About the ADC range,
According to the elogs, DARM = AS55Q/400. So in the current level, the error has +/40cntpp (even if I ignore the whitening).
The arm transmission this time was 0.10.3. This will go up to 100~300. So we potentially increase the AS55Q optical gain by factor of 1000.
So we get +/40000. This is already too much. If we consider the whitening, the situation is more tough.
We need to lower the whitening gain. If it is not enough, we need to lower the power on the PD.
How much was the whitening gain for AS55 this time?
