    Abstract - (Show below) - (Hide below)

    General characteristics of broadcast transmitters and standardization of the conditions and methods of measurement to be used to ascertain the performance of a broadcast transmitter and to make the comparison of the results of measurements made by different observers are defined in this Standard. Measurement methods detailed are intended for type tests and may be used for factory and acceptance tests (see clause 3). Does not specify limiting values of the various quantities for acceptable performance, as these should be given in the equipment specification which are relevant, preferable in the form laid down in an appropriate IEC recommendation.
