STM32 as an embedded processor is utilized as the control unit of the handheld oscilloscope, and the data is processed by the FPGA. Voltage signal is collected by probes, and then converted into digital signal after being amplified. Digital signal is showed on the TFT screen after the FIFO processing in FPGA and digital signal processing .The dual ADCs are used to convert analog signal into digital signal so as to double sampling rate, which is an effective and economic way to improve the performance of oscilloscope. At the same time, the figure displayed on the screen can be adjusted manually and provide the information of voltage and frequency. The test results show that the oscilloscope has very good performance.
