scope:

This 2nd draft European Telecommunication Standard (ETS) specifies the technical requirements for the radiated emission measurement procedure for physically large systems used in telecommunications.

It applies to physically large systems which are comprised of equipment (or systems) requiring installation documentation specific for those sites at which they are to be installed. In order to demonstrate compliance of such systems, a minimum representative system is defined, which is used for compliance testing. Installations built from units of the complying minimum representative system are deemed to satisfy the radiated emission requirements.

A minimum representative system is one which includes at least one of each type of sub-systems which are connected together to form an installed system. Therefore, the sub-systems, so connected together, are the minimum configurable representative system. These form the requirement for a minimum representative system, subsequently referred in the ETS as the Equipment Under Test (EUT), to be used for compliance testing.

Minimum representative systems shall be tested on an Open Area Test Site (OATS) or in a suitable chamber, the limits to be used are those as specified in EN 55022 [1].
