Abstract

L'invention concerne les mesures d'impédances électriques. Un circuit d'entrée pour un dispositif destiné à mesurer une impédance Zx par comparaison avec une impédance de référence Z, comprend notamment un transformateur de couplage T qui applique un signal haute fréquence aux deux impédances branchees en série; deux interrupteurs S1 , S2 qui connectent alternativement à la masse les bornes opposées de l'enroulement secondaire du transformateur, et un amplificateur branché à la borne commune aux deux impédances. Application aux impédancemètres pour les mesures en haute fréquence.
