Hi Serenity ,I ’m luiart.
First of all thanks for the program.
I understand that I shouldn’t send messages only to you but I’ve seen that you can help me very much.
I’ d like to have your opinion about this problem, if it’s possible: I hope so.
I’ve an optical transducer to take some reflective targets: there are 80 targets in a lap of 6550 metres. The transducer generates a square wave every time it sees a target. I send this square wave to the counter of my daq-board and it measures the period, than the frequency . I have a constant frequency , but the counter measures a not-constant frequency: the difference between two frequencies is always the same 0.28ms or a multiple of it.
What is it u
p to? Does it depend on the delay of my transducers? Does it depend on my program? Have you ever seen something like this?
I send you the file with the frequencies that I have acquired. I hope that you can help me.
Thanks VERY MUCH.
