Abstract:
1. A system for testing a communications connector having a plurality of contact pairs comprising: an oscillator adapted to produce a test signal; a switch array having first and second switches, coupled to said oscillator and adapted to receive said test signal; a first amplifier coupled to said switch array and adapted to amplify said test signal; a second amplifier coupled to said switch array and adapted to amplify said test signal; a tester comprising a first contact pair connected to a first test signal input path and a second contact pair connected to a second test signal input path, said first contact pair adapted to receive said test signal from said first amplifier via said first test signal input path, said second contact pair adapted to receive said test signal from said second amplifier via said second test signal input path; a first near-end detector coupled to said first test signal input path via a first near-end directional coupler adapted to couple signal flowing in a direction opposite the direction of test signal flow, said first near-end detector detecting a return loss signal and generating a first near-end detector signal; a second near-end detector coupled to said second test signal input path via a first near-end directional coupler adapted to couple signal flowing in a direction opposite the direction of test signal flow, said second near-end detector detecting a near-end crosstalk signal and generating a second near-end detector signal; a near-end analog-to-digital converter adapted to receive said first near-end detector signal and said second near-end detector signal, to convert the first near-end detector signal to a converted first near-end detector signal, and to convert the second near-end detector signal to a converted second near-end detector signal; and a microcontroller adapted to receive said converted first near-end detector signal and said converted second near-end detector signal and to generate a first contact pair return loss value based on said converted first near-end detector signal and further to generate a first and second contact pair near-end crosstalk value based on said converted second near-end detector signal.
