Control Software for RLC meter HIOKI 3532
Slovák, Martin ; Beneš, Petr (referee) ; Keprt, Jiří (advisor)
Aim of work gets up on questions and methods about measuring by RLC meter and realize control software for RLC meter HIOKI 3532. Theoretic part of work put mind to problems about impedance measuring, especially about means of their measuring. Next part deal with RLC meter HIOKI 3532 in particular to his properties, possibility of configuration and his communication by means of GPIB. Therefore next section surveys on the measuring systems, in accordance with standard GPIB. The main section is survey to control software for RLC meter HIOKI 3532 which is realize in the graphic programming language LabVIEW. The software made as an instrument to control and configuration of RLC meter parameters, which is needed to frequency response characteristic measuring and archiving. Work notes basic adumbration about software realization. And instruction for taking frequency response characteristic of measured item. Last part of the work contains from validation measure which took by the software.

Modelling of differential current amplifier
Polák, Josef ; Šotner, Roman (referee) ; Jeřábek, Jan (advisor)
The aim of my diploma thesis was programming of systems for measuring AC, DC and impedance measurements. Each measuring system measures selected characteristics of current amplifier with controllable amplification DACA_N. Control programs I have created in Agilent VEE Pro 9.2. The measured data are stored to executable files in MS Excel for further processing. With created measurement programs I made measurements of eight current amplifiers. The results of individual measurements I compiled into graphs and compared with each other circuit characteristics of amplifiers. Then there is described controlling and connection of current amplifier and its construction. At the end the diploma thesis describes amplifiers with the worst and the best measured circuit characteristics. The measured values show that the amplifier DACA_N with slight differences works by theoretical assumptions and measurement systems suggested by me work with no problem.

Automatic test setup for airborne radio-communication system R-863
Kropáček, Ondřej ; Špaček, Jiří (referee) ; Dřínovský, Jiří (advisor)
The aim of this thesis is design and realization of automatic test bench for parameters analysis of airborn radio-communication system R-863. Firstly we have taken up principles of the analysis properties of the radio system R-863. Then we proposed test bench for parameters analysis. In the next step we realize and integrate the digital control panel into the test bench. In harmony with the previous steps we have made program and software for the automatic test bench. Finally we make the user manual, which is easy to use.

Web interface for on-line administration of laboratory tasks
Belko, Jakub ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
The present work describes the current trends and e-learning methods using the Internet in the educational process on Czech and foreign universities. The main objective is to create a web interface for on-line administrations of laboratory tasks named "Laboratorě UETE". Practical work is focused on programming web applications and modules for management of instrumentation for laboratory protocols administration including implementation of the IP video cameras outputs and sensor atmospheric conditions. An integral part of this work is to create a module for simulation of physical quantities using commercially available software components based on client – server system.

Meaurement process automatization of deviations and stability of oscilators
Čermák, Jan ; Nováková Zachovalová, Věra (referee) ; Havlíková, Marie (advisor)
This Master´s thesis on a topic ,,Meaurement process automatization of deviations and stability of oscilators‘‘ describes methods for measuring the difference of time scales. Using this method, calculates the parameters of the oscillator, which is also describes in this work. Parameters of the oscillator means inning and stability. Describes is the procedure for calculating the uncertainties and their presentation in the final calibration sheet. This Master´s thesis also describes the practical measurement with this method in the Czech metrology institute in Brno. Measurement of the parameters of oscillator by the method of measurement of the difference of time scales is carried out automatically by computer. This Master´s thesis deals with the creation and development of new software and thus the automation of the entire task.

The V-mux test system
Morávek, Patrik ; Herman, Ivo (referee) ; Novotný, Vít (advisor)
An optical network technology is the network technology that meets given requirements for a fast and reliable long-distance information transmission. Optical fibres can offer undoubted features where other communication technologies are near their limits or stand in front of insurmountable problems. The intensive research of last years is focused on optical transmission features utilization in the optimal way. Especially an optical signal processing in active network devices without a need for electrical conversation is a topic of high interest. V-Mux is an optical network device that accomplishes above mentioned requirements for modern optical network devices. It is a device that multiplexes and drops an optical signal in its native light form into or from optical fibre. Basic micro electro-mechanical components, which the V-Mux is built from, are high end precise devices. The whole complex V-Mux has to meet strict rules and specifications as the components itself. That is why a control system has to be included in the production process to keep quality and right functionality. This diploma thesis is focused on a development of the testing system that will help in the automated control procedure in the V-Mux production. A brief introduction to optical network technologies and a description of the GPIB bus form a first part of the thesis. The next part focuses on the V-Mux itself and the proposal of the test station with its component description. The last part deals with a developing of the software for the V-Mux testboard and a user application that will be used for the test system initialization.
