Abstract

Impedance analysis is very much useful in finding the characteristics of an electrical system and also helps to find equivalent circuit of different electrical devices including transducers like ultrasound transducers, sensors etc. In this work an impedance analyzer is implemented based on auto balancing bridge for finding the characteristics of ultrasound transducer. The signals for impedance characterization is generated and acquired by using National Instruments function generator NI PXI 5450 and scope NI PXI 5154. LabVIEW software is used for calculation of impedances. Using LabVIEW based Impedance Analyzer we can analyze impedances of a device upto a frequency level of 20MHz.
