(Main)Cable assemblies, cables, connectors and passive microwave components - Screening attenuation measurement by the reverberation chamber method
Cable assemblies, cables, connectors and passive microwave components - Screening attenuation measurement by the reverberation chamber method
This standard describes the measurement of screening attenuation by the reverberation chamber measurement method, also called mode stirred chamber method. This standard is applicable to screening attenuation measurements of cable assemblies, cables, connectors, and passive microwave components, such as waveguides, phase shifters, diplexers/multiplexers, power dividers/combiners and etc. Modern electronic equipments have shown a demand for methods for testing screening attenuation performance of microwave components over their whole frequency range. Convenient measurement methods have existed for lower frequencies and components of regular shape. These measurement methods are described in IEC 62153 series standards. For much higher frequencies and for components of irregular shape, the reverberation chamber method should be used. Theoretically, the reverberation chamber method has no upper limit of the measurement frequency, but it is limited by the quality and sensitivity of the measurement system, and the lower limit of the measurement frequency is restricted by the size of the reverberation chamber.

IEC 61726:2022 décrit le mesurage de l'affaiblissement d'écran par la méthode de mesure de la chambre réverbérante, également appelée "méthode de la chambre à brassage de modes". Le présent document est applicable aux mesurages de l'affaiblissement d’écran des cordons, des câbles, des connecteurs et des composants hyperfréquence passifs, tels que les guides d'ondes, les déphaseurs, les diplexeurs/multiplexeurs, les répartiteurs/combineurs de puissance, etc. Cette quatrième édition annule et remplace la troisième édition parue en 2015. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a. reformulation de l’Article 1 "Domaine d’application"; b. remplacement de l’IEC TS 62153-4-1 par l’IEC 62153 (toutes les parties) à l’Article 2; c. ajout de la définition de l’affaiblissement d’écran en 3.1; d. ajout de l’Article 4 "Principe de mesure de l’affaiblissement d’écran"; e. ajout des descriptions de certains montages d’essai, comme le synthétiseur de fréquences, l’analyseur de spectre, le moteur pas-à-pas, les dispositifs de liaison et le système d’échantillonnage etc. à l’Article 5; f. ajout de l'Article 6 "DUT"; g. reformulation de l’Article 7 "Procédure de mesure"; h. ajout de l’Article 8 "Notes d’avertissement"; i. ajout de l’Article 9 "Critère d’acceptation"; j. ajout de l’Article 10 "Informations à fournir dans la spécification appropriée".
Kabelski sestavi, kabli, konektorji in pasivne mikrovalovne komponente - Meritve zaslonskega slabljenja z metodo odmevne komore (IEC 61726:2022)
Ta standard opisuje meritve zaslonskega slabljenja z metodo odmevne komore, imenovano tudi metoda mešane komore.
Ta standard se uporablja za meritve zaslonskega slabljenja kabelskih sklopov, kablov, konektorjev in pasivnih mikrovalovnih komponent, kot so valovodi, preklopniki napetosti, diplekserji/multiplekserji, delilniki/združevalniki virov napajanja itd.
Sodobna elektronska oprema nakazuje potrebe po metodah za preskušanje učinkovitosti zaslonskega slabljenja mikrovalovnih komponent za celotno frekvenčno območje. Obstajajo priročne metode merjenja za nižje frekvence in komponente pravilne oblike. Te metode merjenja so opisane v skupini standardov IEC 62153. Za veliko višje frekvence in za komponente nepravilne oblike je treba uporabiti metodo odmevne komore. Metoda odmevne komore v teoriji nima zgornje meje merilne frekvence, ampak je omejena s kakovostjo in občutljivostjo merilnega sistema, spodnja meja merilne frekvence pa je omejena z velikostjo odmevne komore.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
