6.3 Time Domain Display Tool
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.
The user can trigger a capture of the data of the selected number of samples from the ADS9120, as per
the current interface mode settings using the capture button as indicated in
Figure 12 . The sample indices
are on the x-axis and there are two y-axes showing the corresponding output codes as well as 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.
