Dave Barker and I checked the status of HAM3-ISI's test points this morning. We noticed they were overloaded. Dave restarted H1-DAQ and they came back to normal. It seems like H1-DAQ was not restarted as it should have been after the model changes of last week.
Spectra measured on HAM3-ISI make sense again. I tried most combinations of ISO/blend filters on HAM3-ISI today. I attached a sum-up plot of HAM3-ISI isolation performance in the following configurations:
1- No control
2- Damping only
3- Damping + "old" blend* 250mHz + "old" ISO level 2
4- Damping + "newer" blend** 250mHz + "old" ISO level 2
5- Damping + "newer" blend** 250mHz + LLO HAM5 ISO level 2
ISO=Isolation filters
*: old blend filters - SVN revision 6036
**: newer blend filters - SVN revision 6187
