Abstract[English]
A test and measurement system includes a proximity coupling device to transmit a modulated carrier signal and a proximity integrated circuit card to load modulate the transmitted modulated carrier signal and generate a modulated subcarrier signal on the wireless carrier signal. A test and measurement instrument acquires the modulated carrier signal and includes a phase-aligned subcarrier demodulator to demodulate the carrier signal including the modulated subcarrier signal. A demodulator detects commands and responses in the modulated carrier signal, removes the commands, and identifies a correlation index for each response. Each correlation index indicates a phase of the modulated carrier signal of the corresponding response relative to a replica carrier signal. The demodulator adjusts the phase of the replica carrier signal based on the correlation index for each response and down converts each response using the phase-aligned replica carrier signal. The modulated subcarrier signal is low pass filtered to demodulate response.[French]
Un système de test et de mesure comprend un dispositif de couplage de proximité pour transmettre un signal de porteuse modulé et une carte de circuit intégré de proximité pour moduler la charge du signal de porteuse modulé transmis et générer un signal de sous-porteuse modulé sur le signal de porteuse sans fil. Un instrument de test et de mesure acquiert le signal de porteuse modulé et comprend un démodulateur de sous-porteuse aligné en phase pour démoduler le signal de porteuse comprenant le signal de sous-porteuse modulé. Un démodulateur détecte des commandes et des réponses dans le signal de porteuse modulé, élimine les commandes et identifie un indice de corrélation pour chaque réponse. Chaque indice de corrélation indique une phase du signal de porteuse modulé de la réponse correspondante par rapport à un signal de porteuse de réplique. Le démodulateur ajuste la phase du signal de porteuse de réplique sur la base de l'indice de corrélation pour chaque réponse et convertit à la baisse chaque réponse à l'aide du signal de porteuse de réplique aligné en phase. Le signal de sous-porteuse modulé est filtré passe-bas pour démoduler une réponse.
