Dear Elton,Can you help me send some illustrations about total harmonic analysis and SINAD in measurement studio for visual basic 6.0? E-mail address:Kelven.huai@philips.com

[kelven]

It is urgent!

Hi Kelven,

Unfortunately, I do not know much about total harmonic analysis and SINAD, so I can't offer much help with this question. I primarily answer general programming, .NET, UI, and Windows related questions. Hopefully someone else on the forum will be able to provide some assistance. Sorry I couldn't help and good luck with your project.

Hello Kelven,

I'm sorry, but Measurement Studio does not provide functionality for Total Harmonic Distortion or SINAD analysis. However, since these complex measurements are composed of more primitive measurements that Measurement Studio does provide (like auto power spectrum, FFT, etc.), you should be able to build these complex calculations.

A general description and example of how this functionality was built in LabVIEW can be found here:
