Abstract

Le système permet d'enregistrer la transformée d'un signal appliqué à l'entrée d'un analyseur de spectre délivrant sur une sortie X le signal de balayage du tube et sur une sortie Y le signal fonction de l'amplitude du spectre. Le signal issu de Y est appliqué à un convertisseur A/N qui comporte un registre de sortie connecté à une mémoire, il est aussi appliqué à un comparateur qui déclenche une temporisation si Y est inférieur à un seuil. Après la temporisation, un ordre de transfert du registre à la mémoire est émis, suivi d'un signal RAZ. Utilisable notamment pour obtenir la réponse en fréquence d'un moyen de transmission, tel qu'une fibre optique.
