Pierre, Yuhang
After the design/talk/discuss with Matteo, Eleonora and us, Pierre redesign the circuit and we implemented it. Now the procedure is just to press 'reset' button and then MZ and GRMC will be locked in sequence. Please also remember to use 'auto' mode of GRMC and 'man' mode of MZ and put them both in 'lock' state.
Then we measured the open loop transfer function of MZ.
