Frequency range of out-of-band emissions

Radiated broadband and narrowband electromagnetic emissions from electronic sub-assemblies

Radiated broadband and narrowband electromagnetic emissions from vehicles

In order to ensure that radio equipment uses the radio spectrum effectively and supports the efficient use of radio spectrum, radio equipment should be constructed so that: in the case of a transmitter, when the transmitter is properly installed, maintained and used for its intended purpose it generates radio waves emissions that do not create harmful interference, while unwanted radio waves emissions generated by the transmitter (e.g. in adjacent channels) with a potential negative impact on the goals of radio spectrum policy should be limited to such a level that, according to the state of the art, harmful interference is avoided; and ...[+++], in the case of a receiver, it has a level of performance that allows it to operate as intended and protects it against the risk of harmful interference, in particular from shared or adjacent channels, and, in so doing, supports improvements in the efficient use of shared or adjacent channels.

4.2.4. Where, as defined according to Section 6 in conjunction with Annex II, Appendix 2, one engine family covers more than one power band, the emission values of the parent engine (type approval) and of all engine types within the same family (COP) must meet the more stringent requirements of the higher power band.

6.3.1. If the conformity of a vehicle, component or STU taken from the series is being verified, production will be deemed to conform to the requirements of this Directive in relation to broadband radiated emissions and narrowband radiated emissions if the levels measured do not exceed by more than 2db (25 %) the reference limits prescribed in 5.2.2.1, 5.2.2.2, 5.3.2.1 and 5.3.2.2 (as appropriate).
