JLab F250ADC

From New IAC Wiki
Jump to navigation Jump to search

JLab has built their own Flash ADC (called the F250)

It has a mini trigger connector which requires another VME board to convert from the standard lemo input to this mini input.

Addressing

JLab's F250 flash ADC will be used to measure the NaI output

Software Trigger

Initialize FADC for software trigger mode

Initialize the FADC so it will accept software triggers.

Notice FADC ID is 0 in Slot 4

define processing mode

int
faSetProcMode(int id, int pmode, unsigned int PL, unsigned int PTW,
	      unsigned int NSB, unsigned int NSA, unsigned int NP, int bank)


An example of this should be in one of the Readout lists, however, right now there are 3 viable processing modes (pmode =1,2 or 3)

pmode = 1  RAW Window mode: all samples within PTW are saved
pmode = 2  RAW Pulse mode: NSA+NSB+1 samples around a threshold crossing
                          are saved.
pmode = 3  Integral pulse mode: NSA+NSB+1 samples are summed and the sum
          along with the timestmp for the threshold crossing are saved.
