本文报道我们研制的一种自动测量线系统。该系统由测量线、步进电机、APPLEⅡ微型机和有关硬件组成,并在软件编程技术的支持下工作,它不仅能像传统的测量线一样用于微波测量系统中,而且能自动采集数据、快速处理数据、给出最终结果。此外,无需添加任何设备就能测量大至短路的各种驻波比,从而为自动测量低耗介质的复介电常数提供一种简便、快捷的测量装置。
This article reports an automatic measurement line system that we developed. The system is composed of measuring line, stepping motor, APPLEⅡcomputer and related hardware, and is supported by software programming technology. It can not only be used in microwave measurement system like the traditional measuring line, but also can automatically collect data, Quickly process the data to give the final result. In addition, it is possible to measure a wide range of VSWRs from short to long without adding any equipment, providing a simple and quick measurement device for automatically measuring the complex permittivity of low-loss media.
