L\u2019architecture \u00e0 deux quadrants leur permet de fonctionner \u00e0 la fois comme une source et comme une charge. Leurs temps de recouvrement courts permettent de traiter les changements de charges rapides qui se produisent par exemple lorsqu’un dispositif commute du mode veille au mode transmission. La nouvelle s\u00e9rie d’alimentations R&S NGL200de Rohde\u2009&\u2009Schwarz s’adresse tout particuli\u00e8rement aux utilisateurs des secteurs des communications mobiles et de l’IoT. Les mod\u00e8les une voie R&S NGL201 et deux voies R&S NGL202 d\u00e9livrent une puissance de sortie de 60 W par voie. Les voies de sortie sont flottantes, isol\u00e9es galvaniquement et prot\u00e9g\u00e9es contre les surcharges et les courts-circuits. Les alimentations peuvent r\u00e9cup\u00e9rer la puissance de mani\u00e8re contr\u00f4l\u00e9e, leur permettant de simuler les caract\u00e9ristiques sp\u00e9cifiques d’une batterie. Cette s\u00e9rie fixe \u00e9galement de nouveaux standards avec ses larges \u00e9crans tactiles capacitifs haute r\u00e9solution. L’interface utilisateur optimis\u00e9e est tr\u00e8s intuitive et les ventilateurs contr\u00f4l\u00e9s en temp\u00e9rature garantissent un fonctionnement tr\u00e8s silencieux. Des fonctions \u00e9volu\u00e9es de protection prot\u00e8gent le dispositif sous test et l’alimentation en cas de d\u00e9faut.<\/p>\n

Temps de recouvrement de charge tr\u00e8s rapide<\/b>
\nCes alimentations sont utilis\u00e9es pour alimenter des dispositifs IoT et d’autres syst\u00e8mes fonctionnant sur batterie ou pour tester des semi-conducteurs devant \u00eatre capables de traiter des changements de charges passant de quelques \u00b5A \u00e0 plusieurs amp\u00e8res, sans chutes ou pics de tension. Avec leurs temps de recouvrement de charge rapides inf\u00e9rieurs \u00e0 30 microsecondes et un pic de d\u00e9passement minimal, ces alimentations sont id\u00e9ales pour de telles t\u00e2ches.<\/p>\n

Lectures avec une r\u00e9solution jusqu’\u00e0 6\u200a\u00bd chiffres<\/b>
\nAvec une r\u00e9solution jusqu’\u00e0 6\u200a\u00bd chiffres pour les mesures de tension, de courant et de puissance, la s\u00e9rie R&S NGL200 est id\u00e9ale pour la caract\u00e9risation de dispositifs poss\u00e9dant de faibles consommations de puissance en mode veille et un courant \u00e9lev\u00e9 en fonctionnement \u00e0 pleine charge. La plage enti\u00e8re de mesure est couverte sans devoir changer de gamme, ce qui acc\u00e9l\u00e8re les mesures. Dans de nombreux cas, un multim\u00e8tre num\u00e9rique suppl\u00e9mentaire n’est plus n\u00e9cessaire. Cela permet d’\u00e9conomiser de la place et de l’argent, tout en simplifiant les configurations de test.<\/p>\n

Interfaces et options <\/b>
\nEn plus des voies de sorties, la s\u00e9rie R&S NGL200 propose des connecteurs pour les lignes sense. Les interfaces USB et LAN sont install\u00e9es en standard pour le contr\u00f4le \u00e0 distance. L’option R&S NGL-K102 ajoute la prise en charge WLAN. Des entr\u00e9es et sorties num\u00e9riques sont disponibles avec l’option R&S NGL-K103, et l’option mat\u00e9rielle R&S NGL-B105 fournit une interface GPIB (IEEE-488).<\/p>\n
