Find the downstream and upstream power in dBmV and the Signal to Noise Ratio (SNR) and report back.
The downstream signal power should be between -10 and +10 dBmV. (Some say between -15 and +15 but I feel that is pushing your luck)
The SNR should be 35 or more.
The upstream power level should be less than 55 dBmV.
Apparently, Comcast has tightened the tolerances for DOCSIS 3.0
Signal to Noise Ratio (SNR): 32 dB - 50 dB
Power Level: -5 dBmV to 5 dBmV
Upstream Power: 32 dBmV - 50 dBmV
What do you think?
