A system for testing a communications device includes a portable wireless communications device comprising a transmitter for transmitting an RF signal. A monitoring device receives the RF signals from the portable wireless communications device and analyzes the RF signals to determine total radiated power emitted from the transmitter. An adaptive antenna equivalent circuit is coupled to the transmitter. A connection line extends between the adaptive antenna equivalent circuit and the monitoring device. The adaptive antenna equivalent circuit has an equivalent antenna impedance matched to the portable wireless communications device and the connection line and monitoring device based on transmit frequency to ensure that total radiated power of the RF signals is transmitted from the transmitter to the monitoring device.
L'invention concerne un système permettant de mettre à l'essai un dispositif de communications. Le système comprend un dispositif de communications mobiles sans fil muni d'un émetteur pour transmettre un signal RF. Un dispositif de surveillance reçoit les signaux RF du dispositif de communications mobiles sans fil et les analyse pour déterminer la puissance totale de rayonnement émise par l'émetteur. Un circuit équivalent d'antenne adaptative est couplé à l'émetteur. Un câble de connexion passe entre le circuit équivalent d'antenne adaptative et le dispositif de surveillance. Le circuit équivalent d'antenne adaptative comporte une impédance d'antenne équivalente adaptée au dispositif de communciations mobiles sans fil, au câble de connexion et au dispositif de surveillance selon la fréquence d'émission pour veiller à ce que la puissance totale de rayonnement des signaux RF soit transmise de l'émetteur au dispositif de surveillance.
