Measurement of Transmission Line Parameters using the Time Domain Technique

Abstract

Time domain spectroscopy in reflection mode has been used to determine line parameters like Impedance (Z), peak percent reflection (ρ_max), distance from the reference plane to the narrow trace discontinuity (I) etc in the frequency range of 10 MHz to 10 GHz. Differential mode impedance (Z^dit) and Common mode impedance (Z^com) of two uncoupled lines are also measured using fast differential Time Domain Reflectometry (TDR) technique.
