BS EN 62273-1 gives the conditions for measuring the performance parameters of terrestrial digital transmitters and for facilitating the comparison of measurements that are carried out by different personnel.
BS EN 62273-1 contains details of specially selected methods for determining the most important performance parameters of digital 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. 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.
Note: BS EN 62273-1 does not go into any detail regarding MPEG 2 signals or DVB processes, nor does it deal with digital signal processing.
BS EN 62273-1 on terrestrial digital television transmitters is relevant to:
Terrestrial digital television facilitates better audio-video quality multiple channels through a single transmitter.
BS EN 62273-1 provides you with the test methods for measuring the performance characteristics of the terrestrial digital television transmitters. It describes the measurement methods that are helpful to the users for type approval tests.
BS EN 62273-1 is also used for the acceptance tests measurements and quality control tests either in factories or on-site. BS EN 62273-1 gives you test signals that help the users to measure performance parameters for both digital and analogue terrestrial transmitters.
Adopting BS EN 62273-1 results in understanding the electronic characteristics and associated performance parameters of terrestrial transmitters. The test signals are measured after they have gone through the transmitter equipment to determine if their degradation is within the required quality criteria.
Overall, BS EN 62273-1 is useful as it provides guidance on the methods of measurement for radio transmitters and the performance characteristics of terrestrial digital television transmitters, which can be helpful for your business.
