A digital storage oscilloscope module in automatic test equipment was designed based on PIX bus. The field programmable gate array (FPGA) is used as the logic control unit. The circuit of high speed ADC and FPGA interface, clock management, and high speed data access were designed based on hardware modules. The digital storage oscilloscope module was successfully applied to the practical test system, whose performance was good, stable, and achieved the desired design goals.
The process and design scheme of IETM system based on GJB6600 standard was introduced in this paper, and automatic control equipment maintenance was studied with IETM data description and storage technology,the data description scheme, data storage and query framework were established, realized the conversion from XML data to relational database, and the small IETM browsing prototype was developed. This project had important significance to shorten the maintenance time and improve the efficiency of equipment protection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
