6.2 Time Domain Display Tool

The Time Domain Display tool provides a 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 front-end drive circuits.

As per the selected interface mode settings using the Capture button indicated in Figure 6-3, the user can trigger a data capture of the selected number of samples from the ADS7953EVM-PDK. The sample indices are on the x-axis, and two y-axes show the corresponding output codes and the equivalent analog voltages based on the specified reference voltage. Switching pages to any of the analysis tools described in the subsequent sections triggers calculations to be performed on the same set of data.
