Device connections
Using the supplied cables, connect the output terminals of the instruments directly to the MOSFET
terminals in the shielded test fixture. The triaxial terminals on the shielded test fixture allow you to
connect to the device and maintain a completely shielded and guarded test setup.
Hazardous voltages may be present on all output and guard terminals. To prevent electrical
shock that could cause injury or death, never connect or disconnect from the 4200A-SCS
while the output is on.
To prevent electric shock, test connections must be configured such that the user cannot
come in contact with test leads, conductors, or any device under test (DUT) that is in contact
with the conductors. It is good practice to disconnect DUTs from the instrument before
powering up the instrument. Safe installation requires proper shields, barriers, and grounding
to prevent contact with test lead and conductors.
Connection schematic
The hardware connections from the output of the instruments in the 4200A-SCS chassis to the test
fixture that contains the MOSFET are shown in the following figure. All of the connections are 2-wire
and only the Force terminal of each SMU is used. The SMUs and GNDU are each connected to a
different terminal of the 3-terminal MOSFET.
