I am measuring a simple cantilever system with a 10Hz natural frequency. The Spring experiment raw data clearly shows a 0.1-second period and the autocorrelation plot also indicates a 0.1-second period. But, the results, autocorrelation, and resonance tabs display a 0.2-second period and 5Hz frequency. Is there a bug or something I am missing in using the tool? The Acceleration Spectrum experiment correctly identifies the 10-Hz frequency for the same system and I have confirmed with other utilities.
