怎么都是广告呀!
是不是电磁干扰的影响,我这里有一段话可以参考一下,我也一直没弄明白具体意思。
if the event of difference in potential between machine ground and ground of electronic circuit,
appropriate measures must be taken to prevent equalizing currents from flowing via the cable
shield(eg by providing for large-section equipotential bonding conductors or by using cables with
separate double shielding where the shields are connected only at one end ), 这段话语地线有关,但对技术不是很了解,所以直接搞不懂说的是什么, 另外注意信号线一定要远离动力线。
