ETSI ETSI EN 303 372-2 V1.1.1 (2016-04) 5 1 Scope The present document applies to indoor units (IDUs) for satellite broadcast reception
22、. An indoor unit gets on an input interface the signal that has been received from satellite and processed by the outdoor unit (ODU). It performs carrier selection, demodulation, audio and video decoding. Part of the IDU functionality may be integrated with the ODU. In that case the present document
23、 applies to this part of functionality as well as the remaining part in the IDU. The indoor unit may be integrated with a domestic television receiver. The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the efficient use of radio spectru
24、m in order to avoid harmful interference. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

34、uirements specifications 4.1 Environmental profile The technical requirements of the present document apply under the environmental profile for operation of the equipment, which shall be declared by the supplier. The equipment shall comply with all the technical requirements of the present document
35、at all times when operating within the boundary limits of the declared operational environmental profile. 4.2 Equipment capabilities The technical requirements of the present document apply under the capabilities of the equipment, which shall be declared by the supplier. The equipment shall comply w
36、ith all the technical requirements of the present document at all times when operating within the boundary limits of the declared equipment capabilities. Equipment capabilities comprise the following characteristics: Input frequency band Input level range Modulation and coding format 4.3 Conformance
37、 requirements 4.3.1 Adjacent signal selectivity Purpose: To enable reception of a wanted signal in presence of other signals on adjacent frequencies that are transmitted with high EIRP from near-by adjacent orbital positions. NOTE 1: Signals transmitted from the same orbital position are under contr
38、ol of the satellite operator. Signals transmitted adjacent orbital position that is not near-by are suppressed by the antenna gain pattern. Specification: Adjacent signal selectivity is specified through an increase of the required signal to noise ratio caused by the adjacent signal. ETSI ETSI EN 30
39、3 372-2 V1.1.1 (2016-04) 7 The adjacent signal shall apply the same modulation as the wanted signal. Frequency offset and power level offset of the adjacent signal with regard to the wanted signal shall take the values given in table 1. F is the ideal signal occupied bandwidth. Table 1: Adjacent sig
40、nal frequency and level Frequency offset from wanted signal Power level offset from wanted signal -F - 4 MHz 10 dB -F - 2 MHz 4 dB -F 0 dB F 0 dB F + 2 MHz 4 dB F + 4 MHz 10 dB The required signal to noise ratio in presence of an adjacent signal shall be less than 0,4 dB higher than in absence of ad
41、jacent signals. NOTE 2: In case of amplitude or phase shift keying signals the occupied bandwidth of an ideal signal is F = Rs (1 + ), where Rsis the symbol rate and is the roll-off. NOTE 3: The case with frequency offset F represents carriers sharing a transponder, F + 2 MHz represents carriers on
42、adjacent transponders of a satellite, F + 4 MHz represents carriers on different satellites. Frequency offset is meant between centre frequencies of carriers. Verification: The test method specified in clause 6.1 shall apply. 4.3.2 Dynamic range Purpose: To allow a wide range of satellite EIRP and o
43、f ODU antenna diameter. NOTE 1: Besides satellite EIRP and ODU antenna diameter, the dynamic range covers the range of coaxial cable length and LNB gain. Specification: The IDU shall be able to process without degradation input signals at any level in a range of at least 40 dB. Verification: The tes
44、t method specified in clause 6.2 shall apply. NOTE 2: The absolute input level range appears in clause 4.2. 5 Testing for compliance with technical requirements 5.1 Environmental conditions for testing Tests defined in the present document shall be carried out at representative points within the bou
45、ndary limits of the declared operational environmental profile. Where technical performance varies subject to environmental conditions, tests shall be carried out under a sufficient variety of environmental conditions (within the boundary limits of the declared operational environmental profile) to
46、give confidence of compliance for the affected technical requirements. ETSI ETSI EN 303 372-2 V1.1.1 (2016-04) 8 5.2 Interpretation of the measurement results The interpretation of the results recorded in a test report for the measurements described in the present document shall be as follows: the m
47、easured value related to the corresponding limit will be used to decide whether an equipment meets the requirements of the present document; the value of the measurement uncertainty for the measurement of each parameter shall be included in the test report. 6 Test methods 6.1 Adjacent signal selecti
