Abstract
An adjustable impedance-correcting delay line adapted to form a standard line for providing an adjustable group delay time for measurement purposes or the like in which a plurality of different delay networks including coaxial segments of different lengths with or without damping compensating amplifiers can be selectively connected in the cascade or shunted. A bridge circuit can be provided with fundamental damping and delay time for bridging with the standard delay line where difference measurements are of interest.
