IEC 62273-1:2007

Methods of measurement for radio transmitters - Part 1: Performance characteristics of terrestrial digital television transmitters

IEC 62273-1:2007 gives the conditions for measuring the performance parameters of terrestrial digital transmitters and for facilitating the comparison of measurements which are carried out by different personnel. It contains details of specially selected methods for determining the most important performance parameters of digital transmitters. The measurement methods described apply to a limited number of performance parameters, i.e. those which can give rise to ambiguous interpretation due to the use of different methods and conditions. They are neither restrictive nor mandatory: measurements can be chosen for each particular case. If necessary, additional tests can be carried out but they shall comply with those standards which have been established by other study groups, subcommittees of the IEC or other international or suitably accredited organizations. This bilingual version (2012-03) corresponds to the monolingual English version, published in 2007-02.

Méthodes de mesure applicables aux émetteurs radioélectriques - Partie 1: Caractéristique de performance des émetteurs de télévision numérique terrestre

La CEI 62273-1:2007 définit les conditions permettant de mesurer les performances des émetteurs numériques terrestres et de faciliter la comparaison de mesures réalisées par différentes personnes. Elle détaille des méthodes plus particulièrement choisies pour déterminer les caractéristiques de performance principales des émetteurs numériques. Les méthodes de mesure décrites s'appliquent à un nombre limité de caractéristiques, comme par exemple, celles qui donneraient lieu à une interprétation ambiguë de par l'utilisation de différentes méthodes et conditions de mise en application. Elles ne sont ni restrictives, ni obligatoires: il est permis de choisir la méthode d'évaluation en fonction du cas se présentant. Il est envisageable de compléter les essais réalisés; dans ce cas, ils doivent respecter les normes établies par d'autres groupes d'étude, par des sous-comités de la CEI ou d'autres organismes internationaux ou accrédités. La présente version bilingue (2012-03) correspond à la version anglaise monolingue publiée en 2007-02.

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.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
