CISPR 16-2-3:2016
(Main)Specification for radio disturbance and immunity measuring apparatus and methods - Part 2-3: Methods of measurement of disturbances and immunity - Radiated disturbance measurements
Specification for radio disturbance and immunity measuring apparatus and methods - Part 2-3: Methods of measurement of disturbances and immunity - Radiated disturbance measurements
CISPR 16-2-3:2016 is available as CISPR 16-2-3:2016 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
CISPR 16-2-3:2016 specifies the methods of measurement of radiated disturbance phenomena in the frequency range of 9 kHz to 18 GHz. The aspects of measurement uncertainty are specified in CISPR 16-4-1 and CISPR 16-4-2. It has the status of a basic EMC publication in accordance with IEC Guide 107, "Electromagnetic compatibility - Guide to the drafting of electromagnetic compatibility publications". This fourth edition edition cancels and replaces the third edition published in 2010, its Amendment 1:2010 and its Amendment 2:2014. This edition constitutes a technical revision.
Spécifications des méthodes et des appareils de mesure des perturbations radioélectriques et de l'immunité aux perturbations radioélectriques - Partie 2-3: Méthodes de mesure des perturbations et de l'immunité - Mesurages des perturbations rayonnées
La CISPR 16-2-3:2016 spécifie les méthodes de mesure de phénomènes perturbateurs rayonnés, dans la plage de fréquences de 9 kHz à 18 GHz. Les aspects de l'incertitude de mesure sont spécifiés dans les normes CISPR 16-4-1 et CISPR 16-4-2. Elle a le statut de publication fondamentale en CEM conformément au Guide 107 de l'IEC, "Compatibilité électromagnétique - Guide pour la rédaction des publications sur la compatibilité électromagnétique". Cette quatrième édition annule et remplace la troisième édition parue en 2010, l'Amendement 1:2010 et l'Amendement 2:2014. Cette édition constitue une révision technique.
