What was in the DAQ logs?
From the DAQ logs (/cds/group/pcds/pds/mec/logfiles/2023/05):
- We see occurrences of
SrpV3::readRegister _pgp→read failed!in Quads 2 and 3. - The majority of these occur immediately after timestamped
SrpV3::read select timed out!errors. The occurrence of the latter errors are listed in parentheses. - The exceptions are when a
SrpV3::read read returned <NN>, we were looking for 7 uint32serror is seen just before. These are also timestamped.

What was in the Archiver Data?
The archiver data was searched for Epix10K channels that changed by 20% or more between successive entries. Here are the events for Quads 2 and 3:
Here is a plot of the ASIC_ANA_CUR data. Note that this (so far) just looks at the Quad data, not for the MPOD.
