Due to some issue to the SDB2 DAQ-BOX occurred when we manually unlocked this afternoon at the end of the shift, a reconfiguration was needed (exact details will be eventually posted in a dedicated entry).

Most of the demodulation phases related to SDB2 needed to be retuned.

• , we tuned:We checked DARM phases along the acquisition up to CARM null 3f; According to the monitor online and the line within the spectra between DARM err signal I and Q quadratures
  • step 2/3: from 4.22 rad to 4.5
  • step 3/3: from 3.8 to 4.1 rad
  • CARM null 3F :  from 3.82 rad to 3.95 rad
• Regarding DIFFp demodulation phases, we tuned online by moving the WE TY/TX. It seems the sign was wrong so needed from -1.2 rad to -2.7 rad. Since we weren't able to move to fbw, we are not completely sure it is the right value, so we left the older values (-1.2 rad);
• it looked also 169 MHz phase (MICH/SRCL) needed to be tuned: from - 0.95 to -0.75 rad. (also this to be checked)

The recovery still need to be finalized.

The engament of the DIFFp is as usual, nothing was commented.
