Sense setting
To make the connections shown in 4200A-SCS signal paths (on page A-17), you must select remote
sensing.
When remote sensing is selected, the rows and columns are paired together as follows:
Row A (force) paired with row B (sense)
Column 1 (force) paired with column 2 (sense)
Row E (force) paired with row F (sense)
Column 3 (force) paired with column 4 (sense)
When the FORCE matrix switches are closed by the ConnectPins user module, the SENSE matrix
switches are also closed.
For local sensing (2-wire), the connections from the SENSE terminals of the 4200A-SCS are not
used.
See Connection scheme settings (on page A-12) for details on local and remote sensing.
Connection setting
The row-column setting must be used when connecting instrumentation to matrix rows, as shown in
4200A-SCS signal paths (on page A-17
).
The maximum number of rows available to the test system is eight. If instrumentation needs more
than eight pathways, they must be connected to matrix columns, and the instrument card setting must
be used.
The figure below shows a test system with both the instruments and the DUT connected to matrix
columns.
See Connection scheme settings (on page A-12) for details on the row-column and instrument card
settings.
