Abstract: A system for testing complex circuitry primarily in large scale integration where a great number of inputs and outputs must be tested and the internal circuitry is inaccessible. The test system has a weighted random number generator which applies a test signal to some input terminals of the logic under test more frequently than others. A particular input terminal to the logic under test can be accessed in proportion to the circuit switching activity associated with accessing that particular terminal.

Abstract: A hybrid connector system comprising a special jack, a standard coaxial plug effective to make contact with the jack in one mode when inserted therein, and a wire pair plug operable to engage the special jack in another mode when plugged thereinto, the wire pair plug element being adaptable to, or configured especially for, use with shielded twisted pair cables, unshielded twisted pair cables, or ordinary telephone lines. The jack or socket member has first second and third concentric contact members, two of which are arranged to engage respectively, the central and shell contacts of a coaxial cable plug. The third of the contact elements of the socket member is interposed between the first and second contact elements, and the three contact elements are positioned to engage corresponding contact elements of the special plug which, when inserted into the socket completes connection to first and second ones of a wire pair and, optionally, a shield of such wire pair. Switch means are arranged to be operated between open and closed conditions by one of the kinds of plugs which the hybrid jack is designed to receive.
