Technical specifications and methods of meansurement for MW and SW broadcasting transmitters

BS EN 62272-2:2007 全球数字无线广播(DRM).波段小于30 MHz的数字无线广播.DRM发射机的测量方法

This part of IEC 62272 describes the methods of measurement to assess the performance characteristics of digital modulated radio transmitters in the bands below 30 MHz for sound and/or data broadcasting in the LF, MF and HF bands, and to facilitate 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 radio 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. The measurement methods described in this standard are intended to be used for type approval tests, quality control tests or acceptance test measurements in factories and on site. Fewer or additional measurements may be carried out by agreement between customer and supplier. Any additional test should comply with standards which have been established by other study groups, subcommittees of the IEC or other international or suitably accredited organizations. This standard does not specify limiting values for acceptable performance as these are usually given in the equipment specification or in requirements laid down by the responsible regulation bodies. However, some values are quoted, where appropriate, for guidance in the presentation of the results.

BS EN 62273-1:2007 无线电广播发射机测量方法.地面数字电视发射机的工作特性

This part of IEC 62273 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. No limits have been assigned to quantify acceptable ranges of performance parameters. These are judged to be properly included in the technical specifications for individual transmitters; however, the terms and the manner used to quantify them should ideally be those described in a future IEC publication. The measurement methods described in this standard are intended for type approval tests. However they can equally well apply to acceptance tests measurements and quality control tests either in factories or on site. Test signals are used to measure performance parameters for both digital and analogue terrestrial transmitters. Their electronic characteristics and their associated performance parameters are widely understood. The test signals are measured after they have gone through the transmitter equipment to determine if their degradation is within the required quality criteria. This standard does not go into any detail regarding MPEG 2 signals or DVB processes nor does it deal with digital signal processing.
