适用范围： 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 toambiguous interpretation due to the use of different methods and conditions. They are neitherrestrictive nor mandatory: measurements can be chosen for each particular case.The measurement methods described in this standard are intended to be used for typeapproval 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 andsupplier. Any additional test should comply with standards which have been established byother study groups, subcommittees of the IEC or other international or suitably accreditedorganizations.This standard does not specify limiting values for acceptable performance as these areusually given in the equipment specification or in requirements laid down by the responsibleregulation bodies. However, some values are quoted, where appropriate for guidance in thepresentation of the results.
