Abstract
A cable tester tests cable to determine a cable status. The cable status includes an open status, a normal status and a short status. A pretest module senses activity on the cable and selectively enables testing based on said sensed activity. A test module is enabled by the pretest module, transmits a test pulse on the cable, measures a reflection amplitude and calculates a cable length. The test module determines the cable status based on the measured amplitude and the calculated cable length.
