Comment les meilleurs analyseurs de spectre portables et les récepteurs radio actuellement disponibles sur le marché se départagent-ils dans le cadre d’un test comparatif direct ? En optant pour un challenge neutre et juste dans des conditions analogues. Et, surtout, quel appareil mène la course dans le domaine des disciplines-clés « sensitivity » et « harmonics », « intermodulation » et « dynamic range » ? Narda STS a récemment publié un clip vidéo comparatif sur son canal YouTube. Cette présentation audiovisuelle instructive de 20 minutes répond à toutes les questions en son et images.
