The measurement of transducer characteristics of piezoelectric devices is a prerequisite for the correct use of the device. For piezoelectric devices, the main parameters can be obtained through a transducer characteristic analyzer, including resonance frequency Fs, anti resonance frequency Fp, half power points F1 and F2, maximum admittance Gmax, static capacitance C0, dynamic reactance R1, dynamic capacitance C1, dynamic inductance L1, free capacitance CT, free dielectric constant, mechanical quality factor Qm, electromechanical coupling coefficient Keff, Kp, K31, K33, Etc, And five characteristic curves of piezoelectric devices can be drawn (admittance characteristic diagram, transducer characteristic diagram, admittance polar coordinate diagram, transducer characteristic polar coordinate diagram, logarithmic coordinate diagram).
