Figure 1-3. SLM-5650C / SLM-5650C-ODU Block Diagram
Figure 1-3 depicts the functional block diagram for the SLM-5650C and SLM-5650C-ODU. Both
modems have been designed to accommodate a wide range of currently required features, and to
support both near- and long-term advances in software-defined radio technology as well as
advances in FEC technology.
The user has the ability to:
•
Utilize an extensive array of built-in test capabilities
•
Easily upgrade the modem’s operational capabilities in the field
•
Easily update the modem’s firmware in the field
•
Use a wide range of flexible remote control options
As shown in Figure 1-3, both modems accept Ethernet data to modulate an L-Band carrier. The
demodulator receives and demodulates the L-Band carrier. Recovered data is then output on the
Ethernet interface.
The Tx and Rx functions are independent with respect to modulation and coding. Both modems
can operate in simplex (Tx only or Rx only) or duplex mode.
