Section 7: Keithley CONfiguration Utility (KCON)
Instrument Connection Scheme area
The following Instrument Connection Scheme selections define the scheme for interconnections
between the instruments, the switch-matrix rows and columns, and the test system (prober or test
fixture).
•
Row-Column (instruments to rows and prober/test fixture to columns) or Instrument Card
(both instrument and prober/test fixture to columns)
•
Local Sense (connections only to instrument FORCE terminals) or Remote Sense
(connections both to instrument FORCE and SENSE terminals)
These selections are discussed below in more detail:

Instrument Card
7-32
With the Row-Column scheme, instruments are connected to switch-
matrix rows, and prober/test fixture pins are connected to switch-matrix
columns. This connection scheme is the simplest. Instrument signals
can route to prober/test-fixture pins through only one matrix card, as
illustrated in
number of external instruments. If you need to connect numerous
external instruments to the prober/test-fixture, use the Instrument Card
scheme.

With the Instrument Card scheme, both instruments and prober/test-
fixture pins are connected to the columns of the switch matrix.
Instrument signals route to the prober/test-fixture pins through two or
more matrix cards, as illustrated in
scheme can support large systems with numerous instruments by
removing the eight-row instrument connection limitation.
