7. Select Recording Options and click the Probe Settings tab.
8. Click Auto Configure to display the Calibrate SummitT3‐8 Dialog.
Manually set the polarity for each lane in this dialog with the polarity settings in the
Link Dashboard. Link Width, Speed and Polarity must be set the same as the current
state of the link. Checking the Quick Calibration option will sweep through the CTLE
setting only. If unchecked it will sweep through both CTLE and DFE. Using Detect Idle
Errors will increase the calibration time but it will improve/optimize calibration
results.
