31、andard has been prepared by the Radio Equipment and Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI). me draft has undergone the ETSI public enquiry process, and is now published. The standard which is based upon CEPT Recommendation T/R 24-01, is a gene
32、ral standard which may be superseded by specific standards covering specific applications. Angle modulation is used for radio equipment covered by this ETS, but individual national administrations are free to choose the type of modulation. Channel separations, maximum transmitter output power / effe
33、ctive radiated power, class of transmitter intermodulation attenuation and the inclusion of automatic transmitter shut-off facility may all be conditions relating to the issue of a licence by the appropriate administration. P Additional standards or specifications may be required for equipment such
34、as that intended for connection to the public switched telephone network (PSTN). This standard does not cover requirements for radiated emissions below 30 MHz. It is anticipated that methods of measurements and minimum standards for such emissions will be covered by specifications supporting EMC Dir
35、ective 891336 EEC. Annex A provides additional information concerning radiated measurements. Annex B contains normative specifications for adjacent channel power measurement arrangements. Annex C is a graphic representation of the normative subclause 3.1, referring to the presentation of equipment f
36、or testing purposes. Introduction This standard is intended to specify the minimum performance and the methods of measurement of radio equipment for use in the land mobile service as specified in the Scope. Clause 4 provides the corresponding limits. These limits have been chosen to ensure an accept
37、able grade of service and to minimise harmful interference to other equipment and services. They are based on the interpretation of the measurement results described in SubClaus8 3.3. This standard will also be used by accredited test laboratories for the assessment of the performance of the equipme
38、nt. The performance of the equipment submitted for type testing shall be representative for the performance of the Corresponding production model. In order to avoid any ambiguity in that assessment, this standard contains instructions for the presentation of equipment for type testing purposes (clau
39、se 3), conditions (clause 5) and measurement methods (clauses 7 and 8). This standard was drafted on the assumption that: - the type test measurements will be performed oniy once, in one of the accredited test laboratories, and the measurements accepted by the various authorities in order to grant t
40、ype approval, if equipment available on the market is required to be checked it shall be tested in accordance with the methods of measurement specified in this standard. Page 8 ETS 300 086:1991 This standard covers base stations, mobile stations and two categories of hand portable stations. One cate
41、gory is fitted with a 50 n external antenna socket or connector. The other category has no external antenna socket, but: - either it is fitted with a permanent internal 50 n RF connector, - or it can be fitted with a temporary internal 50 RF connector,so that conducted measurements can be performed.
42、 The means to access andior implement the internai connector shall be provided by the manufacturer. Details of the means used during type testing shall be provided by the accredited test laboratory with the test report, subclause 3.1.12. Peg. 9 ETS 300 086:1997 1 Scope This standard covers the minim
43、um characteristics considered necessary in order to make the best use of 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 angle modulation systems fo
44、r use in the land mobile service, operating on radio frequencies between 30 MHz and 1000 MHz, with channel separations of 12.5 kHz. 20 kHz and 25 kHz, and intended primarily for analogue speech. In this standard different requirements are given for the different radio frequency banda, channel separa
45、tions, environment+ conditions and types of equipment, where appropriate. The types of equipment covered by this standard are as follows: - Base station: equipment fitted with an antenna socket. - Mobile station: equipment fitted with an antenna socket. - Handportable stations: a) fitted with an ant
46、enna socket, b) without an external antenna socket (integral antenna equipment) but fitted with a permanent internal or a temporary internal 50 fi R.F. connector which allows access to the transmitter output and the receiver input. For the type of equipment defined in (b) the additional measurements
47、 which shall be made using the equipment antenna connected to the station (and not using any connector) are as follows: - Transmitter effective radiated power - Transmitter radiated spurious emissions - Receiver maximum usable sensitivity (field strength) - Receiver radiated spurious emissions Handp
48、ortable equipment without an external or internal RF connector and without the possibility of having a temporary internai 50 R RF connector is not covered by this standard. 2 Definitions, abbreviations and symbols 2.1 Definitlons For the purpose of this standard. the following definitions appy: Baso
49、 statlon: equipment fitted with an antenna socket, for use with an external antenna, and intended for use in a fixed location. Mobilo station: mobile equipment fitted with an antenna socket, for use with an external antenna, normally used in a vehicle or as a transportable station. Handportablo station: equipment either fitted with an antenna socket or an integral antenna. or both, normally used on a stand-alone basis, to be carried on a person or held in the hand.
