The ADC captured data is displayed in the major center portion of the GUI. The data display panel has four display control drop-downs. The data type drop-down allows the user to display the results as Codes, Bits, Real FFT or Complex FFT as shown in Figure 3-32.
The Codes option will display the data as actual digital codes. The Bit option will show the values of the individual ADC output bits and displayed as if it were captured by a logic analyzer.
The Channel drop-down selects which channel of a multi-channel ADC is to be displayed as shown in Figure 3-33.
When in the frequency domain mode, the GUI provides a windowing function to be applied to ADC captured data in the Window Display drop-down menu (Figure 3-34), Rectangular Window applies a unity gain to all data points of the captured data. A Hanning Window, Hamming Window, or Blackman-Harris Window function can be applied to the captured data for situations where the ADC output data rate and the input frequency are not or cannot be set precisely to capture an integer number of cycles of the input frequency (Coherent frequency).
