DUT test connections
Hazardous voltages may be present on all output and guard terminals. To prevent electrical shock
that could cause injury or death, never make or break connections to the Model 2657A while the
instrument is powered on. Turn off the equipment from the front panel or disconnect the main
power cord from the rear of the Model 2657A before handling cables. Putting the equipment into
standby does not guarantee that the outputs are powered off if a hardware or software fault occurs.
When connecting to the Model 2657A SMU outputs, make sure to use devices and cables that have
ratings for the sourced voltages. Otherwise, they will not properly insulate the external connections
to the instrument and pose a shock hazard that could cause serious injury to the user.
Input/output connectors
The Keithley Instruments Model 2657A uses high-voltage triaxial connectors for input and output
connections to devices under test (DUTs) as shown in the following figure (titled Model 2657A
input/output connectors).
A triaxial cable can be removed from the rear panel by turning the cable's connector counterclockwise
and pulling it off the rear panel.
