in personal
injury or death.
Do not turn on the 4200A-SCS until you have reviewed the safe power-up procedure in
Powering the 4200A-SCS (on page 2-16).
Do not connect the DUT to the 4200A-SCS before powering it up, because the hazardous voltage
that may be output momentarily at power-up could damage the DUT.
If your 4200A-SCS includes preamplifiers, all tests should be performed using the preamplifiers, as
the installed SMUs were optimized at the factory to use them.
