What is Time Domain Reflectometers?

A Time Domain Reflectometer (TDR) is an electronic instrument used to locate faults, measure cable lengths, and characterize impedance in metallic cables. It works by sending a pulse along the cable and analyzing the reflections. These reflections indicate changes in impedance caused by faults, connections, or cable terminations. TDRs are commonly used in telecommunications, networking, and aerospace industries for cable testing and maintenance.
