This standard specifies the electrical performance measurement conditions, definitions and measurement methods of short-wave single sideband transmitters (referred to as transmitters). This standard applies to transmitting equipment without a complete antenna, whose audio bandwidth does not exceed 10kHz full carrier (H3E), reduced carrier (R3E) and suppressed carrier (J3E), including shortwave single-sided independent sideband (B8E) with transmitter. It is also suitable for short-wave single-sideband transmitters compatible with double-sideband AM (A3E) and constant-amplitude (A1A, A1B). This standard only provides the measurement methods of electrical properties and the relevant conditions. The measurement items and performance indicators are in accordance with the provisions of the equipment specification. For special transmitters, the definitions and measurement methods of electrical performance items not specified in this standard shall be stipulated by both parties through negotiation.
