Foreword
This second edition European Telecommunication Standard (ETS) has been produced by the EMC and
Radio Spectrum Matters (ERM) Technical Committee of the European Telecommunications Standards
Institute (ETSI).
This ETS has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 83/189/EEC (as amended) laying down a procedure for the provision of
information in the field of technical standards and regulations.
This ETS, together with ETS 300 682, is intended to become a Harmonized Standard, the reference of
which will be published in the Official Journal of the European Communities referencing the Council
Directive on the approximation of the laws of the Member States relating to electromagnetic compatibility
("the EMC Directive") (89/336/EEC as amended).
Annex A provides requirements concerning test sites and general arrangements for measurements
involving the use of radiated fields.
Annex B provides requirements concerning measuring support for pocket equipment.
Annex C contains specifications for the adjacent channel power measuring receiver.
Annex D is a graphical representation of subclause 10.4.1.3 referring to the limits for spurious radiation
from loop receivers.
Annex E contains technical specifications relevant to the EMC Directive.
Annex F contains the ERC Decision which references the technical specifications in this ETS for inclusion
in national type approval regulations.
Annex G provides information concerning the on-site paging service.
Annex H contains a bibliography.
This ETS also contains text concerning type approval of the equipment to which it relates. This text should be
considered only as guidance and does not make this ETS mandatory in its status as a standard. However,
this ETS can be referenced, wholly or in part, for mandatory application by decisions of regulatory bodies.
This ETS is based mainly on CEPT Recommendation T/R 20-05 and ESPA publications 4.2.6 and 4.2.6.a.
