Climatic tests of the calibrator 9010
Plánka, Mikuláš ; Sitta, Michal (referee) ; Šedivá, Soňa (advisor)
This bachelor thesis deals with climatic testing of Calibrator 9010. The content of this work is a theoretical analysis of climatic tests. Furthermore, the properties of the Caliber program are described here. Caliber program in this work is used for automated measurement. The next chapter in the work is a description of the properties and functions of the Calibrator 9010. In the practical part of the work, the points of the measurement itself are proposed. Based on the design of points, a procedure is created in the Caliber program. Procedure is used to measure data. The measured results in the work were evaluated.

Optimization of AC signal voltage amplifier
Vaculík, Lukáš ; Sitta, Michal (referee) ; Šedivá, Soňa (advisor)
The Bachelor thesis deals with the analysis of the voltage amplifier and with simulation of its behavior using program LTspice. The basics for working in this simulation program are also described. The content of thesis is also a measurement of the actual implementation of the amplifier for comparison with the performed simulations. Subsequently, there are outlined possible solutions how to optimize the scheme in order to achieve the best possible results in the monitored parameters, especially the distortion and amplitude of the output signal in the thesis. The scheme was presented by Meatest, s.r.o., where the amplifier is part of a multifunction calibrator. Theoretical part, which serves as an introduction to the issue, describes the components and introduces important concepts, is also included in the thesis.

Automatic control of the high-resistance resistor decade in calibrator 9010
Bilík, Petr ; Sitta, Michal (referee) ; Šedivá, Soňa (advisor)
This bachelor thesis deals with automatic calibration of high-voltage resistence decade of calibrator 9010. The theoretical part deals with multifunctional calibrator 9010 developed by Meatest company, mainly with its high-voltage resistance decade. The other part of this work deals with Caliber. This is program for calibration of instruments. List of methods for determination of resistance decade and equations for device errors and uncertainty of measurement is included. The procedure of calibration high-voltage resistance decade is the result of the practical part. Output protocol from Caliber points to functionality of decade calibrator 9010.

Wheeled-drive Robot Control
Sitta, Michal ; Veselý, Miloš (referee) ; Žalud, Luděk (advisor)
The aim of this thesis is to describe the electronics of autonomus outdoor robot called TIM2. TIM2 is a group project and only a part of the project is presented. First part this work is about chasses common used in robotics. Detailed description of each type of module used is described in this work. There is also described communication protocol. A controllers for front and rear axle are also described. One part of this work is measurement, it contains electronics characteristic of modules and measurement to describe quality of motor controllers. Last part of the document is about communication between modules and impact on the robot functionality in the case of failure of a module. Enclosure provides complete circuit diagrams, printed circuit boards, planting plans, lists of components for all designed modules.
