FH465型是FH451型1024道分析器的更新改进产品,除具有原仪器操作简便、显示精细等特点外,以半导体存储器取代了磁芯存储器,并提高了集成度,采用国际上通用的74LS低功耗器件,使成本大幅度降低,又可方便地与APPLE-Ⅱ,长城-0520-CH及IBM-PC/XT等微机联机。 本文介绍FH465型1024道幅度分析器的工作原理及主要技术性能。
The FH465 is an updated and improved product of the FH451 1024-channel analyzer. In addition to the simple and easy operation of the original instrument and the fine display, the FH465 replaces the magnetic core memory with semiconductor memory and improves the integration. The FH465 adopts internationally accepted 74LS low power Consumption of components, so that significantly reduce costs, but also easy and APPLE-Ⅱ, Great Wall -0520-CH and IBM-PC / XT and other micro-computer online. This article describes the working principle and main technical performance of FH465 1024-channel amplitude analyzer.
