|Commissie||Geluid, beeld en multimedia-apparaten en -systemen|
This part of IEC 1079 applies to the tuner unit of a receiver for the direct reception of satellite broadcast transmission in the 12 GHz band. The channels are those defined by WARC BS-77 and RARC SAT-83 and the systems are those of CCIRR 650. The object of this part of IEC 1079 is to define the conditions and methods of measurement to be applied. This part does not specify performance requirements. The tuner unit comprises the channel selector and FM demodulator. The input to this unit is a group of intermediate frequency signals, usually in the range 1 GHz to 2 GHz, which is provided from an associated outdoor unit. The outdoor unit includes at least a microwave antenna and the frequency converter to the first intermediate frequency.
