describes the test which determines the regularity of impedance of r.f. cables by measuring the return loss in the frequency domain using a vector network analyser equipped with a reflection test set (bridge) and transferring the results into the time domain by using the Inverse Discrete Fourier Transformation (IDFT). decrit un essai qui determine la regularite dimpedance des cables pour frequences radioelectriques (RF) en mesurant la perte par reflexions dans le domaine frequentiel. Cette mesure est effectuee en utilisant un analyseur vectoriel de reseaux equipe dun mesureur de reflexion (pont) et en transposant les resultats obtenus dans le domaine temporel en utilisant la Transformee Inverse de Fourier Discrete (TIFD).
