This morning the demodulation of the SDB2_B1p_QD{1,2} signals at 50MHz has been setup .
To allow this :
- In agreement with the ISC team the SDB2_B1p_QD_{1,2} demodulation at 18MHz has been removed
- The fpga demodulation frequency has been set to exactly 8 times the one use to demodulate the 6MHz to allow the DAQ-LNFS phase correction with the 8*6 MHz phase extracted at the LNFS level .
The channels SDB2_B1p_50MHz_{H,V}_{I,Q} are sent to the ASC_Acl server . The ASC_Acl server has been upgraped to acquire these new channels , of course the SDB2_B1p_18MHz_{H,V}_{I,Q} channels have been removed.
Only the demodulation mezzanines acquiring the SDB2_B1p_QD{1,2} channels have been reconfigured : as consequence only the SDB2_B1p_QD{1,2}_XMHz phases have to be adjusted.
