Utilizing Time Domain (TDR) Test Methods

Time Domain Reflectometry (TDR) is a very useful tool for designing transitions such as the transition between coaxial connectors and PC boards. The TDR function will display the impedance over time showing the place and nature of discontinuities that are due to impedance changes. This paper discusses the aspects of TDR measurements that are relevant to the analysis of a transition.
