Example 4: Harmonic Distortion
Figure 2-16 Peak of Signal is Positioned at Reference Level for Maximum
Accuracy
Place a second marker on the second harmonic
1. Set the peak threshold above the noise:
a. Press PEAK SEARCH, MORE 1 OF 2, PEAK THRESHLD.
b. Adjust the dashed line to a level above the noise using either the
step keys or the knob.
2. Activate the second marker:
a. Press
PEAK SEARCH, MARKER DELTA, NEXT PK RIGHT.
This places the anchor marker on the fundamental, and a second
marker on the peak of the second harmonic, as shown in Figure 2-17 on
page 70.
