This Interim European Telecommunication Standard (I-EIS) has been prepared by the Radio Equipment and Systems (RES) Technical Committee of the Europe
28、an Telecommunications Standards Institute (ETSI) and having passed through ETSI standards approval procedure, is now published. This is a general standard based upon CEPT Recommendations T/R 20-03 ill and T/R 20-04 21. Antenna type/connector I nteg rat Integral External socket External socket All ty
29、pes of modulation for radio devices, except Code Division Multiple Access (CDMA), are covered by this I-ETS. For regulatory purposes the equipment is divided into four main classes based on frequency range and maximum output power (see table 11, and further divided into classes based on the use insi
30、de or outside the Industrial Scientific and Medical (ISM) bands and on the use of the antenna (see table 2). Table 1 Table 2 The CEPT Recommendation T/R 01-04 161 covering Low Power Devices (LPD) is supported by class I.a., from the above tables, see Annex A, Clause A.l. For non-harmonised parameter
31、s, national administrations may impose conditions on the type of modulation, channel/frequency separations, maximum transmitter output power/effective radiated power, equipment marking and the inclusion of an automatic transmitter chut-off facility as a condition of the issue of an individual or gen
32、eral licence, or, as a condition of use under licence exemption. The extreme temperature ranges are fixed and are given in subclause 5.4.1.2. This I-ETS does not cover requirements for radiated emissions below 25 MHz. Additional standards or specifications may be required for equipment such as that
33、intended for connection to the Public Switched Telephone Network (PSTN). ETSI I-ETS*300 220 93 3400855 00287b0 764 H Page 8 I-ETS 300 2201993 Introduction This I-ETS is intended to specify the minimum performance and the methods of measurement for short range devices as specified in the scope. When
34、ETSI publishes a standard covering a specific application for short range devices, it will supersede this general standard. Interference from other services and systems has not been taken into account in this I-ETS. Included are methods of measurement for equipments fitted with antenna sockets and/o
35、r integral antenna. Equipment designed for use with an integral antenna may be supplied with a temporary externaMnterna1 or permanent internal 50 ohm connector for the purpose of testing, providing, the characteristics being measured are not expected to be affected. The performance of the equipment
36、submitted for type testing should be representative of the performance of the corresponding production model. In order to avoid any ambiguity in that assessment, this LETS contains instructions for the presentation of equipment for type testing purposes (see subclause 4.1 1, conditions of testing (s
37、ee Clause 5). This I-ETS was drafted on the assumption that: “Type test measurements, performed in an accredited test laboratory, shall be accepted by the various National Regulatory Authorities in order to grant type approval, provided the National regulatory requirements are met. In addition natio
38、nal administrations may accept a “certificate of conformity“ based on the type test report“. This is in compliance with CEPT Recommendation T/R 71 -03 171. Clauses 1 and 3 provide a general description on the types of equipment covered by this I-ETS and the definitions and abbreviations used. Clause
39、 4 provides a guide as to the number of samples required in- order that type tests may be carried out, and any markings on the equipment which the applicant should provide. Clauses 7 and 8 provide the limits of the parameters which are required to be tested. These limits have been chosen to minimise
40、 harmful interference to other equipment and services. It also provides details on how the equipment should be tested and the conditions which should be applied. Clause 9 gives the maximum measurement uncertainty values. Annex A provides information on specific applications covered by this I-ETS. An
41、nex B provides specifications concerning radiated measurements. Annex C contains specifications for adjacent channel power measurement arrangements. Annex D is a graphic representation of subclause 4.1, referring to the presentation of equipment for testing purposes. Annex E provides information on
42、the correction curve to be used for pulsed systems. Annex F provides information on the spectrum analyser specification. ETSI I-ETSP300 220 93 I 3400855 0028763 hTO M Page 9 I-ETS 300 220:1993 1 Scope This I-ETS covers the minimum characteristics considered necessary in order to make the best use of
43、 the available frequencies. It does not necessarily include all the characteristics which may be required by a user, nor does it necessarily represent the optimum performance achievable. It applies to short range devices: - with an antenna connection and/or with an integral antenna; - for alarms, te
44、lecommand, telemetry, etc., applications; - with or without speech; - operating on radio frequencies between 25 MHz and 1 O00 MHz, with power levels up to 500 mW, radiated or terminated. This LETS covers fixed stations, mobile stations and portable stations. It applies also to Low Power Devices (LPD
45、), as defined in the CEPT Recommendation T/R O1 -04 61. In this LETS basic requirements are given for the different frequency bands, channel separation etc., where appropriate. 2 Normative references This I-ETS incorporates by dated or undated reference, provisions from other publications. These nor
46、mative references are cited at the appropriate places in the text and the publications listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this I-ETS only when incorporated in it by amendment or revision. For undated references the late
