This thesis describes the design of portable multi-purpose measuring device with Microcontrollers from Microchip running on battery power, for displaying the measured signal uses a graphical LCD with a resolution of 240x128. The device is equipped with an oscilloscope and multimeter with auto range.

This diploma thesis deals with the creation of the Virtual Measuring Instruments web application. This tool mainly enables us to simulate the real measuring instruments widely used in the laboratories of FEEC BUT. It is intended to serve students for initial acquaintance with specific devices. The theoretical part is focused on the research into the web applications programming and suitable programming languages to implement the proposed application are selected. Furthermore, the specific virtualized devices are described. The result of the experimental part consists in creating a universal application interface to extend the proposed application with other devices. Finally, the specific tests of the developed platform are presented.

The traditional radiation testing of space electronics has been used for more than fifty years to support the radiation hardness assurance. Its typical goal is to ensure reliable operation of the spacecraft in the harsh environment of space. This PhD research looks into the radiation testing from a different perspective; the goal is to develop radiation testing methods that are focused not only on the reliability of the components but also on a continuous radiation-induced degradation of their performance. Such data are crucial for the understanding of the impact of radiation on the measurement uncertainty of data acquisition systems onboard research space missions.
