MDM9000 Satellite Modem
10.6 Demodulator
The demodulator receives the RF signal on L-BAND RX A, L-BAND RX B or IF RX.
Also make sure that the symbol rate and roll-off factor matches with the values set on the modulator
site. When these values do not match, the demodulator cannot lock, in this case an alarm RX-LOCK
is raised.
The demodulator is capable of receiving DVB-S2 (by default) and DVB-S2X or S2 Extensions.
The active RX interface provides DC power and frequency band selection signals compatible with
most professional and commercial LNBs.
After demodulation the baseband frames are forwarded towards the "BBF over IP out" block or to
the "Decapsulation" block.
