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 ...

The AEMC Fault Mapper Pro is a hand-held graphical TDR (Time Domain Reflectometer) designed for identifying and locating faults on power cables, given access to one end only. The AEMC Fault Mapper Pro ...

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.

Test Coupon，是用来以 TDR (Time Domain Reflectometer 时域反射计) 来测量所生产的 PCB 的特性阻抗是否满足设计的要求，一般要控制的阻抗有单端线和差分对两种情况，所以 test coupon 上的走线线宽和线距(有差分对时)要与所要控制的线一样，最重要的是测量时接地点的位置。

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 ...

TDR (time-domain-reflectometry) measurements can provide a direct representation of the signal integrity of a cable or PCB (printed-circuit-board) trace and can analyze ICs’ performance and failure. A ...

All the components are easily obtained or manufactured. Any non-magnetic metal can be used for the probe. In this case, stainless steel was used. TDR Detailed Implementation To make a TDR measurement, ...

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 ...
