A commissioning engineer walks onto a turbine deck with eight accelerometers, a laptop, and no way to run cables from the bearing housings to a control room without crossing a walkway. This is the mo...

An engine bearing begins to degrade long before an alarm sounds. The first sign is often a small change in vibration: a new spectral peak, a slight phase shift, or a slow increase in broadband noise....

Measurement Science — Instrumentation A close look at why FFT-based architecture gives the Dynamic Signal Analyzer a decisive edge at low frequencies — and where the traditional spectrum analyzer sti...

A vibration shaker works by converting electrical energy into controlled mechanical motion, using either an electrodynamic coil-and-magnet system or a mechanical exciter to push a moving table or arm...

A modal shaker exciter is an electromechanical device that converts an electrical drive signal into a controlled mechanical force, applied directly to a test structure so engineers can measure its na...
