Les transcepteurs de signaux vectoriels de NI combinent un générateur de signaux vectoriels et un analyseur de signaux vectoriels, avec un circuit FPGA programmable par l’utilisateur pour assurer des fonctions de contrôle et de traitement du signal en temps réel. Les utilisateurs ont constaté des améliorations d’un facteur 10 à 100 au niveau du temps de test dans des applications comme l’asservissement en puissance pour le test d’amplificateurs de puissance en tirant parti de la vitesse, du traitement déterministe et de l’architecture intrinsèquement parallèle du FPGA. Construit autour de l’architecture LabVIEW RIO de NI, le transcepteur de signaux vectoriels allie la souplesse de la programmation et les tout derniers matériels RF pour révolutionner le test des technologies mobiles. Le modèle NI PXIe-5646R offre 200 MHz de bande passante complexe via une fréquence d’échantillonnage de 250 Méch.\/s, ce qui correspond à une vitesse de transfert de données plus de huit fois supérieure à celle d’une trame radio LTE standard. Pour toutes ces raisons, le transcepteur de signaux vectoriels convient particulièrement aux toutes dernières techniques de conception et de test, telles que la prédistortion numérique et l’envelope tracking.<\/p>\n

Le matériel NI PXIe-5646R est piloté par le logiciel de conception de systèmes LabVIEW<\/a> et offre la plate-forme idéale pour relever les défis de la conception et du test des systèmes modernes.<\/p>\n
