3.1 asymmetric voltage unsymmetricvoltage the vector magnitude of the RF disturbance voltage that appears between a single power terminal and ground.

3.2 Test end impedance EUTportimpedance Refers to the line terminal and reference of the device under test when the disturbance output of the artificial power network is terminated with a 50ohm load impedance.

High frequency impedance (modulus and phase angle) between the test sites.

3.3 partial pressure coefficient voltagedivisionfactor Refers to the high frequency signal fed from the device under test, transmitted to the disturbance output via the internal power supply network (built-in attenuation) the magnitude of the amplitude experienced by the device within the calculation range.

4 Overview

The artificial power network is an instrument used in electromagnetic compatibility radio disturbance measurement tests to measure power lines and parameters.

The disturbance voltage radiated externally between the test sites is usually an asymmetric voltage. Artificial power network in the harassment test the role of the quantity is.

1) providing a specified impedance to the terminals of the device under test in the RF frequency range;

2) coupling the disturbance voltage emitted by the device under test to the disturbance measuring device;
