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.

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.

Laboratory equiptment for GPIB bus control interface
Ondrák, Jan ; Háze, Jiří (referee) ; Pavlík, Michal (advisor)
The project deals with a USB–GPIB converter, extended by two analog inputs with voltage range from -10 V to +10 V. The converter will be used in combination with the device EG&G Princeton Applied Research - Lock-in Amplifier 5208 and personal computer equipped with USB. The converter is controlled by PC via programmed application and will be able to control by the Lock-in Amplifier 5208 and also read the voltage on the converter analog inputs.

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.

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.
