Open full text 3 citations

Abstract

A kind of portable digital storage oscilloscope (DSO) is developed in this paper. It builds trigger, storage, measurement module for embedded system with programmable logic resource of FPGA chip. The external digital circuits of a digital oscilloscope is achieved. And it saves a lot of cost by implanting NIOS II soft-core processor as the control unit of the system in the FPGA. This system has the function of automatic frequency control (AFC) and automatic gain control (AGC), and it can measure the signal conveniently.
