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.

Yes - there have been multiple attempts to re-calibrate nnaida7 ADCs

Note *all* ADCs were calibrated before the most recent FEE64 power cycle.

It is not unusual for ~1-3 FEE64s to fail ADC calibration tests following
a power cycle - there is no obvious pattern to which ADCs fail or which (if
any) will be successfully re-calibrated.

16:43  Leakage currents OK - see attachment 1
