差动测量探测器具有用于将差动探测尖端的外部屏蔽导体电连接在一起的接地夹系统。

A differential measurement probe has a ground clip system for electrically coupling outer shielding conductors of differential probing tips together.

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。

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.

由于闭合、中空导体中的电场为零，所以，使用法拉第杯就把放在其内部的物体屏蔽起来，不受大气的或任何寄生的电场的影响。

The electric field within a closed, empty conductor is zero, so the cup shields the object placed inside it from any atmospheric or stray electric fields.
