Abstract

L'invention concerne les techniques de mesures électriques. Le dispositif de mesure faisant l'objet de l'invention est caractérisé notamment en ce qu'il comporte un compteur binaire réversible 11, un convertisseur numérique-analogique 12 aux entrées duquel sont connectées les sorties dudit compteur, la sortie dudit convertisseur étant reliée par l'intermédiaire d'un commutateur 7 à l'entrée non inverseuse 6 de l'amplificateur opérationnel 4, un bloc 13 de commande d'inversion du compteur binaire réversible Il, dont les sorties sont connectées aux entrées dudit compteur et dont l'entrée est connectée à la sortie de l'amplificateur opérationnel 4. L'invention peut être utilisée en particulier pour mesurer les paramètres électriques des résonateurs à quartz et piézo-céramiques.
