Input value range selection (Extract portion of Signal)

[Nusnus]

Hi Guys,

Im trying to select a value range from a signal. i can fix the starting point value which is -0.2 but i coudnt set the ending value range which is 0.2.

I only managed to set the length in number of sample but not in unit value. Is there any way so set the range portion from -0.2 to 0.2?

Here, i also attached the vi and data file. (Run, dont use Run Continously)

Hi Nus²,

no need for ExpressVIs for such a simple task:

Now you can access the X data array easily and use array functions (like Threshold1DArray) to find the indexes of your desired range in the array. You will do this twice: first from the start, then from the end. With those two indices found you can easily create subsets of your array data - well, the needed function is named ArraySubset…

Btw. not everybody here is able to use 7zip so you better attach VIs either directly as VI or use standard ZIP format!
