LOW COST IMPEDANCE ANALYSER FOR DIAGNOSTICS OF NON-ELECTRICAL OBJECTS
Jerzy Hoja, Grzegorz Lentka
Abstract:
The paper presents an impedance analyzer designed for impedance spectroscopy of non-electrical objects described by multi-element electrical circuits. The analyser measures a modulus and a phase or a real and a imaginary part of impedance in a wide frequency range 100 µHz - 100 kHz. The special feature of the analyser is ability of measuring very high impedance (|Z>sub>x| ≤ 10 GΩ). The method based on discrete Fourier transformation has been used to determine the orthogonal components of measuring signals. The analyser has been built as virtual instrument using DSP processor. This assures high flexibility and low price, because adaptation of the analyser to selected object requires only modification of PC software.
