FADC data structure
SAMPLE Mode (1)
When the FADC is read out in sample mode a CODA bank called "0x250" is used to store the data arrays representing the time based samples of the FADC input. Below is an illustration of the structure using xcefdmp.
Event ID bank
The physics event type header is written as a "GO event"
