CISPR 16-2-1:2008
(Main)Specification for radio disturbance and immunity measuring apparatus and methods - Part 2-1: Methods of measurement of disturbances and immunity - Conducted disturbance measurements
Specification for radio disturbance and immunity measuring apparatus and methods - Part 2-1: Methods of measurement of disturbances and immunity - Conducted disturbance measurements
CISPR 16-2-1:2008 specifies the methods of measurement of disturbance phenomena in general in the frequency range 9 kHz to 18 GHz and especially of conducted disturbance phenomena in the frequency range 9 kHz to 30 MHz. This second edition of CISPR 16-2-1 cancels and replaces the first edition (2003) and its Amendment 1 (2005) and constitutes a technical revision. CISPR 16-2-1:2008 includes significant technical changes with respect to the previous edition. In general, this new edition aims at reducing compliance uncertainty in correspondence with findings in CISPR 16-4-1. Guidelines are given on
- resonance-free connection of the AMN to reference ground,
- avoidance of ground loops, and
- avoidance of ambiguities of the test setup of EUT and AMN with respect to the reference ground plane.
In addition, terms are clarified, a new type of ancillary equipment (CVP) is applied, and a clarification for the use of the AAN and AMN on the same EUT is provided.
Spécifications des méthodes et des appareils de mesure des perturbations radioélectriques et de l'immunité aux perturbations radioélectriques - Partie 2-1: Méthodes de mesure des perturbations et de l'immunité - Mesures des perturbations conduites
La CISPR 16-2-1:2008 spécifie les méthodes de mesure des phénomènes perturbateurs en général, dans la gamme de fréquences de 9 kHz à 18 GHz et spécialement les perturbations conduites dans la gamme de fréquences de 9 kHz à 30 MHz. Cette deuxième édition de la CISPR 16-2-1 annule et remplace la première édition (2003) et son Amendement 1 (2005) et constitue une révision technique. La CISPR 16-2-1:2008 inclut des modifications techniques majeures par rapport à l'édition précédente. De manière générale, cette nouvelle édition a pour objectif de réduire l'incertitude de conformité, en connexion avec les conclusions de la CISPR 16-4-1. Des indications sont fournies sur:
- la connexion sans résonance de l'AMN à la masse de référence,
- la manière d'éviter les boucles de masses, et
- la manière d'éviter les ambiguïtés sur le montage d'essai de l'équipement en essai et de l'AMN par rapport au plan de masse de référence.
De plus, des termes sont clarifiés, un nouveau type d'équipement d'appoint est introduit, et des clarifications en vue de l'utilisation d'AAN et d'AMN sur le même équipement en essai sont fournies.
