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 ?

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.
