Hi all labview user ! i'm just a new user of Labview and i have a problem about finding rise time and fall time of Full wave lightning impulse !! any idea about this problem when front panel result shown NaN while i try to find on Negative lightning impulse . sorry my english not too good.
best regard ,thanks !
Solved! Go to Solution.

here is a Q&D solution avoiding the express vi (couldn't load your vi anyway ;)) and using the pulse measurement and trigger vis provided....
no time for clean up 😄 ups .. slope ... your homework 😄 😄

brother can i ask u 1 more question ? how can i detect time of chopping impulse waveform ( Index or value ) ? can u suggest me some VI or some technic thanks .

Some basics from school: Derivates help to find characteristic points.
Other handy tools:
low pass filter
high pass filter
FIR filter ..
But the best: How do you find them?
Draw it , wire it , run it 😄
Post some real data, and your vi ...

here brother !! but i still can't fine that chopping value

Is real data and vi so easy to misunderstand??

vi and I don’t know which vi I should use to detect that breakdown point (voltage) !!
Many thanks
