The time domain display tool allows visualization of the ADC response to a given input signal. This tool is useful for both studying the behavior and debugging any gross problems with the ADC or drive circuits.

To trigger a capture of the data of the selected number of samples from the ADS9224R, as per the current interface mode settings, use the Capture button shown on the left pane of Figure 6-5. The sample indices are on the x-axis. The two y-axes show the corresponding output codes, as well as the equivalent analog voltages based on the specified reference voltage. To display channel A (Ch A) data or channel B (Ch B) data, select the proper channel, as shown in the top right section of Figure 6-5. Switching pages to any of the analysis tools described in the subsequent sections triggers calculations that are performed on the same set of data.
