一种微波功率计自动校准系统设计与实现

摘要

The limitations of present calibration procedure for microwave power meter(MPM) is described. An automatic calibration system for MPM was designed on the basis of Visual Basic software platform. The system hardware composition, working principle, application program design and uncertainty assessment are elaborated. The actual application shows that this system has the features of easy operation, high efficiency and high measuring accuracy.%针对传统的手工校准微波功率计的局限性,设计并实现了一种基于Visual Basic软件平台组建的微波功率计自动校准系统.详细阐述了系统的硬件构成、工作原理、应用程序的设计以及不确定度的分析和评定.实际应用表明,该系统具有操作使用方便、测量精度高等优点.
