EMC中传导骚扰检测一定要在屏蔽室内进行吗？作者: kamleung 时间: 2010-12-10 17:39
In most of EMC standards, the interference voltage test (Line Conduct Test) is not particularly required to have the test in a shielded room. However, to eliminate the affects coming from the background noises, almost all laboratories would prefer getting this test in the shielded room.作者: mypcb 时间: 2010-12-20 11:36
因骚扰电压是属于线上干扰,而非空间干扰,标准中未规定骚扰电压一定要在屏蔽室内进行0 S5 \! A& e. l V- W4 F7 F
