Topic:  Advances In Test Technology For Metal Cables
Dr. Robert Flake - UT Austin

A new generation of higher resolution TDR instruments for testing signal delay (electrical length) of metal cables is being developed in our laboratory. The instrument has been used to make measurements on an assortment of various cables including coaxial and TWP electrical interconnects. The major advance in precision obtained with this TDR is the result of the discovery of a non sinusoidal signal waveform that does not undergo dispersion during transmission on lossy dispersive transmission line interconnects. This special signal is employed as the test pulse in this new generation of cable TDRs. Total latency or electrical length measurements (with 10s of ppm resolution) of cable assemblies have recently been obtained in our laboratory.  This new TDR instrument using the shape preserving signal as the test pulse to measure the electrical length of a metal cable will be experimentally demonstrated during the presentation.
