Digital radio mondiale (DRM) - Part 2: Digital radio in the bands below 30 MHz - Methods of measurement for DRM transmitters (IEC 62272-2:2007); German version EN 62272-2:2007, text in English
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.
