D\u00e9finition d’un analyseur logique num\u00e9rique<\/strong><\/h2>\n\n\n\n
Un analyseur logique num\u00e9rique<\/strong> est un outil de mesure \u00e9lectronique permettant de capturer, visualiser et analyser des signaux num\u00e9riques<\/strong> (tout-ou-rien) sur plusieurs canaux simultan\u00e9ment. Contrairement \u00e0 un oscilloscope (adapt\u00e9 aux signaux analogiques), il se focalise sur les \u00e9tats logiques (HIGH\/LOW<\/strong>, 0\/1<\/strong>) et le d\u00e9codage de protocoles num\u00e9riques.<\/p>\n\n\n\n
PulseView : Pr\u00e9sentation et Fonctionnalit\u00e9s<\/strong><\/h3>\n\n\n\n
PulseView<\/strong> est un logiciel libre et open-source<\/strong> (GPL) con\u00e7u pour fonctionner avec des analyseurs logiques et oscilloscopes USB bas co\u00fbt. Il fait partie du projet sigrok<\/strong> et permet de visualiser, capturer et analyser des signaux num\u00e9riques et analogiques.<\/p>\n\n\n\n
