Operating Instructions
There are no specific operating instructions for the SignalOn Return Path Amplifier. Once the amplifier is installed, it will
perform its designated RF signal management function without further attention. As detailed below, the amplifier includes
convenient Monitor (MON) ports where test equipment can be connected to the system as necessary.
3.1.
Monitor Test Ports
Two 20 dB monitor test ports are standard on the Return Path Amplifier, one before RF amplification and one after.
3.2.
Reverse Path
SignalOn modules can balance the reverse path combined signals and provide the balanced power from the reverse path
receivers to signal processing equipment (e.g., cable data modems, HDTs, etc.). (See example in Figure 3.)
