Abstract: The microwave measurement experiment is an integral part of microwave technology courses. A microwave measurement experiment based on the attenuation of the adjustable attenuator is designed. Students are guided to use spectrometer or power meter as a measurement tool, design the experimental procedures independently, and obtain the attenuation characteristics by hardware measurement and data fitting according to the usage requirements of the adjustable attenuator. The obtained results are used in subsequent experiments. It has been found that the experiment allows students to master the attenuation calibration method by applying typical microwave measurement instrument, deepen their understanding of the attenuation concept through straight-forward phenomenon, actively explore and design the experimental procedures according to usage requirements, thereby honing their abilities to design microwave engineering, analyze and solve problems.
