First there is the Event Builder header for each trigger frame

• Event Builder Header 0 (32-bits)
  
  • 31:00 = Event Counter (starting from 1)
• Event Builder Header 1/2 (64-bits)
  
  • 23:00 = Timestamp bits 23:0
  • 55:32 = Timestamp bits 47:24
  • A 48-bit running counter gets reset to 0 at the start of each run
  • This number will be the same across all DPMs for a given trigger event
• Event Builder Header 3 (32-bits)
  • 31:08 = 0x000000
  • 07:00 = RCE Address
  Header 2/3 (64-bits)
  • Trigger Timestamp

Then there are a variable number of MultiSamples which are the 6 samples plus location information which make up a waveform:
