Michael and Yuhang

Today we found we couldn't lock FC with GR. After checking error signal, I found the phase is not optimized. Then we reload DDS1 with the good phase, we saw good shape GR error signal. Checking from rampauto EPS2, the error signal pk-pk is 3.24V.

This DDS1 phase change is very strange. It seems to happen by itself without power off/on.
