Developing real-time AIDA data synchronisation test using MIDASsort To illustrate AIDA readout, ADC and discriminator data from a pulser event is plotted as a function of the 100MHz AIDA internal timestamp (1us/channel) Attachment 1 - nnaida8 number of ADC and discriminator data items Attachment 2 - nnaida1-24 number of ADC and discriminator data items Attachment 3 - 4*(FEE64 module # - 1) + ASIC # (ADC channels 0-95, disc channels 100-195) versus timestamp (1us/channel) The spectra clearly illustrate - 500kHz ADC readout cycle - discriminator readout precedes ADC readout by ~18us (this figure will be shaping time dependent) - after-pulse due to pulser injection via simple charge terminator (no pole zero correction) ~84us after start of ADC readout (this figure will be pulser decay time and shaping time dependent) Note events were identified (delimited) by time periods > 2us between successive ADC data items
