Hi All,
I've been using this feature since JMP 16, it's a real big saver in trying to churn out multiple magnitude vs. frequency graphs. I'm trying to sort out issues in my data, and was hoping for some scripting help, and request for features.
1) When I save my spectral data the period and frequency columns do not consider the time scale I used to make the time series graphs. So I am repeatedly making a new column that is Frequency/delta_time. (I verified this is valid by playing my bass guitar through my scope playing the A string.)
2) The Spectral Density Magnitudes seem orders of magnitude lower than my input data. From my understanding Spectral Density units should be the same as my input on JMP, whereas Spectral Density of Volts would be Volts^2/Hz?
3) Since I'm using this for vibration analysis what scripting would need to be done to also automatically convert my measured voltage into three columns of acceleration, velocity and displacement?
4) The nice feature in JMP 18 is that they all get automatically get saved into one big file, unfortunately it's not super clear as to which file is which, because it seems to lose part of the original file name in the combined file when making the Group in Save column.
Cheers and Many Thanks,
Ben
