3 Impedance Response

Understanding the impedance response of the piezo component and the associated system is essential for effective utilization of piezo-based loads. It is advisable to measure the impedance response ranging from the individual component to the complete system throughout the critical assembly phases.

The impedance response described in the document is measured by an impedance analyzer (Model: Agilent/HP 4294A). A similar tool can be used.
