Complete the following steps to configure the Distortion step and the
Amplitude and Levels step.
1. Double-click the Distortion step in th e Project View. The Step Setup
dialog box for the Distortion step appears, as shown in Figure 3-3.
Figure 3-3. Distortion Step Setup Dialog Box
On the Configuration tab, the settings indicate that the Distortion step
receives a time-domain waveform signal as an input, performs a power
spectrum on the signal to convert it to the frequency domain, and
computes the total harmonic distortion (THD) and fundamental
frequency of the signal. The step generates three measurements as
outputs—the spectrum, the THD, and the fundamental frequency of
the original time-domain waveform input.
2. If the context help does not appear on the right side of the screen, click
the Show Help button, shown at left, to display complete reference
information about the step. The upper half of the context help displays
information about the step, and the lower half of the context help
displays information about an object when you move the cursor over
the object.
