Patent ID: 7626398

Claim:
A system for isolating faults associated with one or more electronic assemblies interconnected to each other by a bundle of separated electrical wires each of which is terminated in a pin of at least one connector, said system comprising; an adaptor having an acceptor for each of said connectors, said acceptor further comprising terminals that are connected to said pins of said connectors; a signal generator providing an output; and a selector having an output and an input connected to receive said output of said signal generator, said selector having electronic switching for selectively and separately connecting its output to said terminals of said acceptor, said selector further comprises: an array of probes of a first predetermined number electronically connected to said terminals of said acceptors; a matrix switch having contacts of a second predetermined number equal to said first predetermined number of said array of probes and electronically connected thereto; a first peripheral interface adaptor responsive to a first control signal for electronically connecting to said contacts of said matrix switch and being responsive to a second control signal for electronically connecting to display equipment; a second peripheral adaptor responsive to a third control signal for electronically connecting to a signal generator and being responsive to a fourth control signal for electronically connecting to measurement instrumentation; said third and fourth control signals also respectively connecting said first peripheral adaptor to said signal generator and to said measurement instrumentation; and a microprocessor generating said first, second, third and fourth control signals and having an output comprising said output of said selector.
