【摘要】 介绍了一种低热电势程控多路开关的工作原理和使用方法。该多路开关配以双地址只听ＩＥＥＥ－４８８接口，可用微机控制，也便于手动操作。本多路开关可为１６通道（每通道４个接点），也可为３２通道（每通道两个接点）。更多还原

【Abstract】 The principle and operational procedure of a low thermal EMP multiplexer areintroduced. This device with a double-address listen-ohly IEEE-488 interface can be operating eitherin programmable or in manual condition. It can be used as 16 channels with 4 contracts or as 32channels with 2 contracts.更多还原
