1. An apparatus for testing a cable, the cable having a plurality of cable connectors, each cable connector having a plurality of electrical contacts, and the cable having a plurality of electrical paths between the electrical contacts, the apparatus comprising:

  • a. a user interface unit for receiving input from a user and providing output to the user;

    b. a control unit connected to said user interface unit and responsive to said user interface unit, comprising (1) plurality of testing means, operating independently from one another, each being connected to a different plurality of the cable'"'"'s electrical contacts, for (A) selectively applying a test signal to any selected one of said plurality of said electrical contacts, (B) selectively measuring a response signal at any one of said plurality of said electrical contacts, (C) providing data representative of an expected response signal at each of said plurality of electrical contacts, and (D) comparing said measured response signal with said data representative of said expected response signal, to derive data representative of the result of such comparison; and

    (2) communication means, connected between said user interface unit and said plurality of testing means, for transferring signals between said user interface means and said testing means; and

    c. a dynamic stimulation unit for stimulating the cable at a plurality of frequencies simultaneously.
