Electromagnetic compatibility (EMC) - Part 4-41: Testing and measurement techniques - Broadband radiated immunity tests

IEC 61000-4-41:2024 relates to broadband radiated disturbances generated by, for example, communication devices or services, transmitters or industrial electromagnetic sources or any other devices capable of generating such a signal.
The object of this document is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to broadband radiated electromagnetic fields.
This document specifies testing in the frequency ranges above 80 MHz, limited only by the capabilities of commercially available test instrumentation.
It forms Part 4-41 of IEC 61000. It has the status of a basic EMC publication in accordance with IEC Guide 107.

Compatibilité électromagnétique (CEM) - Partie 4-41: Techniques d'essai et de mesure - Essais d'immunité aux rayonnements à large bande

IEC 61000-4-41:2024 concerne les perturbations rayonnées à large bande générées, par exemple, par des dispositifs ou des services de communication, des émetteurs ou des sources électromagnétiques industrielles, ou tout autre dispositif capable de générer un tel signal.
Le présent document a pour objet d'établir une référence commune d'évaluation des performances en matière d'immunité des matériels électriques et électroniques soumis à des champs électromagnétiques rayonnés à large bande.
Le présent document spécifie les essais dans les plages de fréquences au-dessus de 80 MHz, limitées uniquement par les capacités des instruments d'essai disponibles dans le commerce.
Elle constitue la Partie 4-41 de l'IEC 61000. Elle a le statut d'une publication fondamentale en CEM conformément au Guide 107 de l'IEC.
