2023年10月26日 · A Time Domain Reflectometer (TDR) is a versatile and powerful diagnostic tool used to locate and identify faults in various types of transmission lines, such as coaxial cables, twisted pairs, and optical fibers.
Time Domain Reflectometry - an overview | ScienceDirect Topics
Time Domain Reflectometry is a measurement technique that determines the apparent relative permittivity of a material by measuring the travel time of a high-frequency electromagnetic wave through a wave-guide probe inserted into the material.
When compared to other measurement techniques, time domain reflectometry provides a more intuitive and direct look at the DUT’s characteristics. Using a step generator and an oscilloscope, a fast edge is launched into the transmission line under investigation.

A Time Domain Reflectometer is set up as shown in Figure 3. The step generator produces a positive going incident wave which is fed into the transmission system under test. The oscilloscope’s high imped- ance input bridges the transmission system at its junction with the step generator. The step travels
