Re: aurora node, multiple return freq's (return p

I'm not sure which method they are using for load balancing, but if they are splitting the upstream between 2 ports you could have a padding problem on one of the 2 legs.

If they are using a logical splitter (within the in the 10K) then you may have to inject a CW and measure the input at all frequency to ensure flatness into the port. In this case you most likely will see tilt between the return path receiver card output and uBr input.

Your system sweep may show good if it's not seeing the entire cable/splitter loss within the headend. The sweep should be looking at the same cable/passive loss at the CMTS to sweep the return from the node to the CMTS properly. To resolve a problem like this you can EQ the return either in the node (if it has the option) or on the combiners/splitters.

I've personally seen as much as 3dB tilt between the node transmitter and uBr input.
