Description:This standard specifies the measurement method of sound and television receiver and related equipment, at the same time also stipulates the control harassment limit of such devices. For multi-function equipment should meet this standard at the same time and/or other relevant provisions of standard requirement, see 4.1.
this standard applies to receive radio and similar transmission of sound and television receiver and related equipment of electromagnetic energy, frequency range 9 KHZ ~ 400 GHZ. There is no limit, the frequency of don't need to come in Line measurement.
to collective receive the receiving system, especially in the cable distribution system front-end (community antenna television, CATV) and sharing of the receiving system (main
TV antenna, MATV) belongs to the category of GB13836.
used to receive digital radio receiver is asking to see annex A and annex B.
don't include information technology equipment (ITE), even if it is connected to a television receiver.
radio receiver connected to the telecom network telecommunication port, belongs to the scope of the GB9254.
in addition, when the telecommunication port has a radio receiver function, can be independent of the functions of telecommunications radio receiving should be measured separately, telecommunications functions don't work during the measurement.
PC tuner card should according to the relevant provisions of this international standard to measure.
