scope:
This European Telecommunication Standard (ETS) specifies the technical requirements for the radiated emission measurement procedure for physically large systems used in telecommunication.
It applies to application specific systems, which are equipment or systems requiring installation documentation specific for the site at which the system is to be installed. That is, the system is unique to that particular site. In order to demonstrate compliance of such unique systems, a minimum representative sub-set of the system is defined which is used for compliance testing. Installations built from sub-units of the representative system are deemed to satisfy the requirements for certification.
The test method, where applicable, and limits to be used, are those as specified in EN 55022 [1]. Minimum representative systems shall be tested on a free field site or in a suitable anechoic chamber which has a site attenuation according to the requirements of CISPR Publication 16 [2].
A minimum representative system is one which includes at least one of each type of sub-system, connected together to form an installed system. Thus the sub-systems so connected together are the minimum configurable representative system. These form the requirement for a minimum representative system, subsequently referred to in this document as the Equipment Under Test (EUT), to be used for compliance testing.
