1.3 Functional Description
External equipment, e.g., a modem, is connected to each internal converter module via a
standard, off‐the‐shelf coaxial cable. A coaxial cable is also used to connect the output for each
module to RF equipment either at the same location or at the antenna location.
When configured with the redundancy option, the system may contain two diode “OR‐ed”
internal power supplies for increased reliability, and microprocessor‐based Monitor and Control
(M&C) functions. Figure 1‐4 depicts the block diagram for a typical LBC‐4000 L‐Band Up/
Downconverter System application.
