5.3.6 RETURN LOSS, Remote RETURN LOSS
Return loss is the ratio between transmitted and reflected signals at the transmission
end. High return loss rates are often caused by local impedance mismatching and
decrease the signal strength on the receiver end.
The main result is given in dB as the worst case margin to the test standard limit.
