Abstract :
A TDR setup for measuring differential transmission lines is modeled using both 2D quasi-static and 3D full-wave tools. We investigate the interaction between the coaxial probe and structure, explain parasitic effects, and show why a single-ended probe cannot be used to directly measure the characteristic impedance
