Abstract
In this paper the method for fast impedancespectroscopy of technical objects with very high impedance(|Zx| ≥ 1 GΩ) is evaluated by means of simulation and practicalexperiment. The method is based on excitation of an object, witha square pulse and measurements of voltage and currentresponses with DAQ card. The object impedance spectrum isobtained with use of continuous Fourier transform. Someimprovements of the method concerned on sampling momentsoptimization are discussed. The method is evaluated in Matlab bymeans of simulation and then practically verified on constructedlaboratory impedance spectroscopy measurement system.
