本論文旨在研製一套可應用於量測印刷電路板上之電磁干擾雜訊的系統，此系統主要包含兩個部分 : 掃描量測系統和自動量測系統。在掃描量測系統中，掃描器作為印刷電路板的量測平台，設計T型微帶天線作為陣列探棒，按2 x 12之陣列排放，各探棒分佈在15 mm x 15 mm的矩形柵格內，當作量測訊號之元件，並連接寬頻帶放大器將所接受到之訊號傳至頻譜分析儀。自動量測系統實現掃瞄器內探棒開關自動切換、移動，以及控制頻譜分析儀進行濾波與掃頻，以及接收由頻譜分析儀傳來之資料，做電腦監控和資料收錄，最後呈現印刷電路板上電磁場之空間分布圖像，經由實驗結果證實可達到定位量測及其目的。

　　This thesis presents the system of measuring electromagnetic interference on the printed circuit board, which is mainly composed of the scanning sub-system and the automated test equipment(ATE) sub-system. In scanning sub-system, the scanner is as measuring platform of the PCB. In addition the array probes are made up of the T type microstrip antenna as component for signals measuring, according to the array of 2 x 12 placed, each probe distributes in the square area of 15 mm x 15 mm; the array probes connect to spectrum analyzer by the broadband amplifier. The automated test equipment sub-system, fulfills the probes automatic switching and moving, controls filtering and scanning frequency of spectrum, and receives data from spectrum. Finally, it displays chart of space distributing on the electromagnetic interference of the printed circuit board. The experimental results verify the purpose of position measuring is achieved.
