GB/T 13837-2012 Sound and television broadcast receivers and associated equipment—Radio disturbance characteristics—Limits and methods of measurement
Basic Information
Scope
This standard specifies the measurement methods for audio and television receivers and related equipment, and also stipulates the limits for controlling the interference of such equipment.
For multifunctional devices, the requirements of this standard and/or other relevant provisions of other standards should be met simultaneously, see 4.1.
This standard applies to the electromagnetic energy generated by audio and television receivers and related equipment that receive broadcasts and similar transmissions, with a frequency range of 9 kHz to 400 GHz.
The frequencies for which no limits are specified do not need to be measured.
Receiving systems used for collective reception, especially the front-ends of cable distribution systems (community antenna television, CATV) and shared receiving systems (master antenna television, MATV), fall within the scope of GB 13836.
The requirements for broadcast receivers used to receive digital signals are described in Appendices A and B.
Information technology equipment (ITE) is not included, even if it is connected to a television receiver.
The telecommunications ports of broadcast receivers connected to telecommunications networks fall within the scope of GB 9254.
In addition, when the telecommunications port has a broadcast receiving function, the broadcast receiving function independent of the telecommunications function should be measured separately, and the telecommunications function should not be in operation during the measurement.
PC tuning cards should be measured in accordance with the corresponding provisions of this standard.
