Modern FFT analyzers and complex pink noise generators are powerful, but they shouldn't replace the fundamentals. Fixed-frequency testing isn't just a relic of analog meters; it is a targeted stress test that ensures reliability. festfrequenzprüfung

Fixed frequency testing has one major pitfall: . Unlike a sweep that spreads energy across a spectrum, a Festfrequenzprüfung pours energy into one structural mode. Without careful amplitude control, localized heating can change the material's Young's modulus, shifting the natural frequency during the test —invalidating the results. festfrequenzprüfung

Next time you see an unexplained harmonic in your FFT, don't just sweep past it. Lock on. Test fixed. Find the truth. festfrequenzprüfung
