摘要

MIL-STD-462 CS02导敏试验装置包括一个音频变压器，二次变压器用作电感器，以及一个大电容。这两个元件加在一起，形成一个l型低通滤波器，最大限度地减少注入测试信号输入电源。一些飞行硬件电源输入配置与此设置不兼容，上电时进入振荡。这反过来又会损坏飞行硬件。在美国戈达德航天飞行中心(GSFC)的大型电磁兼容性(EMC)测试设备中，由于振动导致了一个项目的灾难性失效。

Potential damage to flight hardware from MIL-STD-462 CS02 setup

The MIL-STD-462 CS02 conducted susceptibility test setup includes an audio transformer, with the secondary used as an inductor, and a large capacitor. Together, these two components from an L-type low-pass filter to minimize the injected test signal input into the power source. Some flight hardware power input configurations are not compatible with this setup and break into oscillation when powered up. This, in turn, can damage flight hardware. Such as oscillation resulted in the catastrophic failure of an item tested in the Goddard Space Flight Center (GSFC) large electromagnetic compatibility (EMC) test facility.
