In addition, there are instruments to prevent the leakage of good signal shielding.
此外，仪器还有防止信号泄漏的良好屏蔽。
It would also need good shielding and special electronics to filter the DSSS signal from the radio-noise created by the Earth, the sun and the rest of the galaxy.
同时还需要良好的外层保护和特殊电子器件，从地球、太阳及其太空中传来的无线电“杂音”中过滤出dsss信号。
Electrostatic shielding is provided by surrounding the signal path with a conductor connected to a low impedance point in the circuit, preferably the lo input terminal of the measuring device.
利用连接到电路中一个低阻点的导体，将信号通路包裹起来，即实现了静电屏蔽，该低阻点最好是测量设备的LO输入端子。
