| Abstract: | This digital oscillograph used FPGA and ARM9 (S3C2410) as its core chip, including channel introduction process, trigger controller, data sampling, data processing, waveform display and operating panel. It not only has the function of real-time sampling, but also has the function of real time sampling and pre-trigger control. It use LCD and touch screen to display. Through the communicate between FPGA and ARM9, the frequency and rate can be displayed on LCD800 ± 480. The system applied modularization design method and used manifold tools of EDA, which make the design more efficient. |
