44、 Upper Side Band 4 General 4.1 Presentation of equipment for testing purposes Each equipment to be tested shall fulfil the requirements 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 opera
45、ting conditions and power requirements as applicable, to establish the appropriate test conditions. ETSI ETSI EN 300 433-1 V1.3.1 (2011-07) 10The equipment shall be tested to the present document using the type of modulation signal defined in clause 6.5 that is relevant to the operational mode being
46、 tested, i.e. angle modulation, DSB or SSB. Angle modulation is considered as equivalent to frequency modulation (FM) with pre-emphasis in transmit mode and de-emphasis in receive mode. Equipment capable of using two or three types of modulation among angle modulation, DSB and SSB shall be tested to
47、 the present document using the respective type of modulation for each mode (see clause 6.5). Additionally, technical 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
48、of the equipment, as appropriate for testing. Stand alone equipment shall be complete with any ancillary equipment needed for testing. If an equipment has several optional features, considered not to affect the RF parameters then the tests to be performed on the equipment configured with that combin
49、ation of features considered to be the most complex. Where practicable, equipment to be tested shall provide 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 a second sample of the equipment shall be supplied with a temporary antenna connector fitted to facilitate testing. The performance of the equipment to be tested shall be representative of the performance of the corresponding production model. If type approval is giv
