1、当然,冇应用的个人电脑的所右者可能想比仅通过GPIB与各种设备的奇数,提供更高的性能。这种系统通常称为基于PC的工作站。在基于PC的工作站,仪器模块匹配性能和兼容性都聚集圉绕PC电脑。基于PC的丄作站允许來自多台仪器的数据迅速聚集,存储,作图,分析,并纳入一台PC机上的报告形式。这种类型的系统一般都放在一个制适商合作,以提髙性能和涉及的仪器模块之间的合作。Thereare,ofcourse,applicationsforwhichtheownerofaPCmaywanthigherperformancethanthatofferedbytheGPIBalone,withitsoddassor
