Measuring Harmonics (Option 002)

The analyzer has the capability of measuring swept second and third harmonics as a

function of frequency in a real-time manner. By using trace math, the second/third

harmonic response can be displayed directly in dBc (dB below the fundamental or carrier).

The ability to display harmonic level versus frequency or RF power allows "real-time"

tuning of harmonic distortion.
