    Abstract - (Show below) - (Hide below)

    Gives supplementary terms and definitions and the conditions of measurement for type tests and may be used also for acceptance tests specifically for mobile radio transmitters having audio frequency bandwidths generally not exceeding 10 kHz for the transmission of voice and other types of signals, using single sideband amplitude modulation with full, reduced or suppressed carrier. Includes recommended characteristics of the measuring equipment, guide for construction of a radiation test site (30m) and example of a mains power line stabilization network.
