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 ...

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 ...

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 ...

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 ...

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 ...

For certain high-security devices, such as card readers, ATMs, and hardware security modules, normal physical security isn’t enough – they need to wipe out their sensitive data if someone starts ...
