Hello,
I would like to calculate a global weighted acceleration value from spectrum.
From time series, I apply a Data window (hanning) and then a FFT (Real FFT of a real Signal). I try to apply a weighting (block Measurement weighting) with" a weighted by table of reference points"... but I don't manage to create a correct table of reference points (file .dpf with my coefficient). I understood the structure file is the following :
INTERPOLATION
One channel
2
8192
<EOF>
But I have an error message when I start my measurement (Incorrect coefficient file). Could you please indicate me how can I do ? Could you send me an .dpf example file ? For information, my FFT has 8192 lines.
In advance, thank you very much.
Best regards.
Florent

Blocks entirely filled with values equal to 1.0 are weighted by the shown reference point file ( >>> picture).
