Abstract

La présente invention concerne un procédé et un dispositif d'étalonnage de canal, configurés pour exécuter un étalonnage de canal sur un dispositif de balayage de faisceau. Le dispositif d'étalonnage de canal comprend : un canal d'étalonnage, et une première sonde et une seconde sonde connectées au canal d'étalonnage et placées sur un sous-réflecteur. Le canal d'étalonnage comprend un récepteur radiofréquence, un émetteur radiofréquence, et un duplexeur. La première sonde est dirigée vers un centre d'un réseau d'alimentation carré. La seconde sonde est dirigée vers un centre d'un réseau formé par 4 quelconques sources d'alimentation adjacentes dans le réseau d'alimentation carré.
