Time Domain Reflectometry—Case Studies in Electrical Failure Isolation

Time Domain Reflectometry (TDR) is an analysis technique for characterizing a transmission environment (PCB traces, cable assemblies, etc.) and identifying the physical location of defects or impedance discontinuities which can quickly narrow the focus of an investigation. This paper introduces the capability and presents several case studies spanning different applications where TDR was useful as a non-destructive analysis technique.
