Let me explain how I do it.
First our amp. are equipped with -20 dB directional test point.
We insert the sweep gear for a + 15 dBmV input, plus the 20 dB test point, so + 35 dBmv return sweep level.
Our headend return gear is set for 0 dBmv at the CMTS.
Most of the time we need to install a return pad for the right level and a return EQ.
The return EQ is for a flat input at the CMTS.
The return pad is for the right return operating level.
You should always install the return pad at the output of the return IC.
Hope this help.
