The relevant MS and BS

38、transmit bands, as defined in EN 300 392-2 2. 5.2 Manufacturers declarations The manufacturer shall declare: a) The operating band or bands of the repeater. b) The maximum rated output power per channel. c) The number of channels supported by the repeater. 5.3 Test system The test system shall confo

39、rm to the requirements of EN 300 394-1 1, annex B. 5.4 Test environments For each test in the present document, the environmental conditions under which the repeater is to be tested are defined in EN 300 394-1 1, clause 6. 5.5 Repeater test specification 5.5.1 Spurious emissions and Wideband noise 5

40、.5.1.1 Test purpose The purpose of this test is to establish the level of conducted spurious emissions and wideband noise (see clause 3.1) at the antenna ports and the effective power of spurious emissions radiated by the cabinet and structure. 5.5.1.2 Test case The repeater shall be set to maximum

41、gain. All measurement steps, as described in this clause, apply to all antenna ports of the repeater. a) Spurious emissions from the antenna port: one antenna port of the repeater shall be connected to a selective RF measurement device presenting to the repeater a load with an impedance of 50 . An a

42、verage power measurement of spurious emissions shall be performed for frequency offsets from the carrier frequency greater than 600 kHz under the following two conditions: i) Without any RF input signal. The relevant input antenna port of the repeater shall be terminated with 50 . ii) With a RF inpu

43、t signal. The relevant antenna input port of the repeater shall be connected to a RF signal generator. A continuous sinusoidal RF signal shall be fed to the input of the repeater and increased, until the maximum rated output power per channel, as declared by the manufacturer, is reached. The RF inpu

44、t signal shall be set to the centre frequency of the repeaters operating band. In the case of a channelized repeater, the RF input signal shall be set to the centre of the supported TETRA channel closest to the centre of the range of the channels supported by the repeater. ETSI ETSI TS 101 789-1 V1.

45、1.2 (2007-04) 9 b) Wideband noise: one antenna port of the repeater shall be connected to a selective RF measurement device presenting to the repeater a load with an impedance of 50 . A measurement of wideband noise shall be conducted in accordance with the offsets defined in table 4. The measuremen

46、t shall be conducted under the conditions outlined in clause 5.5.1.2 item a), parts i) and ii), of the present document. c) Radiated spurious emissions: a test site fulfilling the requirements of EN 300 113-1 3 shall be used, except when it conflicts with the present document. The repeater shall be

47、placed on a non-conducting support and shall be operated from a power source as recommended by the manufacturer via an RF filter, to prevent the power source or cable from influencing the result of the measurement. The relevant output antenna port of the repeater shall be terminated with 50 . The re

48、levant antenna input port of the repeater shall be connected to a RF signal generator in such a way that the connection does not influence the result of the measurement. The RF input signal shall be set to the centre frequency of the repeaters operating band. A continuous sinusoidal RF signal shall

49、be input at a level, which will result in the maximum rated output power per channel, as declared by the manufacturer. The output level shall be confirmed by measurement. An average RF power measurement shall be performed for frequency offsets from the carrier frequency greater than 600 kHz over the frequency range 30 MHz to 4 GHz. The repeater shall be rotated through 360 in the horizontal plane and the test antenna shall be raised or lowered until the maximum spurious signal level is detected.
