随着电子技术的发展,各种带有 GP-IB 接口的测量仪器越来越多。因此使用通用的微型计算机,配以相应的 GP-IB 适配器,与带有 GP-IB 接口的测量仪器一起可以组成各种自动测量系统。我们在利用IBM-PC/XT286计算机与音频分析仪构成音频自动测量系统时,碰到了一些问题,也积累了一些经验。现在把这些经验介绍给大家,或许能起到抛砖引玉的作用。(1)当你把适配器插入计算机扩充槽内,与仪器用电缆连接好后,再执行一段专门为其编制的程序时,仪器无任何反映,而计算机屏幕则显示出返回码“TIMEOUT”。对于这种情况你往往会怀疑适配器好否、所编程序正确与否。但当你的适配器是新买的,而
With the development of electronic technology, a variety of measuring instruments with GP-IB interface are more and more. Therefore, the use of general-purpose microcomputer, with the corresponding GP-IB adapter, with GP-IB interface with the measuring instruments can be composed of a variety of automatic measurement system. When we used the IBM-PC / XT286 computer and audio analyzer to form an automatic audio measurement system, we encountered some problems and accumulated some experience. Now introduce these experiences to everyone, may play a valuable role. (1) When you insert the adapter into the computer expansion slot and connect the instrument to the cable, execute a program specially programmed for it without any reaction from the instrument, while the computer screen displays the return code “TIMEOUT”. For this situation you often wonder if the adapter is correct or not. But when your adapter is newly bought, instead
