Abstract

Le système pour analyseur de spectres de récepteur à exploration est un système de surveillance du spectre d'énergie R.F. sur un réseau de câblage en amont, le but dudit système étant de faire fonctionner un groupe de modems câbles dans des bandes de fréquences qui présentent le moins d'interférences. L'analyseur de spectres examine l'ensemble du spectre en aval (généralement 5 - 42 MHz) pour déterminer le niveau de bruits à chaque fréquence, et puis, il apprécie ces données par rapport aux conditions de fonctionnement du moment (par exemple, des taux d'erreurs binaires) pour déterminer la meilleure fréquence possible d'autres canaux de modems sur un noeud en amont, et enfin il attend qu'une condition favorable au déclenchement se produise, celle-ci indiquant qu'un changement de fréquences des modems est requis.
