how to get spectral map from measurement??

[alfredo_2k2]

dear all,

i built a data aqcuisition by using LabVIEW 7.1, and now it can be used to analyze dynamic signals such as waveform, linear and power spectrum. But i still cannot find algorithm to return spectral map from measurement... i will use frequency axis, vibration level axis, and also RPM axis... if any of you understand how to make it please give some solution or example code...i will appreciate it..

Thanks so much...

Hi Alfredo,

The application you're describing sounds like something that our Order Analysis Toolkit might be useful for.  You can find more information about using this toolkit in our Developer's Zone at this link.  If you just need to create an intensity chart (two positional axes and one intensity value for the point represented by a color), we have that feature built into LabVIEW without this toolkit as well.  We have the Intensity Graph indicator which accepts a 2-dimensional array of values, these can easily be your three axes.  You will need to build the array from your three input sources and know the correlation between them.
