10.1.10 Collecting Data
Once you have configured the ADS1259 for your test scenario, press the ADCPro Acquire button to start
the collection of the number of data points specified in the Test plug-in Block Size control. The
ADS1259EVM-PDK plug-in disables all the front panel controls while acquiring, and displays a progress
bar as shown in
Figure 39 .
Figure 39. Software Progress Indicator
For more information on testing analog-to-digital converters in general and using ADCPro and Test
plug-ins, refer to the
ADCPro User's Guide .
10.2 Troubleshooting
If ADCPro stops responding while the ADS1259EVM-PDK is connected, try unplugging the power supply
from the PDK. Unload and reload the plug-in before reapplying power to the PDK.
