TIME DOMAIN REFLECTOMETER (TDR)


Meaning of TIME DOMAIN REFLECTOMETER (TDR) in English

An electronic instrument used to characterize and locate faults in metallic cables ( e.g., twisted pair, coax). Note 1: A TDR transmits a fast rise time pulse along the conductor. The resulting reflected pulse is measured at the input as a function of time and displayed on the instrument or plotted, as a function of cable length. Note 2: A TDR may be used to verify cable impedance characteristics, splice and connector location and associated losses, and estimate cable lengths.
