Introduction
This section contains information about connecting and configuring the 4200A-SCS.
Details for the Keithley pulse cards are provided in the
Pulse measure and pulse generator units
page 5-1) section of this manual.
Basic source-measure connections
Basic information on connecting source-measure units (SMUs), the preamplifier, and the ground unit
to devices under test (DUTs) is described in this section.
Maximum signal limits
The 4200A-SCS is provided with an interlock circuit that must be positively activated in
order for the high voltage output to be enabled. The interlock helps facilitate safe operation
of the equipment in a test system. Bypassing the interlock could expose the operator to
hazardous voltages that could result in personal injury or death.
Asserting the interlock allows the SMU and preamplifier terminals to become hazardous,
exposing the user to possible electrical shock that could result in personal injury or death.
SMU and preamplifier terminals should be considered hazardous even if the outputs are
programmed to be low voltage. Precautions must be taken to prevent a shock hazard by
surrounding the test device and any unprotected leads (wiring) with double insulation for
250 V, Category O.
