Foreword
In order to standardize the open-circuit monitoring of medium and short wave AM broadcasting quality, and to promote the improvement and effective coverage of medium and short wave AM broadcasting quality,
This standard is specially formulated.
Open-circuit monitoring of medium and short wave AM broadcast quality refers to the use of dedicated reception in a specific frequency broadcast service area or a specific reception location.
The device receives airwave signals, performs objective measurement and subjective evaluation of a certain broadcast frequency in real time, and accurately reflects the signal quality,
Radio characteristics and transmitter operating conditions. There are three main types of broadcast quality monitoring projects.
1.Monitoring the quality of broadcast sound
Monitoring of broadcast sound quality includes monitoring of noise, distortion, and amplitude-frequency characteristics. For distortion, amplitude frequency characteristics,
Monitoring of technical indicators such as noise, crosstalk, and alternating sound. This standard mainly refers to GY/T 179-2001 "Operation and Maintenance Regulations for Radio and Television Transmitters."
Appendix F of Cheng "carries out subjective evaluation.
2. Monitoring of broadcast transmission characteristics
The monitoring of broadcast transmission characteristics includes the monitoring of frequency deviation, amplitude modulation, carrier level, and technical specifications of transmission bandwidth.
Refer to GB/T 12572-1990 "Transmitter Frequency Tolerance" and GB/T 12046-1989 "Identification of Radio Transmission and Determination of Necessary Bandwidth"
To monitor.
3.Monitoring of the operating status of broadcast transmitters
The monitoring of the operating status of broadcast transmitters includes monitoring of technical indicators such as out-of-broadcasting (including miscasting, aerial broadcasting, less broadcasting, late broadcasting, and multicasting) and poor broadcasting
For testing, this standard mainly refers to Appendix A of GY/T 179-2001 "Operation and Maintenance Regulations for Radio and Television Transmission Stations" for monitoring.
Appendix A of this standard is an informative appendix.
This standard is under the jurisdiction of the National Radio and Television Standardization Technical Committee.
This standard was drafted. Radio and Television Monitoring Center of the State Administration of Radio, Film and Television.
