| Abstract: | An arbitrary waveform generator was developed by CPU control to generate waves in time or frequency domain input method, which could compatibly work in intelligent and virtual mode, in which Delphi 7.0 was used for upper computer work' s menu, USB 1.1 for instrument communication interface, FPGA for digital platform, LCD for figures and menu interface when intelligent mode, waves parameters can be adjusted online step-by-step, the development result showed the idea and method were effective, specific FPGA design methods, software flow, signal input method were introduced in the paper. How to design a new-style software by which arbitrary waveform could be produced and controlled based on Delphi 7.0 in the Windows was introduced in this article. Beside shapes of general waves, a method for collecting data, from arbitrary waveform, superposition of frequency domain producer, correspondence connects, and the realizing principle & design method of the transition from frequency domain to time-domain were especially discussed. Experimental results show that this software has it's facile interface and could be conveniently used, flexibly measured and transplanted, the function of the alternation between user and the DDS arbitrary was well realized. Lastly, the validity of the design method was well proved by experiments. |
