Hi Hai, Ed, Quick question: I initialize the board in the pulse raw data faSetProcMode(FA_SLOT,2,170,50,10,15,3,0), i.e., Nsb = 10 Nsa = 15 How many samples should i see in data ? I am getting 24 samples for pulses that crosses a threshold in the middle of the readout window. Is it correct ? Thanks, Alex
