Sound and television broadcast receivers and
associated equipment - Radio disturbance
characteristics - Limits and methods of measurement
1 Scope
This standard specifies the measurement methods for sound and television
receivers and related equipment, as well as the limits for the control of
harassment from such equipment.
For multifunctional equipment, it shall meet the requirements of this standard
and/or other standards, see 4.1.
This standard is applicable to the electromagnetic energy generated by the
sound of broadcasting and similar transmissions and television receivers and
related equipment; the frequency range is 9 kHz ~ 400 GHz.
Frequencies without specified limits do not need to be measured.
The receiving system used for collective reception, especially the front end of
the cable distribution system (shared antenna TV, CATV) and the shared
receiving system (main antenna TV, MATV) belong to the category of GB 13836.
See Appendix A and Appendix B for the requirements of broadcast receivers for
receiving digital signals.
It does not include information technology equipment (ITE), even if it is
connected to a television receiver.
The telecommunications port connecting the broadcast receiver to the
telecommunications network belongs to the scope of GB 9254.
In addition, when the telecommunication port has a broadcast receiving function,
the broadcast receiving function that can be independent of the
telecommunication function shall be measured separately, meanwhile the
telecommunication function does not work during the measurement.
The PC tuner card shall be measured in accordance with the corresponding
clauses of this standard.
