In a radio loop-back test system for a radio apparatus in which a transmitter (15) transmits a first radio signal in response to a transmission signal and which a receiver (16) receives a second radio signal to produce a reception signal, a comparing portion (22) compares the reception signal with the transmission signal to produce a comparison result signal. An interference detection portion (23) detects whether or not the reception signal has an interference component unrelated with the first radio signal. The interference detection portion produces an interference detection signal when the reception signal has the interference component. The comparison result signal is controlled by an output control portion (24) in accordance with presence and absence of the interference detection signal.

Un système de vérification d'un signal radio en boucle pour un appareil radio dans lequel un émetteur (15) transmet un premier signal radio en réponse à un signal de transmission et dans lequel un récepteur (16) reçoit un deuxième signal radio dans le but de produire un signal de réception. Un module de comparaison (22) compare le signal de réception et le signal de transmission pour produire un signal de résultat de comparaison. Un module de détection d'interférence (23) vérifie si le signal de réception possède une composante d'interférence non reliée au premier signal radio. Si le signal de réception en possède une, le module produit un signal de détection d'interférence. Le signal de résultat de comparaison est contrôlé par un module de contrôle des sorties (24) selon la présence et l'absence du signal de détection d'interférence.
