Hello, I would like to measure the frequency of a signal over time like drawn in the attached draft. Is this with Diadem possible? I could not find a function for that. The frequency to be measured is expected in a specific range (40-80 Hz). But the signal has noise (Much higher frequency), so if only the time between zero crossing is measured, this will give no proper result (Maybe there is an option to discard higher frequencies?) Thanks very much for answers!

Hi Tooly, I posted the beta version that works with DIAdem 2015 to our outgoing ftp site, you can get from here for the next couple of days before it is automatically removed: "ftp.ni.com/outgoing/Time Frequency Order Analysis 2015 Beta.zip" The RPM Calculation has filtering/smoothing options on both the Y and X axes.

Solved!

Please can you check in the about box, installation whether there is Professional Edition displayed?
