ETS 300 127-1994
Scope
This European Telecommunication Standard (ETS) specifies the technical requirements for the radiated emission measurement procedure for physically large systems used within the public telecommunication network@ with the exception of radio equipment. It applies to physically large systems which are comprised of equipments 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. The minimum representative system is representative of installed systems in terms of function (which includes at least one of each functional unit type) and electromagnetic radiation characteristics. The minimum representative system is subsequently referred to in this 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].
