7.9 Satellite Modulator Option Card (AVP 3000 Voyager Only)
7.9.1 General
The satellite modulator option card is a module that takes MPEG Transport Streams
on its input, either a TS generated in the unit, or passed through from an ASI input,
and provides a modulated output either in L-band (950 – 2150 MHz) or in IF band
(50 – 180 MHz) according to the DVB-S, DVB-DSNG, DVB-S2 or DVB-S2X
specification. The output signal can be fed to an up-converter for mixing the signal to
the appropriate satellite channel. The module is also capable of powering the
downstream up-converter.
Figure 7.10 Satellite Modulator Option Card
To increase reliability, the satellite modulator option card can take two input
Transport Streams and encode and modulate one of them at a time. If the Transport
Stream being modulated is lost for some reason, the module can switch
automatically to the other Transport Stream input and continue the transmission
using that.
7.9.2 Interfaces
The Satellite Modulator option card has the following connectors:
•
One 50
Ω female SMA L-Band input connector.
•
One 50
Ω female SMA L-Band main output connector.
•
One 75
Ω female F-type L-Band output connector for monitoring purposes.
•
One 75
Ω female BNC IF main output connectors.
•
One 75
Ω female BNC IF output connector for monitoring purposes.
The L-Band input can be used for inputting a modulated L-Band signal to the
module. The module then can combine the input and its own modulated output and
feed a common up-converter with the combined signal.
