Domaine dapplication Cette partie de la norme, qui est complmentaire de la premire partie, CE1 835-1-1, dcrit les mthodes de mesure applicables aux faisceaux hertziens terrestres qui utilisent une modulation numrique. Lobjet de cette partie est de fournir des mth

30、odes de mesure recom- mandes pour valuer les caractristiques essentielles des faisceaux hertziens terrestres et de leurs sous-systmes. Elle doit tre utilise conjointement avec la premire partie, CE1 835-1 -1. Lorsquil faut dcrire une mesure commune aux faisceaux hertziens terrestres et aux stations

31、terriennes, rfrence est faite la section approprie de la premire partie, CE1 835-1-1, et seuls les aspects de la mesure qui sont spcifiques aux faisceaux hertziens terrestres sont dcrits dans les sections de cette deuxime partie. Les mesures dcrites dans les sections suivantes de cette partie ne son

32、t ni obligatoires ni limitatives; un choix de mesures peut tre fait dans chaque cas particulier. Par exemple, pour des dbits binaires, infrieurs 34 Mbit/s, on peut estimer que des mesures complexes, comme celle de la signature, sont inutiles. Dautre part, des mesures plus compliques ( ltude) peuvent

33、 tre ncessaires pour des modulations complexes comme la MAQ-64. Lorsque les paramtres ou les mthodes de mesure sappliquent exclusivement aux faisceaux hertziens terrestres, ils sont dcrits en totalit dans les sections appropries de cette partie. 2.

METHODS OF MEASUREMENT FOR EQUIPMENT USED IN DIGITAL MICROWAVE RADIO TRANSMISSION SYSTEMS Part 2: Measurements on terrestrial radio-relay systems SECTION ONE - GENERAL scope This part of the standard, which is supplementary to Part 1, IEC

36、 835-1 -1, describes methods of measurement applicable to terrestrial radio-relay systems using digital modulation. The object of this part is to provide recommended methods of measurement for assessing the essential properties of terrestrial radio- relay systems as well as the associated sub-system

37、s and it is intended to be used in conjunction with Part 1, IEC 835-1-1. Where measurements common to terrestrial radio-relay and satellite earth station systems are required, reference is made to the appro- priate section of Part 1, IEC 835-1-1. In such cases, only those special aspects of the meas

38、urement appropriate to terrestrial radio- relay systems are described in the sections of this Part 2. The measurements described in the following sections of this part are neither mandatory nor limiting; a choice of measurements can be made in each particular case, e.g., for bit-rates less than abou

39、t 34 Mbit/s, the signature as well as some of the more sophisticated measurements may not be of interest. On the other hand more comprehensive measurements (under consi- deration) may be required for complex modulation methods e.9. 64-QAM. Where parameters or methods of measurement are applicable on

40、ly to terrestrial radio-relay systems, they are fully described within the appropriate sections of this part. Normative references The following IEC publication is quoted in this standard: Publication No. 835-1-1 (1990) : Methods of measurement for equipment used in digital microwave radio trans- mission systems, Part 1 : Measurements common to terrestrial radio-relay systems and satellite earth stations.
