GB 13837-2012 Sound and television broadcast receivers and associated equipment—Radio disturbance characteristics—Limits and methods of measurement (English Version)
1 Scope
This standard specifies the methods of measurement applicable to sound and television receivers or associated equipment and specifies limits for the control of disturbance from such equipment.
For multifunction equipment which is subjected simultaneously to different clauses of this standard and/or other standards, details are given in 4.1.
This standard applies to the generation of electromagnetic energy from sound and television receivers for the reception of broadcast and similar transmissions and from associated equipment. The frequency range covered extends from 9 kHz to 400 GHz.
No measurements need be performed at frequencies where no limits are specified.
Receiving systems for collective reception, in particular cable distribution head ends (Community Antenna Television, CATV) and community reception systems (Master Antenna Television, MATV) are covered by GB 13836.
Broadcast receivers for digital signals are covered by Annex A and Annex B.
Information technology equipment (ITE) is excluded, even if intended to be connected to a television broadcast receiver.
The telecommunication port of broadcast receivers, intended to be connected to a telecommunication network, is covered by GB 5294.
In addition, measurements at the telecommunication port are performed with the broadcast reception functions, which are independent from the telecommunication function, disabled during the measurement.
PC tuner cards are measured according to the relevant clauses of this standard.
