Peak detection

[chrlum47]

I'd like to find peak wavelength from my spectrometer output scan.

Does anybody have a peak detection VI compatible with LabVIEW 2018?

thank you

What package of LabVIEW do you have?

There is a Peak Detector VI built into LabVIEW.  But it requires you to have the Full Development System or higher.

A quick search (quick drop, on the diagram hit Strg-Space) often helps to find possible vis 😉

In that case, you should be able to use the Peak Detector VI that @RavensFan mentioned.

In the Palettes, look under Signal Processing>>Signal Operation VIs>>Peak Detector.

Or,

Because of my region/language, I would say Ctrl-Space, but it means the same thing. Press it, type "Peak Detector" (or even just "peak"), and press "Enter" to be able to place it.

(You actually don't even have to press "Enter", but if you haven't used Quick Drop before, I think it's easier to start with a traditional keyboard workflow.)

Does that give you what you need?

yes to all those who help me would peak detection using the VI you recommended was just what I needed thank you
