GB/T 9383-2008 Sound and television broadcast receivers and associated equipment—Immunity characteristics—Limits and methods of measurement

Scope

This standard applies to sound and television broadcast receivers and related equipment used in residential, commercial, and light industrial environments. This standard specifies the immunity limits and measurement methods for radio interference signals for sound and television receivers and related equipment. This standard also applies to the immunity of direct-to-home (DTH) outdoor units of individual reception satellite systems. Note 1: For collective reception systems, especially front-end equipment of cable distribution systems (CATV) and shared reception system equipment (MATV), see GB 13836. Note 2: Requirements for digital signal broadcast receivers are specified in Appendix H. The frequency range of this standard is 0 Hz to 400 GHz, and there are no requirements for RF testing or related phenomena outside this frequency range. The purpose of this standard is to specify the immunity test requirements for the above-mentioned equipment against continuous or transient conducted and radiated interference, as well as against electrostatic discharge. These test requirements represent basic electromagnetic immunity requirements. These test requirements should consider each port (including the shell and connection ends). Note 3: This standard does not address the electrical safety requirements of equipment, such as protection against electric shock, unsafe operation, insulation coordination, and related insulation tests. Note 4: In some cases, the interference level may exceed the levels specified in this standard, for example, when a handheld transmitter is close to the equipment under test. In this case, it may be necessary to use special mitigation measures to reduce the environmental level. The environments applicable to this standard include residential, commercial, and light industrial areas, both indoors and outdoors. The following places are given as representatives of these environments: - Residential areas, such as residences, apartments, etc.; - Retail o
