Time Domain Reflectometers
TDR (time-domain reflectometer) cable fault locators are electronic instruments that locate faults in metallic cables (such as a twisted wire). They use time-domain reflectometry (reflection of sound waves) to detect issues in cables. TDR cable fault locators are commonly used to locate issues in a connector, printed circuit board, or other electrical paths.
