Since the 2025-09-12-10h50m34-UTC, there are some issues related to the data provided by the DAQ_DEMOD_SQZ_PLL demodulation board:

This morning several trials were made to reconfigure the faulty demodulation board without success.

As a result, the phases referenced in the DAQ and related to the SQZ clocks are not correctly extracted, consequently signals demodulated from the SQZ clocks are not correctly constructed

More investigations will be done during the next maintenance
