Abstract
Aspects of the present disclosure provide for a cable tester that tests a cable to determine the cable length. The cable tester can include a clock generator that generates a clock that has clock period that is a multiple of the data symbol period and a signal generator that injects the training signal, which can be synchronous with the clock, into the cable. The cable tester can also include a receiver that samples the returned signal from the cable and adaptively filters the returned signal based on the training signal and a controller that determines the cable length from the adaptive filter tap coefficients.
