A time-domain reflectometer (TDR) is an electronic instrument used to determine the characteristics of electrical lines by observing reflected waveforms. It can be used to characterize and locate faults in metallic cables (for example, twisted pair wire or coaxial cable). It can also be used to locate discontinuities in … See more A TDR measures reflections along a conductor. In order to measure those reflections, the TDR will transmit an incident signal onto the conductor and listen for its reflections. If the conductor is of a uniform See more These traces were produced by a time-domain reflectometer made from common lab equipment connected to approximately 100 feet (30 m) of coaxial cable having a characteristic impedance See more Time domain reflectometers are commonly used for in-place testing of very long cable runs, where it is impractical to dig up or remove what may be a kilometers-long cable. They are indispensable for preventive maintenance of telecommunication lines, … See more If the far end of the cable is shorted, that is, terminated with an impedance of zero ohms, and when the rising edge of the pulse is launched down the cable, the voltage at the launching point "steps up" to a given value instantly and the pulse begins propagating … See more • Frequency domain sensor • Murray loop bridge • Noise-domain reflectometry See more • Radiodetection Extended Training – ABC's of TDR's • Work begins to repair severed net • Time Domain Reflectometry Theory (PDF), Application Note, Keysight Technologies, 31 May 2013, AN-1304-2, archived (PDF) from the original on 9 October 2024, … See more WebDec 14, 2024 · In this article.
