Study On The Hardware Platform Of Universal Electronic Test Instrument Based On Embedded System

The Embeded System is a kind of computer system with special functions. When it is integrated with communication and network technology, it will enhance the ability and intelligent of instruments and devices'network and communication. With the constantly developing of the information technology and increasing of the requirement of users, the Embedded System is entering into all kinds of fields of national product gradually and used extensively .The development of the Test & Control instrument and device based on the embedded system will enforce the ability of communication, intercommunion, data procession and so on, at same time it can extent the application.This paper provides a solution and a new platform of universal electronic test and measure instruments based on 32bit embedded processor. The platform is based on S3C2410 ARM Processor, with various peripheral resources. Include 2410 core-system; interactive client equipments based on hi resolution touch-screen; mass memory card or HDD interface; USB-HOST port and USB-DEVICE ports; 100Mbps Fast-Ethernet port; VGA interface; Audio interface etc. The peripheral resources can meet the requirement of interactive operation, storage and communication for most instruments. This paper focuses on the hardware realization of the platform.This paper discusses the interface between 2410 system and module instrument. With different module instrument's plug in, the platform functionally as corresponding instrument. And we designed several module instruments. Such as 61/2-digit voltage meter, impendent analyzer, digital storage oscilloscope, capacitor meter, VXI interface module,GPIB module etc. And some of them are in production.
