Foreword

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

This standard supersedes GB/T 12193-1990 "Measuring Method for Mobile Communication FM Radio Receiver".

Compared with GB/T 12193-1990, the main technical changes except editorial modification are as follows.

---Modified the standard name;

--- Increased normative references (see Chapter 2);

--- Modify the DC test voltage (see 4.2.2);

--- Modified the method of measuring the width of the receiving available bandwidth (see 8.2, version 9.1 of 1990);

--- Removed the method of measuring the width of the receiving intermediate frequency (see 9.2 of the 1990 Edition);

--- Removed the modulation receiver bandwidth measurement method (see 9.3 version 8.3);

--- Modify the sensitivity measurement method (see Chapter 7, 1990 version of Chapter 6);

--- Increased measurement methods for the performance of self-contained antenna receivers (see chapters);

--- Added measurement method for receiver expander characteristics (see Chapter 21);

--- Increased receiver output power measurement method (see Chapter 22);

--- Increased measurement methods for receiver spurious components (see Chapter 23);

--- Increased receiver radiation sensitivity measurement method (see Chapter 24);

--- Added a normative appendix "Guide to the use of radio frequency coupled devices" (see Appendix A).

This standard uses the redrafted reference to IEC 60489-3:1999 "Measuring methods for wireless equipment in mobile services Part 3. A3E, the F3E, or G3E Transceiver Receiver, is not equivalent to IEC 60489-3:1999.

3 Terms and Definitions, Abbreviations

3.1 Terms and Definitions

The following terms and definitions apply to this document.

3.1.1

Rated audio output power ratedaudio-frequencyoutputpower(level) the power available at the output specified by the manufacturer when the receiver is connected to the specified load under specified operating conditions.

3.1.2

Reference output power (level) referenceoutputpower(level) the specific value of audio power can be used as a reference level for some measurements.

Note 1. The preferred value of the reference level is. 1mW; 50mW.

Note 2. This level is usually used as the receiver of the electro-acoustic transducer. When measuring the characteristics of the receiver with high output power, the value of this level may be too low.

The test should be performed at or below the rated audio output power.

Note 3. The receiver with no audio output adjustable device has a reference output power equal to the output power value obtained when the receiver inputs a standard test signal.

Note 4. If the output power can only be stepped, the reference output power is taken to be the power closest to the preferred value.

3.1.3

Audio load audio-frequencyload Equipment that has an audio output transducer installed.

Note. The manufacturer shall specify the connection method and give the impedance and tolerance of the transducer at 1000Hz. The upper limit of the specified audio range of the transducer shall also be given.

And lower frequency impedance.

3.1.4

Audio test load audio-frequency testload Instead of the impedance network of the receiver connected to the receiver under normal operating conditions, the network simulates the normal load and any electricity it normally uses.

The impedance of the cable.

Note. This network is specified by the manufacturer and is usually purely resistive.

3.1.5

To aggravate de-emphasis the process of restoring the pre-emphasized transmitted signal back to the original signal.
