Although the EVM GUI does not allow direct access to the voltage levels and timing configuration of the ADC digital interface, the EVM GUI provides users with high-level control over the ADS8332 sampling rate, channel selection, and channel scanning.

Figure 6-3 shows the interface configuration pane at the left, through which various functions of the ADS8332 are exercised. These are global settings, and persist across the different GUI testing tools, and the GUI pages listed in the top left pane.

The Channel Select Mode field allows the user to choose to capture data from a single channel or to automatically scan through the channels.

The Select Channel drop-down menu allows the user to select the single channel to sample (if in manual channel select mode) or to select the start channel for the automatic scanning (if in auto channel select mode).

The ADS8332EVMV2 device supports sampling rates from 500 kSPS down to 20 kSPS. The Sampling Rate field allows the user to type in the desired sampling rate in samples per second (SPS).
