- Abstract:
- The paper presents universal laboratory measurement system for evaluation of the impedance spectroscopy method based on multi-harmonic excitation signal. The system is mainly designed to optimise the method for impedance spectrum digital measurement dedicated to implement in low-cost portable instrument oriented for diagnostics of technical objects located in the field. Due to time constraints during field measurements, it is important to shorten acquisition time of impedance spectrum by using multi-harmonic excitation. Implementation of the method in the field-worthy instrument requires optimisation procedures in terms of hardware complexity and power consumption requirements minimisation. The results of simulation tests as well as experimental verification were presented.
