38、ION RECEIVERS 1 Scope IEC 62028 deals with the standard conditions and methods of measurement on digital television receivers which receive digital television broadcast transmissions. IEC 62028 deals with the determination of performance and allows the comparison of equipment by listing the characte
39、ristics which are useful for specifications and by laying down uniform measuring methods of these characteristics. Performance requirements are not specified, since they are specified by other international, regional or domestic standards for the systems. It does not include the measurements specifi
40、c to the transmission system, such as; measurements on receivers for satellite transmission systems, measurements on receivers for terrestrial transmission systems, measurements on receivers for cable transmission systems, measurements specific to sound channels, and measurements specific to data ch
41、annels. IEC 62028 does not include methods of measurement on outdoor units and antennas for satellite reception, for which reference is required to other appropriate IEC standards. IEC 62028 does not deal with general safety matters, for which reference is required to IEC 60065, or other appropriate
42、 IEC safety standards, nor with radiation and immunity, which will be dealt with by CISPR. 2 Normative references The following referenced documents are indispensable for the application of this document.
