scope:

The object of this Recommendation is to standardize the conditions and methods of measurement to be used to ascertain the performance of a radio transmitter and to make possible the comparison of the results of measurements made by different observers. This Recommendation contains details of selected methods of making measurements, recommended for assessing the essential properties of a radio transmitter. The methods of measurement describe are restricted to those properties that may be liable to ambiguous interpretation due to the application of different methods and conditions of measurement. They are neither mandatory nor limiting; a choice of measurements can be made in each particular case. If necessary, additional measurements may be performed, but these shall preferably be carried out in accordance with the standards as laid down by the standardizing body of the country concerned. Limiting values of the various quantities for acceptable performance are not specified as these should be given in the relevant equipment specification. The methods of measurement detailed in this Recommendation are intended for type tests and may also be used for acceptance tests and factory tests. The standard conditions of measurement and (unless otherwise specified in the other parts) the methods of measuring the characteristics given in this part of the Recommendation, apply to radio transmitters for various classes of emission.
