Hi,
I am using an MCP detector which detects molecular ions. For each ion falling on the detector it generates a bunch of electrons by its mechanism. Due to that it generates pulses which goes as input of a constant fraction discriminator with pulse amplifier. This pulse amplifier gives me LVTTL signal as output. Each pulse in this LVTTL signal corresponds to one electron. My aim is to count the LVTTL pulses that occur per second which will let me know the number of electrons collected on an anode plate per second.
I have PCIe-6612 and PCIe-6323 with BNC-2121 and BNC-2090A terminal block. Is it possible to use any of these two as my counter which will show me the counts/sec, that means counts will be reset after showing the value at every second. Finally I want to take those values of counts/sec to plot a graph. If it's possible please explain the hardware connections and shortly the steps of LabVIEW code also.
I am a new user of LabVIEW and trying to learn it. After reading the manuals of PCIe-6612 and BNC-2121, I connected the LVTTL signal to the source (pfi-39) of counter zero, and tried edge count. Counter couldn't detect the input signal and so it didn't start to count. One thing I noticed that counter zero can detect this input signal if I connect it to pfi-37 (counter 0 aux) then it starts counting. Could anyone please clarify this. I am using LabVIEW 2018 version.
Thanking you in advance.
