	Dynamic Signal Analyzer Grohoľ, Stanislav ; Ing. Miroslav Horáček, Ph.D., ÚPT AVČR Brno (referee) ; Zobač, Martin (advisor) The thesis deals with the two-port transmission measurement using self-made dynamic signal analyzer (DSA) and its associated problems. The DSA is based on National Instruments data acquisition card. In this work are provides basic analysis, for which the DSA can be used. Described are methods of two-port transmission measuring. Definitions concerning the creation of the DSA are described in detail. Listed are the kinds of stimuli and parameters of data acquisition cards. The practical part describes the properties of the selected data acquisition card for DSA and utility, created in MATLAB. In practical part are verified properties of individual stimulus and referred to the comparison with theoretical properties. Selected stimulus is used in a particular two-port measurement and the results are compared with theoretical model. Experimentally is determined the size of the dynamic range of the analyzer.

	Electron Beam Control and Diagnostics for Advanced Technologies Zobač, Martin ; Kolařík, Vladimír (referee) ; Průša, Stanislav (referee) ; Lencová, Bohumila (advisor) The thesis deals with problems of control and diagnostics of electron beam technological devices which use electron beam for localised intensive heating of a material. A brief description of the electron beam welder MEBW-60/2 is included; the author has participated on its development and implementation. Main topics are the analysis of deflection system properties and the measurement of current distribution of the beam (so-called beam profiles). Geometrical aberrations, hysteresis, stability and dynamics of a single-stage magnetic x-y deflection system are described. Suitable measurement procedures and correction methods are introduced. Methods of transverse and longitudinal beam profile acquisition is presented using successive sampling of the local current density of the beam by a modified Faraday cup. The data processing and evaluation of characteristic beam parameters are shown. The presented methods were verified by fourteen experiments using the electron beam welder. The methods have proven to be useful in practical evaluation of the device properties. Detailed record
