適用范圍：This part of IEC 62273 gives the conditions for measuring the performance parameters ofterrestrial digital transmitters and for facilitating the comparison of measurements which arecarried out by different personnel. It contains details of specially selected methods fordetermining the most important performance parameters of digital transmilters Themeasurement methods described apply to a limited number of performance parameters, iethose which can give rise to ambiguous interpretation due to the use of different methods andconditions. They are neither restrictive nor mandatory: measurements can be chosen for eachparticular case. If necessary, additional tests can be carried out but they shall comply withthose standards which have been established by other study groups, subcommittees of theIEC 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 individualtransmitters; however, the terms and the manner used to quantify them should ideally bethose 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 controltests either in factories or on site.Test signals are used to measure performance parameters for both digital and analogueterrestrial transmitters. Their electronic characteristics and their associated performanceparameters are widely understood. The test signals are measured after they have gonethrough the transmitter equipment to determine if their degradation is within the requiredquality criteria.This standard does not go into any detail regarding MPEG 2 signals or DVB processes nordoes it deal with digital signal processing.
