The station is equipped with four SAT IF inputs, one RF output and one test
output (–25 dB). It is preset to receive the most popular ASTRA transponders.
Different programming is possible at any time.
Each of the 16 tuners can be assigned to any SAT input.
Using an adequate CA modules scrambled channels can be descrambled via
tuners "1"…"6".
The kind of modulation at the output can be selected between QAM
or
COFDM
(menu System > Firmware).
—> Note for COFDM outputs:
Since satellite transponder can transmit higher data rates than DVB-T
transponder, you need to remove Services menu from the data stream
in menu "Filter & CA"!
Select SD transponder in menu input.
Just two HD services with high data rates may lead to an output data
overflow in COFDM.
