Measuring the power in an information-carrying signal relative to the power in the surrounding noise is a common task in many radio frequency applications, in particular for the satellite and cable television industries. This video explain what carrier to noise measurements are, the difference between carrier to noise and carrier to noise density, and how they are performed using a spectrum analyzer. A brief discussion of the difference between carrier to noise and signal to noise is also provided Understanding Basic Spectrum Analyzer Operation: • Understanding Basic Spectrum Analyzer...
