The Design Of Portable Digital Storage Oscilloscope Table Based On ARM

Due to the rapid development of science and technology and measurement technology, the traditional analog oscilloscope cannot meet the needs of the r&d designers and engineers. And on the basis of the traditional analog oscilloscope research and development of the digital storage oscilloscope is more popular with engineers, digital storage oscilloscope, first of all, to high-speed sampling of analog signals were collected, and then to obtain the corresponding digital signals stored data flow, adopting digital signal processing technology of digital signal processing and operation, and the processing result display.This topic of the portable digital storage oscilloscope table on the basis of the digital storage oscilloscope designed, integrated digital multimeter, volume small, function is rich, can be very good to adapt to the dangerous environment and outdoor operation, widely used in various fields of engineering and design. Digital storage oscilloscope inherits the traditional analog oscilloscope the functions and characteristics, such as:transient signals of high-speed real-time capture, parameter calculation speed, high precision, data storage depth is big, can according to the characteristics of the measured signal automatic measurement, etc.Handheld digital storage oscillograph of the completion of this topic is the design of the table, the operating system core plate applied to the underlying hardware, the overall design of the whole system is ARM+FPGA+frame structure of the ADC, and S3C2410operating system platform. S3C2410hardware interface circuit design, mainly complete the USB interface circuit design, serial interface circuit design, so design of interface circuit, LCD display interface circuit design, etc. S3C2410operating system design, mainly to complete the BootLoader transplantation and modification, S3C2410operating system kernel, customized, LCD display driver of transplantation and modification, etc.This topic mainly completed the design of the following four parts:hardware platform design of interface circuit, data acquisition and storage circuit design, the system main control circuit design, digital multimeter module design. In this topic design process mainly completed the following content.
