19、L RADIO MONDIALE (DRM) Part 2: Digital radio in the bands below 30 MHz Methods of measurement for DRM transmitters 1 Scope 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
20、 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 measurem
21、ent 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 m
22、ethods 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 st
23、andards 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
24、 down by the responsible regulation bodies. However, some values are quoted, where appropriate, for guidance in the presentation of the results. 2 Normative references The following referenced documents are indispensable for the application of this document.
