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. This circuit is ...

A time domain reflectometer (TDR) measures reflections along a cable. It is similar in principle to radar. To measure those reflections, the TDR transmits an incident signal into the cable and watches ...

Time-domain reflectometry (TDR) is a technique that measures and displays the impedance of a network (cable, filter, and so on) over time. Traditionally, this is done with a device that generates very ...

With the handheld devices TDR 500 and TDR 510, BAUR Prüf- und Messtechnik GmbH presents new and robust time domain reflectometers for length determination and fault location in power and data cables.

Offering a choice of five output impedances, the TDR2010 dual-channel time-domain reflectometer (TDR) from Megger locates faults on all metallic cables, including twisted-pair wires and coaxial cables ...

“Time-domain reflectometry” sure sounds like something that needs racks of expensive equipment to accomplish. In reality, TDR is just measuring the time between injecting a pulse into a cable and ...

The handheld CFL510G time domain reflectometer (TDR) from Megger features a 2-ns pulse width that is said to virtually eliminate dead zones, letting the instrument accurately locate faults less than ...

The CFL510G time domain reflectometer (TDR) features a 2 ns pulse width that virtually eliminates dead zones. Designed to locate faults less than 3 ft from the point of connection, the IP54-rated TDR ...
