You can use the arrows on both sides of the bar chart to scroll through the chart, or you can
press the
Scroll
softkey and turn the
Entry
knob. The table and chart always scroll together; if
row 3 in the table is highlighted, the bar for harmonic 3 will turn blue, as shown below.
Discrete Fourier Transform (DFT) Configuration
The Harmonics sidebar contains several DFT values near the bottom. To configure the DFT
during a Harmonics analysis, press
[Math]
to display the following softkeys.
The DFT is automatically configured as Math waveform 4, and you can use the remaining
softkeys to configure the source, X-axis span and center, and vertical units (Decibels or RMS).
For example, a span of 3 kHz with a center of 2 kHz would go from 0.5 to 3.5 kHz.
You can also use the fourth and fifth softkeys in this menu to
specify the X-axis as start and stop frequencies if you prefer.
