Annotation of standard text IEC 61260-1-ed.1.0 :
IEC 61260-1:2014 specifies performance requirements for analogue, sampled-data, and digital implementations of band-pass filters. The extent of the pass-band region of a filters relative attenuation characteristic is a constant percentage of the exact mid-band frequency for all filters of a given bandwidth. An instrument conforming to the requirements of this standard may contain any number of contiguous band-pass filters covering any desired frequency range. Performance requirements are provided for two filter classes: class 1 and class 2. In general, specifications for class 1 and class 2 filters have the same design goals and differ mainly in the acceptance limits and the range of operational temperature. Acceptance limits for class 2 are greater than, or equal to, those for class 1. Maximum-permitted expanded uncertainties of measurement are also specified. Band-pass filters conforming to the performance requirements of this standard may be part of various measurement systems or may be an integral component of a specific instrument such as a spectrum analyser. This standard specifies the ranges of environmental conditions for operation of the filters. The required range depends on whether the instrument containing the filters is designed to be operated in a controlled environment or more generally in the field. Band-pass filters conforming to the requirements of this standard are capable of providing frequency-band-filtered spectral information for a wide variety of signals, for example, time-varying, intermittent or steady; broadband or discrete frequency; and long or short durations. This first edition of IEC 61260-1, future IEC 61260-2 and future IEC 61260-3, cancel and replace the first edition of IEC 61260 (1995) and its amendment 1 (2001). This edition constitutes a technical revision which includes the following significant technical changes with respect to the IEC 61260 (1995) and its amendment 1 (2001): - the single document in the first edition of IEC 61260 (1995) and its amendment 1 (2001) is in IEC 61260 series separated into the three parts covering: specifications, pattern evaluation tests and periodic tests; - the performance category class 0 is removed; - the design goals for the specification can be based only base-10; - the reference environmental conditions have been changed from 20 °C / 65 % RH to 23 °C / 50 % RH; and - IEC 61260 (1995) specified tolerance limits without considering the uncertainty of measurement for verification of the specifications. IEC 61260 series specifies acceptance limits for the observed values and maximum-permitted uncertainty of measurements for laboratories testing conformance to specifications in the standard. LIEC 61260-1:2014 specifie les exigences de performances des filtres passe-bande analogiques, a donnees echantillonnees et numeriques. Letendue de la bande passante de la caracteristique daffaiblissement relatif dun filtre est un pourcentage constant de la frequence mediane exacte pour tous les filtres dune bande passante donnee. Un instrument conforme aux exigences de la presente norme peut contenir nimporte quel nombre de filtres passe-bande adjacents couvrant nimporte quelle gamme de frequences desiree. Les exigences de performances sont fournies pour deux classes de filtres: classe 1 et classe 2. En general, les specifications pour les filtres de classe 1 et de classe 2 disposent des memes objectifs de conception et different principalement dans les limites dacceptation et dans la plage de temperatures dexploitation. Les limites dacceptation de la classe 2 sont superieures ou egales a celles de la classe 1. Les incertitudes de mesure elargies maximales autorisees sont egalement specifiees. Les filtres passe-bande conformes aux exigences de la presente norme peuvent faire partie de differents systemes de mesure ou peuvent etre un composant integre dans un instrument specifique tel quun analyseur de spectre. La presente norme specifie les gammes de conditions denvironnement pour le fonctionnement des filtres. La gamme exigee depend du fait que linstrument contenant les filtres est concu pour fonctionner dans un environnement controle ou plus generalement sur le terrain. Les filtres passe-bande conformes aux exigences de la presente norme sont capables de fournir une information spectrale filtree en bandes de frequences pour une large variete de signaux, comme des signaux variables dans le temps, intermittents ou permanents, a large bande ou composes de frequences discretes, de courtes ou de longues durees. Cette premiere edition de lIEC 61260-1 (2014), la future IEC 61260-2 et la future IEC 61260-3, annulent et remplacent la premiere edition de lIEC 61260 (1995) et son amendement 1 (2001). Cette edition constitue une revision technique qui inclut les modifications techniques majeures suivantes par rapport a lIEC 61260 (1995) et son amendement 1 (2001): - le document unique dans la premiere edition de lIEC 61260 (1995) et son amendement 1 (2001) est, dans la serie IEC 61260 divise selon les trois parties suivantes: specifications, essais devaluation dun modele et essais periodiques; - lIEC 61260-1 (2014) ne contient plus de categorie de performances de classe 0; - dans lIEC 61260-1 (2014), les objectifs de conception de la specification sont bases sur une conception en base 10 uniquement; - les conditions denvironnement de reference sont passees de 20 °C / 65 % dhumidite relative a 23 °C / 50 % dhumidite relative; - lIEC 61260 (1995) et son amendement 1 (2001) specifiait des limites de tolerance sans considerer lincertitude de la mesure pour la verification des specifications. La nouvelle serie IEC 61260 specifie des limites dacceptation pour les valeurs observees et lincertitude maximale autorisee des mesures pour la conformite des essais de laboratoire aux specifications de la norme.
