Revision as of 12:43, 29 November 2016

  • Check performance of the FADC250 firmware
- significantly better emulation of the fadc algorithm (use cosmic, led pulser data)
- some 'minor' issues may still exist (Sean)
- take data with different fadc settings (NSAT, ...)
  • Check discriminator firmware
  • High rate trigger performance
- install new F1TDC firmware on some modules of the TAGH/TAGM crate
- expect more robust performance at high rate
(test performance using external TS FP generator)
- check busy distribution from tagger crates


  • Modifications in config files
- initialization and readout (trigger) of the CompCal
- config files for the play back
