Falling time in Transition Measurement

[ElPau]

I am trying to get the time when the signal falls.

Transition duration seems to be ok but the start and the end time are always 3.74G and do not know the reason.

For a triangle signal it is working but not for the waveform attached in the VI.

Thanks!

Set the display format for start/end time to "Absolute time" with a reasonable formatting, like "YY-MM-DD HH:MM:SS.uuu" to learn about the meaning of "3.47G"…

(To verify the result of that formatting operation you could right-click the X scale of the graph and deselect that "ignore timestamp on X axis" option!)

Thank you GerdW for the response,

So if I undertand well, the starting and ending time is a huge number because it is taking the absolute time from the beginning.

So what I did was to format the t0 from the waveform into a double precision number, then substract the start time i got from the Transition Measurement VI to the t0 and voila!

Thanks!
