Funktions of Spectrum Analyser N1996A-503
Šoukal, David ; Šedivá, Soňa (referee) ; Havlíková, Marie (advisor)
The theme of this diploma work is to introduce spectrum analzyer Agilent CSA N1996A to readers. In the work there are explained in detail all measuring functions of this machine, there are also mentioned all engineering characteristics and described all operating elements of this machine. In the diploma work is also mentioned the basice division of spectrum analyzers and their principles of activity. In the pracical part there are proposed the measurement assignments for hearers of subject MEMT, where is the possibility to use already mentioned spectrum analyzer. Including of the assignments there are also theoretical analysis of each assignment, their diagrams of wiring, practical metering and interpretation of results.

Operation of a distribution system with resistance welders
Zelený, Miroslav ; Šlezingr, Jan (referee) ; Drápela, Jiří (advisor)
This Diploma thesis deals with assessment of the influence of two fundamental types of resistance welders operation on chosen power quality parameters at the point of common coupling (PCC) of the power network. The assessed parameters of power quality are the total harmonic distortion of the supply voltage, asymmetry of the supply voltage and the level of short term flicker at the point of common coupling. The assessment is based on the comparison of the results of computer simulations done in PSCad 4.2.0 with the requirements of technical standards. The outcome of this thesis is the determination of allowable limits for physical and operation parameters for the general arrangement of a power distribution network and a resistance welder that should guarantee the power quality compliance.
