41、equirements of the present document on all frequencies over which it is intended to operate. The provider or manufacturer shall declare the frequency ranges, the range of operating conditions and power requirements as applicable, to establish the appropriate test conditions. Additionally, technical
42、documentation and operating manuals, sufficient to make the test, shall be supplied. 4.1.1 Choice of model for testing The provider or manufacturer shall provide one or more samples of the equipment, as appropriate for testing. Stand alone equipment shall be complete with any ancillary equipment nee
43、ded for testing. If an equipment has several optional features, considered not to affect the RF parameters then the tests need only to be performed on the equipment configured with that combination of features considered to be the most complex. Where practicable, equipment to be tested shall provide
44、 a 50 connector for conducted RF power level measurements. In the case of integral antenna equipment, if the equipment does not have an internal permanent 50 connector then it is permissible to supply a second sample of the equipment with a temporary antenna connector fitted to facilitate testing. E
45、TSI ETSI EN 300 135-1 V1.2.1 (2008-02) 10The performance of the equipment to be tested shall be representative of the performance of the corresponding production model. Tests shall be carried out on the highest and lowest channel within the switching range of the equipment and on a channel near the
46、middle of the switching range. The switching range of the receiver and transmitter shall be declared by the manufacturer. The switching range is the maximum frequency range over which the receiver or the transmitter can be operated without reprogramming or realignment. In the case of equipment fitte
47、d with one channel only, all tests are carried out on that channel. In the case of equipment fitted with two channels, all tests are carried out on both channels. 4.1.1.1 Auxiliary test equipment Setting up instructions and other product information shall accompany the equipment to be tested. 4.1.1.
48、2 Declarations by the provider The provider or manufacturer shall declare the necessary information of the equipment with respect to all technical requirements set by the present document. In the case of hand portable equipment without a 50 external antenna connector, see clause 4.2. 4.2 Testing of
49、equipment that does not have an external 50 RF connector (integral antenna equipment) Where equipment has an internal 50 connector it shall be permitted to perform the tests at this connector. Equipment may also have a temporary internal 50 connector installed for the purposes of testing. No connection shall be made to any internal permanent or temporary antenna connector during the performance of radiated emissions measurements, unless such action forms an essential part of the normal intended operation of the equipment, as declared by the manufac
