An Embedded Virtual Digital Storage Oscilloscope with 1GSPS

Zhiqiang He, Zeng Wenxian, Jianke Li

Abstract

This paper discusses the chief techniques and design principles of an embedded virtual digital storage oscilloscope, which have two working mode: oscilloscope and data acquisition. The instrument consists of pre-process circuit, A/D converter, on-board memories, high-speed clock generator and control circuit integrated in FPGA. It can concatenate embedded CPU main board through PC/104 bus, and also can achieve 8-bit resolution allowing up to 1GHz sampling rate with 256KByte/channel on-board real-time memory.
