A time domain reflectometer (TDR) measures reflections along a cable. It is similar in principle to radar. To measure those ...

A TDR sees each increment of cable, say each foot, as the equivalent electrical circuit shown in Figure 1. The combination of these components is referred to as the characteristic impedance (Z0) of ...

Wave propagation characteristic of single phase medium voltage MV cross-linked-polyethylene (XLPE) cable is determined by using Time Domain Reflectometry (TDR). It involves sending electrical pulse ...

Almost a decade ago W2AEW posted a video on his YouTube channel showing a cheap and easy to build pulse generator for time domain reflectometry (TDR), consisting of only a simple hex inverter with ...

This circuit is from Tomi Engdahl's page. It describes a nifty little TDR that, when combined with a regular oscilloscope, can be used to find discontinuities on long runs of cables.
