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).
