Abstract

L'INVENTION CONCERNE LE TEST DES CIRCUITS ELECTRIQUES. UN APPAREIL DE TEST DE CIRCUITS ELECTRIQUES COMPORTE ESSENTIELLEMENT UN SELECTEUR 4 QUI SELECTIONNE SUCCESSIVEMENT CHAQUE POINT DE TEST DU CIRCUIT SOUS TEST 1, DES CONVERTISSEURS 6, 7 ET 8 QUI FOURNISSENT UN SIGNAL ANALOGIQUE REPRESENTATIF DE CHAQUE PARAMETRE MESURE, UN CONVERTISSEUR NUMERIQUE-ANALOGIQUE 10, ET UN CIRCUIT DE TEST 11 QUI COMPARE LA VALEUR MESUREE AVEC UNE VALEUR PROGRAMMEE QUI EST CONSERVEE DANS UNE MEMOIRE 14. APPLICATION AU CONTROLE AUTOMATIQUE DE CIRCUITS IMPRIMES.THE INVENTION CONCERNS THE TEST OF ELECTRIC CIRCUITS. AN ELECTRICAL CIRCUIT TEST EQUIPMENT ESSENTIALLY INCLUDES A SELECTOR 4 WHICH SUCCESSIVELY SELECTS EACH TEST POINT OF THE CIRCUIT UNDER TEST 1, CONVERTERS 6, 7 AND 8 WHICH PROVIDE AN ANALOGUE SIGNAL REPRESENTATIVE OF EACH DIGITAL CONVERTER-10, MEASUREMENT ANALOGUE PARAMETER 10, AND A TEST CIRCUIT 11 WHICH COMPARES THE MEASURED VALUE WITH A PROGRAMMED VALUE WHICH IS STORED IN A MEMORY 14. APPLICATION TO THE AUTOMATIC CONTROL OF PRINTED CIRCUITS.
