Piezoelectric resonances measuring system operating in a novel lock-on-resonance mode

A complete system, USB 2.0 powered “virtual instrument”, that excites and measures all physically existing resonances for all inherent vibrational modes in any type piezoelement is described. Measurements are performed after locking on the chosen resonance by a novel frequency neutral loop. Intrinsically detailed scanning by phase (in a deviation manner from resonance center) results in huge amount of precise data whose extensive processing determines the exact values of all resonance parameters.
