Attendance: MA, SK, HP, KY, TB, VS, KN

Minutes:

SK/HP:

• Updated TOP Feat Ext code, fixed some bugs, swapped endianness, added output words conforming to the data format Production Debugging v4.1 - Vasily to check and confirm the same with the FW version that was last run at KEK for data taking (84-93/78-23).
• Intergral (word/bits) in data format is Amplitude x 4 - SK will add this to the output data.
• Broken packet counter (Vasily will let us know the address for this counter) comparison with and without PS bypass - this increments if there are data packets missing, eg. when the ASIC footer is missing from data. Matt suggested to add similar functionality in the code for checking and counting the broken packages -- SK/HP will try to implement this in the next version along with the pedestal subtraction.
• Matt checked and the board to inject the fast pulses into FTSW as triggers is at KEK, and another board can be arranged in a week's time for higher occupancy tests. KY asked to carry out these high-rate/high occupancy tests at KEK instead. For now, we will do this. But having an option to be able to stress test could be helpful in the future.
