| Abstract: | The parameters and waveform of the combination wave(surge) generator defined in GB/T 17626.5-2008/IEC61000-4-5:2005 are studied and analyzed.The calibration system for the ports of combination wave signal generator output and EUT the coupling/decoupling network(CDN) is set up.The test data generated from difference calibration test setup are compared.The factors that may influence the results are deeply researched.And solutions to improve the accuracy of calibration results are suggested such as isolated grounding and using U shape short circuit wire. |
