描述了用于评估发射机性能的条件和测量方法，包括想要的和不想要的调制。所述的测量方法仅限于那些由于使用不同的测量方法和条件而容易产生歧义的特性，这些特性用于型式试验和验收试验，但也可用于工厂试验。

Describes the conditions and methods of measurement for assessing the performance of transmitters with respect to wanted and unwanted modulation. The methods of measurement described are restricted to those properties that may be liable to ambiguous interpretation due to the application of different methods and conditions of measurement and are intended for type tests and acceptance tests but may also be used for factory tests.
