CA 2261957

A method and apparatus for locating the source of noise ingress into a CATV system return path (16) by coupling a filter (18, 18') having a passband in the noise frequency bandwidth to the nodes between adjacent return path amplifiers {221, 22m, 22n). T'he filter (18, 18') is sequentially coupled to the nodes, working away from the CATV system headend (30). A signal level meter (50) or the like monitors the effect on the noise of coupling the filter (18, 18') to the nodes. When a node is reached at which coupling of the filter (18, 18') to the node no longer has any effect on the signal level in the node, the source of the noise is isolated in the node immediately preceding the node under test.

Procédé et appareil pour localiser la source d'entrée de bruit dans une voie de retour (16) d'un système de télévision à antenne collective, par le couplage d'un filtre (18, 18') dont la bande passante se trouve dans la largeur de bande de fréquences du bruit, aux noeuds situés entre les amplificateurs de voie de retour adjacents (221, 22m, 22n). Le filtre (18, 18') est couplé séquentiellement aux noeuds, fonctionnant loin de la tête de réseau (30) du système de télévision à antenne collective. Un dispositif de mesure de l'intensité du signal (50) ou similaire contrôle l'effet sur le bruit de couplage du filtre (18, 18') aux noeuds. Lorsqu'un noeud est atteint, au niveau duquel le couplage du filtre (18, 18') au noeud n'a plus d'effet sur l'intensité du signal dans ce dernier, la source du bruit est isolée immédiatement dans le noeud précédant le noeud contrôlé.
