Abstract
A cable tester tests cable and determines a cable pass/fail status. A pretest module senses activity on the cable and selectively enables testing based on the 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 cable status includes an open status, a short status, and a normal status. The test module determines the cable status of the cable based on the cable at least one of passing and failing A out of B cable tests. The test module determines the cable status for each of the B tests based on the measured amplitude and the calculated cable length.
