【摘要】 介绍了测试系统中的各类干扰源。对来自系统外部的自然干扰、放电干扰、工频干扰、射频干扰、静电干扰及来自系统内部的电源干扰、地线干扰、信号通道的耦合干扰等的产生原因作了较详细的分析更多还原

【Abstract】 Various interference sources in test system are introduced. External interference, e. g., nature interference, electricity discharging interference, main frequency interference, radio frequency interference and static electric interference; and internal interference, e. g., power interference, grounding interference, coupling channel interference between signal channels; as well as their forming causes are analyzed in detail.更多还原
