自动测试系统是各种自动测试仪器相互联接进行自动测量、分析和显示结果的总体。自动测试系统必须具备四个条件。1.可程控的仪器;2.控制器(计算机);3.接口(ATS的关键);4.测试软件。下面谈谈自动测试系统的由来及其前途。在自动测试系统中,接口总体称为接口系统,它包括母线和接口部分。母线为无源多芯电缆线,用于传送信息。接口由各种逻辑电路组成,对信息进行发送、接收、编码和译码。在60年代,自动测试系统获得广泛应用,并开始用计算机进行控制,它把不同功能的
Automatic test system is a variety of automatic test equipment connected to each other automatically measure, analyze and display the results of the overall. Automatic test system must have four conditions. 1. Programmable instrument; 2. Controller (computer); 3. Interface (ATS key); 4. Test software. Here to talk about the origin of automatic test system and its future. In the automatic test system, the interface is generally called the interface system, which includes the bus and interface section. Bus is a passive multi-core cable used to transmit information. The interface consists of a variety of logic circuits that send, receive, encode and decode information. In the 60’s, automatic test system was widely used, and began to use computer control, it put different functions
