timed sequence problem

hello!

 

I am currently working on a program that instructs a laser to lase and a PMT to read the number of counts of photons received. Attached please find the core sub VI program.

 

However, I do not really understand how the timed sequence works. The millisecond delay is supposed to be the delay between 2 laser pulses. Read in array is a sub vi that tells the array of PMT to read counts, and Read out array is a sub vi that reads the data from the PMT. Fire laser is a sub vi that instructs the laser to lase.

 

Could you kindly explain the sequence of events in this sub vi? In the main program, it is put in a big while loop, and there is a delay timer (Wait 20 ms). What would the delay between 2 laser pulse and that between 2 PMT readings?


Thank you so much for your kind help!!! Your generousity is highly appreciated!
