Read FFT channels with Dwdatareader Python

Hi!

Is it possible to read Dewesoft calculated FFT with dwdatareader in Python?

It works just fine for me to read the time signal, but not FFT.

Hi Benji,

It is possible. Do you have datafile and an example of what you are intending to read? You can send it to us in Private discussion.

Best regards

Dear Benji,

we have made a quick test with simulated channels and tried reading the FFT data with Python.

The data is available if FFT analysis in channel setup is used. If you store the data with FFT preview the Python script cannot access the data.

Below is a picture of the example:

I hope the above is useful to you. If you require a more specific explanation or help we would need a short data file, so we could have a better look into the project.

Best Regards.

Sorry! I can't open the picture you have posted.

Dear Benji,

I have attached the picture. Please let us know if this works.

Thanks! I can see now the attached file :)

Is it possible for you to share your code?

I can read the FFT channel now, but still, it's not correct.

Dear Benji,

attached you can find the DWData reader examples. These scripts were used to open the FFT data.

The scripts are in the ''Win32&64 Python'' folder.

Please let me know if you have any questions.

Best Regards.

Thanks!

Is there any instruction on how to install the DWDataReader package for Python?

I used Pip, but I got the 0.13.1 version of DWDataReader.

Dear Benji,

you do not need to install the packages. Just download the package and run the script.

Best Regards.
