Re: Balancing Return

Trilithic 860 basically has a 8 frequency RSVP built into it.

More resolution is better (ie. sweep), but the 860 will get you in the ball park.   take a reference reading at your node, then match your return readings on all subsequent amps/le's.    set your upstream tilt first by getting the upstream channel readings to be the same from the lowest upstream frequency to the highest upstream frequency by changing the reverse eq's.  then pad the return to match the levels you had at the node.    Make sure you consider where you are taking your return test at, and if you have return padding that matches the forward signal directors, take that into account for you readings.   If its all gainmaker, it should be really easy.   Just make sure you take your return tests from the main output port, as it will likely always have a zero return input pad.

Word to the wise.  Test return on all active ports of the amp before you move on to the next one.

Make sure the SST in the headend or hubsite is setup to do upstream testing on frequencies not currently occupied by active 2 way devices.
