Model 4200A-SCS Parameter Analyzer Reference Manual Appendix A: Using switch matrices
The 4200A-SCS automatically selects the first available rows to make connections to the DUT. In
this example, rows A through D are the first available rows.
The following shows 4200A-SCS signal paths through a 3-pole 7071 matrix card using remote
sensing. Note that for this configuration, each FORCE and SENSE connector does not use a
separate path (row). Unlike the configuration shown in 4200A-SCS signal paths (on page A-17), each
FORCE/SENSE connector pair is routed through a single 3-pole matrix switch. Since row pairing is
not required, the local sense setting must be used.
For two-wire local sense connections, do not use the SENSE connectors of the 4200A-SCS.
To avoid high voltage exposure that could result in personal injury or death, whenever the
interlock of the 4200A-SCS is asserted, the FORCE and GUARD terminals of the SMUs and
preamplifier should be considered to be at high voltage, even if they are programmed to a
non-hazardous voltage current.
See Connection scheme settings (on page A-12) for details on sense settings.
