外部测试 meaning in English
external test
Examples
- Research of testability based on performance parameter detection and external test
基于性能参数检测与外部测试的测试性探讨 - With the sharp development of lsi and vlsi , the integration of chip gets denser and denser . but the extra ports for testing is limited and test is more difficult than before . we even must spend more time and money on chip testing rather than chip design
大规模集成和超大规模集成电路迅速发展，使芯片的集成度越来越高，而供外部测试的引脚却很少，测试问题日趋困难，甚至使芯片测试比芯片本身的设计和生产要付出更高的代价。 - The system includes three parts : ( 1 ) , exterior bus and high frequency signal data acquisition and signal processing ; ( 2 ) , pc - daq data acquisition . it solves some problems about continuing data acquisition , data stream storage and multi - tasks disposal ; ( 3 ) , real - time monitor work - state of twelve relays
该系统主要包括三个部分：第一部分是外部总线以及对高频信号的采集与处理，它主要解决了系统与外部测试仪器的通讯，借助示波器实现了高频信号的采集；第二部分是pc - daq数据采集设计，这部分完成对九路低频信号的采集。
