Abstract
A computer-based method and computer-readable medium containing computer-executable instructions for assimilating data collected by a time domain reflectometer and displaying more than two waves representing reflections of a pulse on conductors is provided. The method includes a means for wave reversal, wave shifting, multi-wave display, segmented velocity of propagation adjustment, multi-cursor option multi-flagging options and calculating of the total length of wet cable. The combination of these functions provides a highly accurate means for identifying the location of splices, faults, corrosion, cable damage and other anomalies that are typically found on any length of conductor cable. The ability of this method to display a greater number of waves simultaneously adds additional benefit to a technician attempting to locate particular anomalies with multi-conductor cables.
