GB/T 16946-2017General specification for shortwave single sideband communication equipments (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 16946-1997 "General Specification for Short-wave Single-sideband Communication Equipment" and GB/T 6933-1995 "Short-wave single-side With transmitter electrical performance measurement methods." This standard is based on GB/T 16946-1997 and incorporates the contents of GB/T 6933-1995.

This standard is compared with GB/T 16946-1997 and GB/T 6933-1995, with the exception of editorial changes, as follows.

--- Modify the voice input level, out-of-band intermodulation and other electrical performance indicators (see 5.8);

--- Increased requirements and test methods for activation time, deactivation time, band conversion time, etc.; reduced adjacent channel power, emission Requirements and test methods for inter-machine intermodulation, pilot drop, etc. (see 5.8 and 6.5);

--- Modify the transmitter part of the measurement method (see 6.5.1).

1 Scope

This standard specifies the terms and definitions, classification, requirements, test methods, inspection rules and signs, packaging, and transport of short-wave single-sideband communication equipment. Transmission and storage requirements.

This standard is applicable to all-solid-state shortwave single-sideband communication equipment for mobile communication or fixed communication on the ground, inland water or at sea (hereinafter referred to as "Communication equipment") includes transmitters, receivers, transceivers (radios) and antenna tuners.
