Revision as of 21:20, 18 April 2011
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.
faInit(0xbb0000,0,0,0)
-> faInit(0xbb0000,0,0,0) Initialized FADC 0 Slot # 4 at address 0x90bb0000 faInit: Enabling FADC Internal Clock, and Software Triggers (Soft Sync Reset) value = 0 = 0x0
- Notice FADC ID is 0 in Slot 4 (the slots are number according to their location from the left most slot in the crate which starts counting at 1)
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.
PL = latency = PL=20 => 200 nsec; time delay to record measurements after trigger is received and time window begins
PTW= 20 => 80 nsecPulse Time width = time interval window for measurements
Assuming the Clock is 250 MHz => clock pulse widths are 4 nsec
faSetProcMode(4,1,40,38,3,6,1,0)
