Radio Equipment and Systems (RES); Electro-Magnetic Compatibility (EMC) Standard for Wireless Microphones and Similar Radio Frequency (RF) Audio Link Equipment
This ETS covers the assessment of radio communication and ancillary equipment in respect of electromagnetic compatibility. Technical specifications related to the antenna port are not included in this standard. Such technical specifications are found in the relevant product standards for the effective use of the radio spectrum. This ETS specifies the applicable EMC tests@ the measurement methods@ the limits and the minimum performance criteria for wireless microphones and similar RF audio link equipment operating in the frequency range 25 MHz to 4 GHz@ and any associated ancillary equipment. The environment classification used in this ETS refers to the environment classification used in the Generic Standards EN 50081-1 [2]@ EN 50082-1 [3]@ except the vehicular environment class which refers to ISO 7637 [4]. The EMC technical specifications have been selected to ensure an adequate level of compatibility for apparatus at residential@ commercial@ light industrial and vehicular environments. The levels however do not cover extreme cases which may occur in any location but with a low probability of occurrence. This ETS may not cover those cases where a potential source of interference@ which is producing individually repeated transient phenomena or a continuous phenomena@ is permanently present@ e.g. a radar or broadcast site in the near vicinity. In such a case it may be necessary to use special mitigation measures applied to either the source of the interference or to the interfered part of both. If other transmitters or receivers are combined with either wireless radio microphones or RF audio link equipment@ they shall be tested to their appropriate EMC standard. Compliance of radio equipment to the technical specifications of this ETS does not signify compliance to any requirements related to the use of the equipment (licensing requirements). Compliance to this ETS does not signify compliance to any safety requirement. However@ it is the responsibility of the assessor of the equipment that an observation regarding the equipment becoming dangerous or unsafe as a result of the application of the tests defined in this ETS should be recorded in the test report.
