Estimating PSD Ratio Using Spectrum Analyzer

PSD Ratio or CnC Ratio can also be estimated using a Spectrum Analyzer capable of integrating
the signal power in a given bandwidth.
CnC Ratio (in dB) = Power
PSD Ratio (in dB) = (Power
= CnC Ratio – 10 log (BW
If the two carriers have same Symbol Rate / Bandwidth, then the CnC Ratio is same as the PSD
Ratio.
