Abstract

L'invention concerne un affaiblisseur à échelons. Cet affaiblisseur se caractérise par une pluralité de branches 1 à 5 reliées d'un côté à une borne de sortie 23 et de l'autre côté à des commutateurs 17 à 21 qui permettent de relier une branche 17 à une borne d'entrée 15 et les autres branches 18 à 21 à un potentiel de référence. Application : entrée d'amplificateur d'oscilloscope.
