Abstract

The invention discloses an LXI-based parallel multi-channel reconfigurable instrument, comprising a substrate, an instrument function board, a field programmable gate array (FPGA) logical circuit, a test program set and a Web server, wherein the substrate and the instrument function board are the main components of the reconfigurable instrument and arranged in an instrument case together; the substrate is mainly used for realizing a software function and a hardware logical circuit of the system; and the instrument function board is mainly used for realizing the conversion between analog signals and digital signals. Based on the LXI standard design, the instrument is convenient for secondary development; the instrument has a multi-channel parallel test capacity, and each channel can flexibly change the function of the instrument; and the instrument can be used without installing software and can be operated and configured on line only by a browser.

Description

technical field [0001] The invention relates to a parallel multi-channel reconfigurable instrument based on LXI, which belongs to the field of automatic testing, in particular to the field of general testing based on LXI bus. Background technique [0002] The development means of the electronic system can be divided into two kinds of methods: hardware method and software method. On the one hand, the development of hardware systems can be customized for specific target tasks, and the operating efficiency is high, but the obvious disadvantages such as long development cycle, large development cost and low flexibility (reusability) limit its development. . The software system can well solve the shortage of the hardware system, but in the high-speed system with large data throughput, the data transmission rate and calculation rate often become the bottleneck of the software system. On the other hand, the development of a software system is inseparable from the hardware system ...
