Once you have configured the ADS1274 for your test scenario, press the ADCPro Acquire button to start

the collection of the number of datapoints specified in the Test plug-in Block Size control. The

ADS1274EVM-PDK plug-in disables all the front panel controls while acquiring, and displays a progress

bar as shown in Figure 31.

For more information on testing analog-to-digital converters in general and using ADCPro and Test

plug-ins, refer to the ADCPro User Guide.

If ADCPro stops responding while the ADS1274EVM-PDK is connected, try unplugging the power supply

from the PDK. Unload and reload the plug-in before reapplying power to the PDK.
