1 Scope

This standard specifies the definition, measurement conditions, and measurement methods for the performance of mobile communications FM receivers (hereinafter referred to as receivers). This standard applies to the operating frequency of 25MHz ~ 1000MHz, transmission of single-channel voice and other types of signals, the audio bandwidth is not super 10kHz mobile communications FM receiver.

2 Normative references

The following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article Pieces. For undated references, the latest version (including all amendments) applies to this document. GB/T 12192-2017 mobile communication FM transmitter measurement method 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. ......
