The calculator does NOT calculate 100% correct values but should give a good indication of the carrier to noise of a "unknown" cxr. There could be more inaccurancy in the measurments than the calculations.

Calculation used:

CNUNKNOWNCXR=CNKNOWNCXR+ (EIRPUNKNOWNCXR-EIRPKNOWNCXR)+10*LOG(SYMBOLRATE KNOWN CXR/ SYMBOLRATE UNKNOWN CXR)

1dB= 30dBm
YdB= XdBm-30dB
