Function generator with direct digital synthesis
Gál, Radek ; Prokopec, Jan (referee) ; Frýza, Tomáš (advisor)
This bachelor’s thesis describes the design and construction of function generator, which is based on an integrated circuit of a direct digital synthesis. The device has two outputs; first generates harmonic or triangular wave and second generates square wave. Adjustment of output signal is enable with using the buttons, the incremental rotation sensor and potentiometer and displaying by using the LCD display. Generator allows adjust output frequency in range from 1 Hz up to 10 MHz with 1 Hz step size, output voltage smoothly 0 – 10 V peak-peak or using -20 dB attenuator and dc-offset in range from -5 V to +5 V. Device has RS232 interface for connect with the PC.

Virtual oscilloscope
Hoferková, Kateřina ; Pikula, Stanislav (referee) ; Šedivá, Soňa (advisor)
This thesis is focused on the design and implementation of a virtual oscilloscope used primarily for study purposes. The virtual oscilloscope is created in LabVIEW environment. The application also includes a function generator with two outputs. The theoretical part of the thesis is focused on the analysis of function generator and oscilloscope, and also describes the LabVIEW environment and its possibilities for creating a virtual measuring instrument. The practical part of the thesis describes creating of a two-channel virtual oscilloscope, which is inspired by the Siglent SDS1000X series oscilloscope. The thesis also includes two laboratory tasks prepared for this virtual oscilloscope.

Instrument driver for two-channel waveform generator Aim-TTi TG501xA series
Opravil, Michal ; Klusáček, Stanislav (referee) ; Čala, Martin (advisor)
The bachelor thesis deals with designing and describing of instrument driver for generator Aim-TTi TG501xA series in LabVIEW development environment. In the thesis is defined the structure and requirements for creating of instrument driver for Aim-TTi TG5012A generator. Therein are also mentioned the parameters and advantages of the generator. To meet the requirements for the instrument driver the functions were defined, thereby generator may be controlled over USB or LAN. The other supplied functions are determined to generate all available signals and set their parameters. The validity of parameters set are examined by the function for monitoring of set-up that reads the data from error register of the generator and verifies the correctness of the adjustment of parameters. All functions uses the NI VISA libraries containing the functions for communication and functions providing read and write support for the device. All created functions were tested on generator TG5012A communicating via USB and LAN. For better comprehension, there is a set of examples given demonstrating the involvement and applicability of each function.

Function Generator with the Android Operating System
Neradilková, Aneta ; Čmiel, Vratislav (referee) ; Sekora, Jiří (advisor)
Function generators are equipments that generate a wide range of waveforms. This bachelor’s thesis introduces the function generator and Arduino platform. On the basis of familiarity with the function generator and the Arduino platform is designed proposal generator using Arduino kit and draft flowchart for generating four waveforms. This proposal is implemented and describes the different parts of the generator, hardware and software. The functionality of the generator is tested using an oscilloscope.

Laboratory waveform generator based on DDS
Kret, Tomáš ; Povalač, Aleš (referee) ; Šebesta, Jiří (advisor)
The project concerns about design of function generator based on direct digital synthesis, its software and hardware realisation. It solves generating functions depended on time like sine, triangle and square with variable duty cycle, burst and other functions of frequency sweep, FM and PWM modulation. Next goal is to display user interface on graphic LCD display and to control microcontroler pheripheries of AVR.
