I'm sorry for the previous message. (I don't know how to delete it)
Anyway, I'm writing program which counts events for a certain period time.
For example, I want to count events for 1 second.
However I want to control the counting period at more accurate rate (not software timing)
I want to directly control the clock on the counter board.
How can I do that? Now I made my program using single-event counting vi.
Do I have to use gated one? I don't need time-resolved counting,
but I just need more accurate timing control.
Thank you for your replying
