Concerning nnaida7 and the failure of calibration..... have you tried to calibrate it using the FADC Align  & Control ?
If it still fails then there is a question about the quality of the clock signal being received by this module.
I will log through and look at the console log for any anomolies but please try and calibrate.
Let me know if you wish me to take remote control.
