Abstract

A system for multichannel analysis and testing is provided. The analysis system includes a modulated electromagnetic source having two or more wavelengths or frequency, a multichannel system having a plurality of signals, coupled to the modulated electromagnetic source, a switch for selecting more than one of the signals, and a time domain analyzer for measuring delay between one of the signals and more than one of the other signals to determine system characteristics. The time domain analyzer measures delays between the transitions of a first signal, measures delay between the transition of a first signal and the transition of each of many of the other signals for many signals, and then generates a matrix of the measurements. The matrix is analyzed to determine system characteristics.
