摘　　要：随着物联网技术和智能仪表的飞速发展,RS-485在新的领域内得到了更广泛的应用,随之而来的,也对RS-485收发器的可靠性与误码率提出了更严苛的要求。针对RS-485收发器快速瞬变脉冲群的测试,通常是基于系统,例如在低速的智能电表中完成的。本文介绍了一种高速RS-485收发器快速瞬变脉冲群测试系统的设计,可以作为一个通用平台完成对RS-485收发器的对比测试,同时兼顾高速和低速系统,完成通讯误码率的统计分析。With the rapid development of IoT and smart meters,RS-485 has been widely used in new fields.Mean-while,more stringent requirements have been put forward on the reliability and communication error ratio of RS-485 transceivers.Usually EFT/B test for RS-485 is based on system,for example,low-speed smart meter.This article introduces the High-speed Electrical Fast Transient Burst Immunity Test System,which can be used as a general platform to complete the comparative test of RS-485 transceivers,taking into account both high-speed and low-speed systems,and complete the communication error rate Statistical Analysis.
