人工电源网络的主要校准参数是电压分压系数、阻抗、相位等 人工电源网络（AMN） artificial mains network(AMN) 在射频范围内向受试设备端子之间提供一规定阻抗，并能将试验电路与供电电源上的无用射频信号 隔离开来，进而将骚扰电压耦合到测量接收机上。人工电源网络有两种基本类型：分别用于耦合非对称 电压的V型和用于耦合对称电压和不对称电压的Δ型。线路阻抗稳定网络（LISN）和V型人工电源网络可 替换使用。 人工电源网络阻抗 人工电源网络的阻抗规范包括当骚扰输出端端接50Ω负载阻抗时在受试设备端测得的相对于参 考地的阻抗的模和相角两个部分。 人工电源网络EUT 端的阻抗定义为对受试设备呈现的终端阻抗。因此，当骚扰输出端没有与测量 接收机相连时，该输出端应端接50Ω阻抗。为保证接收机端口具有准确的50Ω终端阻抗，可在网络的 内部或者外部使用10dB 的衰减器，衰减器的驻波比（从任何一端看进去的）应小于或等于1.2。该衰 减应包括在电压分压系数的测量中。 不对称人工网络(AAN) asymmetric artificial network(AAN) 用于测量非屏蔽对称信号（例如电信）线上的共模电压（或将共模电压注入到非屏蔽信号线上）同时具有抑制差模信号功能的网络。
The main calibration parameters of an artificial mains network (AMN) are voltage division coefficient, impedance, phase, and so on. Artificial Mains Network (AMN): It provides a specified impedance between the terminals of the Equipment Under Test (EUT) within the radio frequency (RF) range, isolates the test circuit from unwanted RF signals on the power supply, and couples the disturbance voltage to the measurement receiver. There are two basic types of AMN: the V-type for coupling asymmetric voltage, and the Δ-type for coupling both symmetric and asymmetric voltages. The Line Impedance Stabilization Network (LISN) is interchangeable with the V-type AMN. AMN Impedance: The impedance specification of AMN includes two parts: the magnitude and phase angle of the impedance measured at the EUT terminal relative to the reference ground when the disturbance output terminal is terminated with a 50Ω load impedance. The impedance at the EUT terminal of AMN is defined as the terminal impedance presented to the Equipment Under Test (EUT). Therefore, when the disturbance output terminal is not connected to the measurement receiver, this output terminal shall be terminated with a 50Ω impedance. To ensure that the receiver port has an accurate 50Ω terminal impedance, a 10dB attenuator can be used either inside or outside the network. The standing wave ratio (SWR) of the attenuator (as seen from either end) shall be less than or equal to 1.2. This attenuation shall be included in the measurement of the voltage division coefficient. Asymmetric Artificial Network (AAN): A network used to measure the common-mode voltage on unshielded symmetric signal lines (e.g., telecommunications lines) or inject common-mode voltage into unshielded signal lines, while having the function of suppressing differential-mode signals.
