record rise-fall edge of pwm SIGNAL

[Lily3000]

Hello, hopefully someone can help me. I am trying to record rise, fall and period of pwm signal. I have this vi that is attached. if I place graph after NI scope multi fetch signal i see my PWM but nothing is recorded into a csv file and get waveform component shows  when I highlight execution to see what is going on. What is wrong with my vi? Thank you

Hi Lily,

are you sure about your reference levels with unit percent?

Using levels of 3%, 1.65% and 0.33% seems rather uncommon to me…

My bad, it should be absolute. But the result is the same

Can you attach your VI with some measurement data so we can analyze too?

(We don't have your scope and we don't have your DUT to measure their signals.)
