2.3. Functional Description
The relationship between the functions of the receiver and the connectors is
shown in the block diagram below.
Figure 2-2 Functional Block Diagram
The receiver connectors are detailed in
Section 4 Rear Panel Connectors.
Multiple units can be cascaded using ASI input and outputs. The use of both
MRC (Maximum Ratio Combining) of the received COFDM signals and the ASI
packet diversity, the combining of two ASI streams to produce a stream with
fewer errors than either input; provides a flexible and extendable receiver
system.
When ‘External ASI & Diversity’ is configured as the unit input, Demod 4 is
switched to external ASI, so the 16-way RF input is reduced to 12-way plus
external ASI and the external ASI cannot be packet switched. Packet switching
is only possible if the external ASI is supplied from a separate Quantum with a
single Demod only.
