PCI6602 to detect TTL output from single photon counter

[Frankie Godfrey]

Dear all,

I am learning how to use Labview.

Here is the system I try to set up.

1.   Single photon counting module, 2.5v TTL output, 20MHz light source

2. BNC-2121 block

3. PCI6602

4. Labview 7.0, NI-DAQmx

The aim of this system is to counts the number of the detected photons from the light source.

I have problem to start this task. Can you guys help to creat a sample which i can start from?  

Your help will be greatly appreciated.

Hi Frankie,

I would suggest using the NI-DAQmx counter shipping examples to get started.  The Count Digital Events VI would be a good starting point. 
You can open it through:

Hope this helps!
