Metallic communication cables test methods - Part 1-1 : electrical - Measurement of the pulse/step return loss in the frequency domain using the Inverse Discrete Fourier Transformation (IDFT)

Le présent document décrit un essai qui détermine la régularité d'impédance des câbles pour fréquences radioélectriques (RF) en mesurant la perte par réflexions dans le domaine fréquentiel. Cette mesure est effectuée en utilisant un analyseur vectoriel de réseaux équipé d'un mesureur de réflexion (pont) et en transposant les résultats obtenus dans le domaine temporel en utilisant la Transformée Inverse de Fourier Discrète (TIFD) .
