适用范围：This International Standard applies to the outdoor unit of a receiver for the direct reception of satellite broadcast transmissions in the 12 GHz band. The channels are those defined by WARC BS-77 and RARC SAT-83 and the systems are those defined in CCIR Recommendation 650. The object of this standard is to define the conditions and methods of measurement to be applied. The standard does not specify performance requirements. An outdoor unit normally comprises three main parts, the antenna, the depolarizer and optional orthomode transducer (OMT), and the SHF converter as defined in clause 1.3. The methods of measuring the electrical properties described in this part of the standard apply particularly to the outdoor unit or the SHF converter. Methods of measurement on the associated DBS tuner unit are described in Part 2 of this standard.
