A method of characterizing a section of a transmission line, in particular section which constitutes a connector or connectors of series connecting a measuring equipment has a cable

A method of characterizing a section of a transmission line, a reference signal being injected into the line and measure (301) time of the reflection of said reference signal in the line being carried out, said method comprising the steps of: • Applying a step of deconvolution (302) to said time measurement so as to generate a deconvolved temporal sequence comprising a plurality of amplitude peaks each corresponding to an impedance discontinuity, • removing (303) in the amplitude of at least one peak obtained, the contribution of at least one secondary rebound signal on an impedance discontinuity, • less, of the temporal position of each peak, a position of an associated impedance discontinuity in said line section , • Less (304), the amplitude of each peak, an estimate of the real part of the coefficient of reflection of a reflected wave on each discontinuity imped identified dence.
