Today, the setup of the B2_PD2 demodulation at 1MHz and 2MHz has been completed (first part)
Below the performed actions
- the SIB2_dbox_bench configuration has been updated
- to remove the B2 PD2 demodulation at 1xF4MHz and 2xF56MHz
- to add the B2 PD2 demodulation at 1xF1MHz and 1xF2MHz
- operations done at 2025-03-18-07h48m03-UTC . As consequence all the B2 PD2 demodulated signals have been reconfigured
- the 100MHz phase jumps from -2.904 rad t0 -2,908 rad . So it seems that none phase adjustment is required for B2_PD2
- the SIB2_Photodiodes configuration has been updated
- to remove the B2 PD2 last demodulation stage for the 1xF4MHz and 2xF56MHz
- to add the B2 PD2 last demodulation stage for the 1xF1MHz and 1xF2MHz
- operations performed at 2025-03-18-07h53m57-UTC
- As the B2 PD2 8MHz signals are sent to the SSFS mezzanine. to recover the correct synchronisation the SSFS mezzannine has been reconfigured too
- operation performed at 2025-03-18-08h20m49-UTC
After these operations, the RFC has been successfully locked . Its remains to check if the ITF re-locks and if the B2_PD1_1MHz and B2_PD2_2MHz signals are correctly built
