一、前言 日本TEAC公司生产的实时数字相关机C-120和频谱仪F-120,虽然测量点数较少,但它的分析频段可达1M,这是其它设备难以达到的。由于原配终端为小型机,价格昂贵,很多单位没有买,致使测量结果不能输出,失去其实时优越性,且无法再处理。我们用廉价的Apple-Ⅱ加上6820并行接口适配器,和C-120及F-120相接,不仅实现了测量结果的准确快速输出,而且能把结果储存、再加工以及图形考贝。在时延估计、系统时变分析等领域获得了广泛的应用。本文介绍两个系统对接技术及有关问题。
I. Preface The real-time digital correlation machine C-120 and F-120 made by Japan TEAC Company can measure up to 1M, even though it has fewer measurement points, which is hard to achieve by other equipment. Since the original terminal for the minicomputer, expensive, many units did not buy, resulting in measurement results can not be output, lose their real-time superiority, and can no longer be processed. Using the cheap Apple-II plus the 6820 parallel interface adapter, the C-120 and F-120 interface not only enables accurate and rapid output of the measurement results, but also saves, reworks, and graphically tests the results. It has been widely used in the field of time-delay estimation and system time-varying analysis. This article describes two system docking technology and related issues.
