GUI for impedance measurement automation on Agilent 4294A
Dejdar, Petr ; Jeřábek, Jan (referee) ; Hanák, Pavel (advisor)
The goal of the bachelor thesis is to develop a control software for Agilent 4294A impedance analyser. Text of the theoretical section explains the dataflow of GPIB interface, basics of National Instruments LabView enviroment and the description of Agilent 4294A and its drivers for LabView. The function of the control software is a transfer of data from analyser, its conversion into Microsoft Excel .xlsx format + receiving screenshot in .png format from the analyser’s display. There are described all of subroutines contains setting and reading analyzers setting in this thesis. The conclusion sums up possible control software variation in regard to its complexity.

The Hefaistos System
Mancl, Vlastimil ; Beneš, Petr (referee) ; Pikula, Stanislav (advisor)
This master's thesis describes functionality and principle of the Hefaistos measurement system, which is fully automated and modular. Its purpose is to measure frequency responses of materials and its temperature dependence. The thesis describes all the necessary parts of the modular measurement system. Main part of this system is the control application programmed in LabVIEW software environment. Another necessary parts are impedance analyzers for acquiring frequency dependencies and heating chambers for heating measured materials. The control application ensures hardware synchronization between impedance analyzers and heating chambers. Together they create the Hefaistos system. Modularity of the system means that a user may choose which instrument combination will be used. The system offers choice between three impedance analyzers Agilent 4294A, Wayne Kerr 6520B and HIOKI 3532 LCR Hi-Tester and two heating chambers AOIP GEMINI 700 LRI and AOIP HYPERION. Possibilities of the Hefaistos system are demonstrated on the results of an example measurement.

The Hefaistos System
Mancl, Vlastimil
This paper describes functionality and principle of Hefaistos system. This system is fully automated and modular. Its purpose is for measurement of frequency responses of materials and its temperature dependence. Article describes all of the parts of modular measurement system, which main part is control application, programmed in LabVIEW software enviroment. Application is used for synchronization of hardware i.e. synchronization of frequency analyzer with heating chamber. Final aplication is user friendly and offers frequncy measurement with or without heating chamber. Possibilities of Hefaistos system are demonstrated on results of an example measurement.
