How can I perform a Start AND Stop Trigger on my PCI-4474

[Kimberly]

Triggering is relatively new to me. The problem I am having is that I need to measure the time that a signal is high. I would like acquisition to start on the rising edge of my trigger and end on the falling edge. Any help would be greatly appreciated. I am using LabVIEW 6.1 and Win2000 OS.

Check out the example that I have attached below. You'll probably want to set the pretrigger samples to the minimum value of 2.

Remember that there is a 38 sample delay on the analog input of the 4474 due to the delta sigma converter.

Hope this helps,
Jack A.
