This part of IEC 62273 gives the conditions for measuring the performance parameters of
terrestrial digital transmitters and for facilitating 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 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. 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.
The measurement methods described in this standard are intended for type approval tests.
However they can equally well apply to acceptance tests measurements and quality control
tests either in factories or on site.
Test signals are used to measure performance parameters for both digital and analogue
terrestrial transmitters. Their electronic characteristics and their associated performance
parameters are widely understood. The test signals are measured after they have gone
through the transmitter equipment to determine if their degradation is within the required
quality criteria.
This standard does not go into any detail regarding MPEG 2 signals or DVB processes nor
does it deal with digital signal processing.
