DSL analyzer
Hála, David ; Číž, Radim (referee) ; Šilhavý, Pavel (advisor)
This bachelor thesis is devoted to the development of an application for signal analysis using xDSL technology. The first part of the thesis describes the basics of these tech- nologies and the theoretical assumptions that can be expected in later analysis. Also the parameters measured by the resulting application are explained. The second part of the thesis is devoted to the description of the procedure and solution of the practical part of the thesis - program development. Finally, in the last chapter of the thesis, the program was tested in laboratory conditions and graphs were constructed from the results.

Automation of measurement of disturbance influence on xDSL technologies
Röszler, Pavel ; Číž, Radim (referee) ; Šilhavý, Pavel (advisor)
This work focuses on interference of DSL transmission, measurement and testing with Spirent noise generator and injection unit. Deals with proposition of automated measurement of transmission bit rate dependency on wireline lenght and noise type and level. In theoretical part are described ADSL technology and noise types. Following part focuses on measurement setup and description of wireline simulator units E414 and 8234, gene- rator DLS-5800 a injection unit DLS-5410DC by Spirent company. Main part describes generator and injection unit control software and remote control commands, which are used for automated measurement. There are also described xDSL Measure tool software, which is using for automated measurement with wireline simulators and upgrade, which implements remote communication with generator a injection unit, for remote control and automatic changing noise types generated at the output.
