Den noticed this, and will write more later, I just wanted to sum up what Alex said / did while he was here a few minutes ago....

 From my point of view during rfm -> oaf transmission through Dolphin we loose a significant part of the signal. To check that I've created MEDM screen to monitor the transmission errors in the OAF model. It shows how many errors occurs per second. For MCL channel this number turned out to be 2046 +/- 1. This makes sense to me as the sampling rate is 2048 Hz => then we actually receive only 1-3 data points per second. We can see this in the dataviewer.

C1:OAF-MCL_IN follows C1:IOO-MC_F in the sense that the scale of 2 signals are the same in 2 states: MC locked and unlocked. It seems that we loose 2046 out of 2048 points per second.
