SG4000 Installation and Operation Manual

You can configure the SG4000 return path using a variety of analog or digital transmitters and

up to two configuration plug-in boards in the return configuration board locations. Each board

has a specific function and transmitter combination associated with it and is clearly labeled.

The return configuration board, in location 2, services the analog transmitters in lid optics slots

3 and 4. The return configuration board in location 3 services the analog transmitters in lid

optics slots 5 and 6. For detailed information on the return path transmitters, see Section 4,

“Modules.”

The SG4000 return path and configuration boards provide the nominal input level to the return

path transmitters when 28 dBmV total composite power is present at the node housing ports.

Table 3-2 identifies and describes the SG4000 return-path configuration options.
