Evaluating Performance with the ADCPro Software
After an acquisition, the Read Alarms button allows the user to read back the specific alarms that
reported a fault. When the button is pressed, the firmware uses the sticky register read command; once
the alarms are read, they are set back to zero. Each channel has two alarms, a high alarm and a low
alarm; both are placed side by side in the alarm list. When the Read Alarms button is pressed, the LED
corresponding to the alarm limit that was breached is enabled.

Collecting Data
Once you have configured the ADS8638 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
ADS8638EVM-PDK plug-in disables all the front panel controls while acquiring, and displays a progress
bar.

Troubleshooting
If ADCPro stops responding while the ADS8638EVM-PDK is connected, try unplugging the power supply
from the PDK. Unload and reload the plug-in before reapplying power to the PDK.
