Detailed Description

Module to compute average power spectrum of noise.

Author

A. Bryant, M.Vignati, C. Tomei

Used for pulse amplitude algorithms

• Config example:

    module NoiseAvgPowerSpectrum
    verbosity = info
    enable = true
    ValidityKind = dataset
    ValidityStart = 6001
    ValidityEnd = 6001
    WindowType = welch
    WindowCoherentGain = 2
    Output = avgnoise.root
    endmod
    

• Parameters:
  • ValidityKind [string = "dataset"]: defines the kind of validity range for the nps, can be run or dataset
  • ValidityStart: first run (or dataset) of validity
  • ValidityEnd: last run (or dataset) of validity
  • Output [string = avgpulses.root] output for nps, may be root file or DB
  • WindowType [string = "None"]: type of window used for windowing (default is rectangular)
  • WindowCoherentGain [int = 2]: defines window normalization
• Optional parameters: PulseLabel [string = "DAQ@Pulse"]: label of the QPulse storing the event waveform.
• Reads:
  • RawTriggerPulse
  • QFiltersData
• Writes:
  • Average NPS to file or to DB (if fOutput = DB)
