This standard refers specifically to 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.
This standard is intended to be used in conjunction with IEC Publication 489-1: Part 1: General Definitions and Standard Conditions of Measurement. The supplementary terms and definitions and the conditions of measurement set forth in this standard are intended for type tests and may be used also for acceptance tests.
