本文以pxi總線虛擬測試系統為核心，輔以程式控制電壓源、高壓衰減探頭、高壓繼電器、高壓放電負載及氣動裝置，分別設計組裝了主機櫃與測試櫃，完成整個自動測試進程。Secondly, methods of improving on probe are investigated in detail : using the electromagnetic shielding effect to decay the direct - coupled magnetic field and using the dual probe to control the energy flow, so as to make the probe to be shorter ; designing 3 - d pick - up coil array to increase detection sensitivity. at last, experiment system is set up to verify the simulation result and the comparing result shows simulation result agrees with experiment result
其次，對改進傳感器性能的幾種方法進行了詳細研究:利用電磁屏蔽效應以衰減在直接路徑上的磁場傳播、採用復式探頭激勵方式以實現能流控制，從而減小傳感器體積，模擬證實這兩種改進方案有效;設計三維周向檢測線圈陣列以提高缺陷檢測靈敏度，模擬結果證實三維探頭的周向靈敏性。This paper has analyzed the characteristics of near - field electromagnetic fields and the measurement principle of magnetic - field sensor, and designed probe, amplifier unit and compensator according to measurement needs. finally, based on the electromagnetic pulse simulator in the lab, a set of experiments have been done on the designed magnetic fields measurement system and analyzed the error of the measurement system
文中分析了近場電磁場分佈的特點；研究了磁場探頭的測量原理；根據實際測量需要製作了磁場探頭、設計了信號放大單元和用於補償電纜信號衰減的補償器；最後利用實驗室的電磁脈沖模擬器對所設計的磁場測量系統進行了一系列實驗，分析了系統的測量誤差。
