How to get the time crossing from amplitude of a signal by LabVIEW

Question

I am a labview new starter.

Here is my problem,I am working on a data processing LabVIEW program,now I use Threshold Detector VI to get the signals which have crossing the threshold,and I have the indices of these signals.but the indices are related to the amplitude of the signals,what I want is the time crossings of these signals.

What can I do?

Thank you very much!

You can use Get Waveform Time Array to get an array of timestamps, then use your threshold indices to select from the timestamp array.
