These new services are constantly being developed and improved by the providers. To utilize the services, it may occasionally be necessary to update the software of the digi- tal receiver.
Transponder:
Located on the satellite, serves to process one or several programmes. It receives the signal from the ground station, amplifies it, and broadcasts the signal back to earth. Universal LNC:
Used for reception of the frequency ranges FFS (10,70 - 11,70 GHz), BBS (11,70 - 12,50 GHz) and FFS High Band (12,50 - 12,75 GHz). The entire range is divided into two bands:
Low Band: 10,70 - 11,80 GHz; LOF 9750 MHz High Band 11,70 - 12,75 GHz ; LOF 10600 MHz Operating voltage:
LNCs are supplied with power via the coaxial cable. To this end, the receiver provides a voltage of 14 or 18 Volts Intermediate Frequency:
The frequency range broadcast from the satellite cannot be transmitted via cable. It is therefore converted by the LNC to an intermediate frequency range of 950 to 2150 MHz. This allows the signal to be transmitted, and processed in the digi- tal receiver.
1. IF = 1st Intermediate Frequency
