SUMMARY:
1. It appears that this problem was due to RF environmental factors unique to CWEX11. It is not physical since we do not see noise on the Li7500 H2O signal or any other scalar.
2. We have no way of detecting whether noise occurred on the lower-rate analog channels.
3. Since we can fix the CWEX11 data in software (FFT; filter spectra; inverse FFT), we do not need to know the source.
4. We are not sure that we will ever use the same serializers (or kryptons) again, but we should look for this noise again in any case.
5. IF we wanted to pursue this further, we could take the station to the turbine test station at NREL, though there still may not be exactly the same RF environment.
6. We should keep track of the frequency and amplitude of the noise while correcting the CWEX11 data. We also may get turbine operating parameter data (rotation speed?) from the wind farm operator. This log entry may be revisited with a check of whether these values are correlated.
