Abstract

Abstract: This paper discusses the chief techniques and design principles of an embedded digital storage oscilloscope based on PXA 270, using FPGA as logic controller cell. The data acquisition partition consists of pre-process circuit, A/D converter, on-board memories, and control circuit integrated in FPGA. In the PB and EVC development environment, developers realized the part of embedded software. Actual test showed that the highest real-time sampling rate of the oscilloscope is up to 1GHz/s, which has achieved the desired design requirements.
