摘要
某飞机重力仪的辐射发射超标,通过分析其UPS、电源模块、显示器数据线等对整个系统电磁骚扰的贡献量,分别采取了安装滤波器、加装屏蔽盒、改善接地等整改措施。整改后,重力仪的辐射发射测试结果合格。
The radiate emission test result of an aircraft gravimeter does not meet the limit line. By analyzing the contribution of the UPS, power supply module and monitor data line to the electromagnetic disturbance of the whole system, the corrective measures such ＆s installing the filter, installing the shielding box and improving the grounding are taken respectively. After the ~ctification, the radiate emission test of the gravimeter results qualified.
