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

--- Modify the transmitter part of the measurement method (see 6.5.1). Please note that some of the contents of this document may involve patents.

1 Scope

GB/T 16946-2017 is the Chinese national standard on general specification for shortwave single sideband communication equipments, in the field of telecommunications and audio-video engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 29 December 2017 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 July 2018. Classification: ICS 33.060.01, CCS M36. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

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.
