余度数据总线电气隔离度的测试与分析

"余度数据总线电气隔离度测试"是检验在数据总线和余度电缆之间存在电气耦合度的大小.通过对数据总线屏蔽层在接地与不接地状态下的电气隔离度测试,分析了"有传输活动"电缆对"无传输活动"电缆干扰的特征,阐述了电缆屏蔽层的良好接地是确保余度数据总线电气隔离度满足要求的关键.

The Test and Analysis of Electric Shielded Isolation Limit about Redundant Data Bus

The test of the electric shielded isolation limit about redundant data bus is checkout electric coupling extent between data bus and redundant data bus.The article analyses a characteristic of the interference on transfers action line to nought transfers action line,and expatiates a good grounding of the shield-sheath to be the key that to insure the electric shielded isolation limit about redundant data bus satisfy request of GJB289A-97 by the electric shielded isolation limit tested under the state of gro...
