All the calibration steps require a similar setup to
(more information about setup in section
Appendix B - Requirements for phycalibrationtool.py
)
"Equalization" and "Gain Calibration" steps must be run iteratively and require the user evaluation (ripple
and power measurements). On the other hand, the PHY Calibration Tool will automatically look for the
best values on "Max RMS Process" and "Thresholds Process" steps.
CAUTION
In each iteration, equalization must be reset in order to restore default values.
