【摘要】 电子工业的发展对自动测试效率的要求越来越高,而微波被测信号的功率动态范围却越来越宽。为提高测试效率,需要开发微波功率调理模块,灵活方便地将微波被测信号的功率调整到合适的范围,以便后续仪器测试。本文介绍了一种基于S3C2410嵌入式系统芯片的微波功率调理模块设计方法。该模块以PC机作为上位机,可通过USB总线、LAN总线和RS232总线控制,具有很强的可靠性和灵活性。实际应用表明,该模块结构简单,应用灵活,易扩展,具有广阔的应用前景。更多还原

【Abstract】 The power dynamic range of microwave signal to be measured is becoming broader in today’s Automatic Test System (ATS) , to meet the increasing requirements of ATS. To improve testing efficiency, the microwave power adjustment module is needed to adjust the power of signal to be measured to the appropriate range to satisfy the need of the subsequent test. This paper discussed the design of the microwave power adjustment module based on S3C2410 ARM-kernel processor. The module uses computer as the host, it can be controlled reliably and flexibly through USB bus, LAN bus or RS232 bus. The application of this module demonstrated the advantages of the module: simple structure, flexible application, easy extension. These facts also prove that this method can greatly increase the automatic test efficiency and it can be applied in a very broad way.更多还原
