What is BS EN 62272-2- Digital Radio Mondiale (DRM) about?
BS EN 62272-2 describes the methods of measurement to assess the performance characteristics of the 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.
BS EN 62272-2 contains details of specially selected methods for determining the most important performance parameters of digital radio transmitters. The measurement methods described applying 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 case.
Note 1: BS EN 62272-2 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 regulatory bodies. However, some values are quoted, where appropriate, for guidance in the presentation of the results.
Note 2: Feeders and antennas to which the transmitter might be connected are not considered part of the transmitter and therefore excluded.
Who is BS EN 62272-2- Digital Radio Mondiale (DRM) for?
BS EN 62272-2 on Digital Radio Mondiale (DRM) is relevant to:
- Manufacturers of DRM transmitters
- Manufacturers of Digital Radio Mondiale receiver
- Test providers of DRM transmitters
- Digital radio broadcasting personnel
- Regulatory authorities
Why should you use BS EN 62272-2- Digital Radio Mondiale (DRM)?
Digital Radio Mondiale (DRM) is a set of techniques regarding digital audio broadcasting, composed to work over the bands used for radio broadcastings. DRM transmitters are the sound broadcasting transmitters operating in bands below 30 MHz and incorporating digital modulation.
BS EN 62272-2 presents you with the methods of measurements for DRM transmitters digital radio Mondiale with the necessary bandwidth for a DRM signal considered the same as the allocated channel bandwidth, for example, 10 kHz for a standard HF channel.
BS EN 62272-2 describes the measurement methods that help the users 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 end-user and supplier.
Overall, BS EN 62272-2 is useful as it provides guidance on the bands below 30 MHz and its methods of measurement for DRM transmitters, which can be helpful for your business.
