Drivers for optical spectral analyzer.
Fišer, Michal ; Pikula, Stanislav (referee) ; Mancl, Vlastimil (advisor)
This bachelor thesis describes the application for the control of the optical spectrum analyzer Bristol Instruments 771B-NIR. The purpose of the application is to measure the spectrum of optical signal and wavelength. Theoretical knowledge of wavelength and spectrum measurement and the optical spectral analyzers are summarized in the theoretical part. The practical part focused on the realization of measurement application and library of functions that were created in the LabVIEW environment and the SCPI standard commands are used to control the instrument. Both the application and the library of functions are inspired by the factory-supplied NuVIEW interface.

Computer application for measuring parameters of network
Kolmačka, Tomáš ; Urban, František (referee) ; Grenar, David (advisor)
This bachelor’s thesis deals with the basic theory of network architecture TCP/IP which is used in practice and sets out the key parameters for data services and multimedia services using these networks. The thesis mainly deals with the methodology of measuring individual parameters and analyzes various methods of measurement and the accuracy of these methods. In the practical part of the bachelor's thesis a client-server mode application called Network Meter was programmed. This application allows the measurement of selected parameters between client and server using transport protocols TCP and UDP. When using TCP, the application can measure delay, data upload speed and data download speed. When using the second transport protocol, namely UDP, the application can measure jitter and packet loss. With the measuring application Network Meter test measurements were performed in the prepared home network. In the same network measurements were made using jPerf to compare the created application with other applications. In the comparison measurement download speed was measured.
