How does a time domain reflectometer work
http://tscm.com/riprcop.html WebThe calibration of a reflectometer becomes critical when reflectance values very close to unity (perfect reflectance) are to be measured. Refined methods can be used to optimize such calibration procedures; for example, one may use an optical setup where one can alternately measure the optical power of light reflected at the sample and the power of …

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 a … 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 of 50 ohms.
