Hello,
I want to trigger a channel from an external negative source. This will be a negative pulse. I'm using the NI-6351. It has an APFI0 analog trigger.
I've made the attached program but I don't understand why I have to use the "start digital edge" trigger to use it.
What's more, the signal isn't even synchronized with the trigger signal ??? cf image: the green curve shift... the yellow curve is the trigger signal.
Do you have any explanations or ideas?
thank you for your help
