Re: QAM64-100Meg - getting speeds less than 40mg
dBmv power levels are a relative measure. Actually 0 dBmv represents a power input of 1.33E-08 Watts at 75 ohms impedance. 3 dBmv represents twice that and -3 dBmv represents half that. I've posted a full explanation in the other place.
0 dBmv is ideal as a downstream power level.
