The term "Lo-fi" or "Low Fidelity" means a non-working model while a "High Fidelity" model is a working model.
术语“低保真”的意思是一个非工作模型，而“高保真”模型是可工作模型。
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。
With the correct connection scheme shown in Figure 3-13a, the low or chassis side of the voltage source is connected to input LO of the measuring instrument.
在图3-13a所示的正确的连接方式之下，电压源的低端或者机箱端连到测量仪器的输入低端。
