SIST EN 62273-1:2007

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

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.

Méthodes de mesure applicables aux émetteurs radioélectriques -- Partie 1: Qualité de fonctionnement 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
