AC TESTING—FFT CAPTURE
Figure 15 shows the FFT tab. The FFT tab analyzes the
performance of an ADC in the frequency domain. The FFT tab
tests the traditional ac characteristics of the converter and displays
a fast Fourier transform (FFT) of the results. The FFT tab shows
a plot of the computed FFT data.

The Spectrum Analysis pane contains further information
about the analysis, such as the calculated values of signal-to-
noise ratio (SNR), signal-to-noise-and-distortion (SINAD), and
total harmonic distortion (THD) (see Figure 15).
The user can choose to display the information for one, several,
or all eight channels in the FFT tab using the ADC 1 ON/ADC
1 OFF to ADC 8 ON/ADC 8 OFF buttons.
