TSA Detrend tool (with variable time)

[dafemagu]

I am trying to use the TSA detrend tool on my recorded data (time and voltage). The problem is that my data was not acquired at regular time intervals. Particularly, a first set of data was acquired at a sampling rate of 1HZ, the second set of data at 10HZ, the third set of data at 1HZ ……..

Even I tried to introduce the data on the TSA detrend tool as an 2d-array, with first column time, but error 42423 occurred, Do you know how I could to introduce the time on my data so I can use this tool properly?

The tool works perfectly fine when I introduce only the voltage, but obviously the detrended output is incorrect.

What is "the TSA detrend tool"? IFAIK, There's no such think build into LabVIEW.

Is it a toolkit? A method? A Library? Something you made? Are there VIs?
