GB/T 15844-2017General specification for professional radio transceiver employing F3E emission in the mobile services (English PDF)

Foreword

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

This standard replaces GB/T 15844.1-1995 "mobile communication FM radiotelephone general technical conditions", GB/T 15844.2-1995 "Mobile communication FM radiotelephone environmental requirements and test methods" and GB/T 15844.4-1995 "mobile communication FM radiotelephone Machine Quality Assurance Rules. " This standard GB/T 15844.1-1995, GB/T 15844.2-1995 and GB/T 15844.4-1995 revised and integrated into as follows.

--- Standard name "FM radio telephone" to "professional FM transceiver";

--- Added "classification and specifications" (see Chapter 4);

--- Modify the technical requirements for power supply (see 5.1.2 and 5.1.3, GB/T 15844.1-1995 of 5.1.5 and 5.1.9);

--- Modify the continuous launch of various types of professional FM state requirements (see 5.2.3, GB/T 15844.1-1995 of 5.1.11);

--- Transmitter electrical properties, increase the transmitter intermodulation attenuation, transmitting instantaneous frequency characteristics; Modify the carrier frequency tolerance, modulation audio Distortion, modulation characteristics, adjacent channel power (see 5.3, GB/T 15844.1-1995 of 5.2);

--- In the receiver electrical properties, modify the reference sensitivity, squelch sensitivity and squelch adjustment range, audio distortion, audio response, a total of letters Road suppression, blocking, adjacent channel selectivity, spurious response immunity, intermodulation immunity (see 5.4, GB/T 15844.1-1995 5.3);

--- Increased transmitter electrical properties, receiver electrical properties of the definition and measurement methods (see 5.3 and 5.4);

--- Increasing the performance requirements of transponders and their measurement methods (see 5.5 and Appendix A);

--- Modify the environmental test requirements and methods (see Chapter 6, GB/T 15844.1-1995 5.5 and Chapter 6, GB/T 15844.2-1995 Chapter 3, Chapter 4, Chapter 5);

--- Modify the "test rules" (see Chapter 7, GB/T 15844.4-1995 Chapter 4, Chapter 5, Chapter 6);

--- Added "logo, manual" (see Chapter 8);

--- Added product storage related content (see 9.3).

1 Scope

This standard specifies the use of FM (F3E) professional FM transceiver in the mobile communications professional wireless communications system (the following Jane Said the professional FM) classification and specifications, technical requirements, test methods, product inspection rules, as well as signs, instructions, packaging, transportation, Storage, also provides a professional FM analog channel for data transmission technology requirements.

This standard applies to land, inland or coastal mobile communications professionals (wireless) network working frequency is 25MHz ~ 1000MHz, Transmitter RF output power is not more than 50W all kinds of professional FM, FME mobile communications in line with other F3E transceiver can also be reference According to the implementation.
