WebAug 11, 2024 · 0 dBmV is said to be ideal (a reference point). -15 dBmV is not really great (and should be avoided) and breaks more easily when noise is present. Your -12 dBmV is not a great value, but your SNR indicates a rather clean line. Unfortunately, your modem doesn't show codeword stats (bit errors), so you don't know if there is intermittent noise. WebS dBmV = 20 log 10 E A 1-mV signal across a pure resistance has a level of 0 dBmV. Signals weaker than 1 mV have negative dBmV values; signals stronger than 1 mV have positive dBmV values, assuming the impedance remains a pure resistance and remains constant.
