+) Step 1 with HV OFF, with auto reset delay 24ns:\\
+We changed LV power supply from table top to caen.
+Only the all channels enabled s curved are measured.
+We obtain 4-5 dac unit less noise for each petiroc.
+==== Mesures au beam dump 02/11 ====
+=== Organisation of code ===
+Gerald will patch the code in /home/acqcmsmu/FEB_DAQ/python_src_BC0id_01092021/python_src_BC0id
+ToIncludeInEqualization.py
+One should able to set the mode of Pedestal calculation:
+  * Single: True for channel/channel , False all channels ON
+  * p_type: Petiroc type 0:A 1:B 2:c
+  * r_type: Reset type, 0 FPGA Reset, 1 Autoreset (for PETIROC 2C only)
+=== Pedestal measurements ===
+== FEB #6  Chambre 188 ==
+The HV is set to 5 kV on both gaps. The LV is done with desk power supplies
+We do a first pedestal alignment channel / channel:
+  p_type=2  # 0: A , 1: B , 2:C
+  p2C_autoreset_ON=True
+  single=True # scurve channel by channel or all channels at the same time
+  nDacTarget=-1 # -1 means find target automatically, otherwise put a DAC value  to reach (example 400)
+  P2B_FSM_parameters=[3,2,2]
+  P2C_resetDelay_parameter=4
+Results are in:
+  /home/acqcmsmu/FEB_DAQ/python_src_BC0id_01092021/python_src_BC0id/Results/
+  dac6bConfig_FEB6_188_single/
+  SweepData_FEB6_188_single/
+With those settings we make a pedestal all channels ON run 1635856021966 in SweepData
+The sweep data files are in
+  /home/acqcmsmu/FEB_DAQ/python_src_BC0id_01092021/python_src_BC0id/Results/
+  dac6bConfig_FEB6_188_all/
+The channels and summary png are in the same directory
+We observe a noise ~ 45-55 DAC10B counts (a bit high)
+Here the turn on is around 455 and the target is 409 , so 45 DAC
+{{ :petiroc2c:scurve_channels_fpga_2_top_1635856021966.png |}}
+We repeat the run with different grounding  run 1635857964615
+Same results so we create a state in DB
+  RE41_188_FEB_6_BeamDump_LM
+Version 2 is load with Scurve studies alignement and +60 from Target
+We then set the HV to 7.1 kV and try a run 1255 in /data/beamdump/raw
+ --- //[[laurent.mirabito@gmail.com|DAQ user]] 2021/11/02 14:33//
+For the moment no beam so difficult to conclude
+Few beam seen but weird trigger
+Run 1256 idem with good trigger but still weird data
+I create a "bad" state with alignement with autoreset but FPGA reset settings it's version RE41_188_FEB_6_BeamDump_LM 3
+Run 1257 is with this state, not a single channel seen except 32 (BC0) and 33 (Trigger)
+ --- //[[laurent.mirabito@gmail.com|DAQ user]] 2021/11/03 05:37//
+State  RE41_188_FEB_6_BeamDump_LM 4 is identical with trehsold = Target +10
+Lot of channels seen but only on FPGA 0 and first channels (0-10)
