This thesis targets on design of portable device for impedance measurement. Theoretical knowledge related to the construction of a portable impedance analyzer is summarized in a separate chapter. This section also compares some commercially available impedance analyzers. In addition, this thesis contains a description of the principle of operation of the impedance analyzer, which is divided into individual function blocks and supplemented by control circuits. A large part of the work focuses on the design of the analog measurement circuit, where suitable measuring methods are also presented. The functionality of the analog blocks of the device was verified by circuit simulation in the PSpice program and by experimental tests. Selection of some components is mentioned in the relevant chapters, where the essential parameters from datasheets are listed. The output of the work deals with a designed prototype of the device, which was tested. Based on the findings some modifications of the device were proposed for practical usability. The attachment of the thesis contains final version of designed printed circuit board.
