Measuring Swept Harmonics (Option 002 Only)
The analyzer has the unique capability of measuring swept second and third harmonics as a
function of frequency in a real-time manner. Figure 2-56 displays the absolute power of the
fundamental and second harmonic in Figure 2-57 shows the second harmonic’s power
level relative to the fundamental power in Follow the steps listed below to perform these
measurements.
