SDB2 readout

This morming, the followings actions were perfomed on the SDB2 readout:

  • the unused demodulations were removed for
    • B1s1 6MHz, 12MHz and 56MHz
    • B1s1P 6MHz
    • B1s2P 6MHz
    • B1p 119MHz
    • B5 119MHz
    • the SDB2_DBOX_bench, SDB2_Photodiodes and the LSC_Acl configurations were upgraded accordly
  • the B1s2 demodulations were actived at the level of SDB2_photodiodes,
  • the demodulations of the B1_PD1 and B1_PD2 photodiodes were configured and activated at 6MHz, 8MHz and 56MHz . For each beam and photodiode, the I,Q, magnetude and the phase channels are computed
  • The B1p quadrant photodiodes are now demodulated at the 7MHz squeezer  frequency. To allow this, the decimation before the DSP filtering is now done at 500kHz instead of 1MHz previoulsly
  • All the {beam}_sample channels are now available for each demodulated channels: longitudinal and angular  photododiodes
