鑒於無線通訊產業的蓬勃發展,各家業者的競爭亦日趨劇烈,而產品的開發時間與測試系統往往是致勝的主要因素,在此前提下,整合之自動化測試平台開發就日驅重要。
但目前各測試平台多以測試IC裸板、天線、喇叭…等各相關零件為主,無法確實且有效的掌控成品品質,故開發針對成品全功能的整合自動化測試平台,是目前許多無線通訊業者所努力與追求的目標。而在開發全功能的自動化測試平台中,最重要亦是最複雜的關鍵即是整合後所產生之雜訊干擾問題。
此本論文即是針對目前通訊產業中主要測試項目- 射頻、音頻及耗電流…等以及自動化控制系統整合後,所衍生之雜訊干擾問題進行分析,並研究探討各項改善方案。
針對於射頻部份採用小型金屬電波隔離箱的設計,來隔離外部雜亂電波干擾與不明訊號,並結合傳輸線與天線等阻抗匹配設計以及內部電磁干擾防治對策,可大幅有效的排除射頻雜訊干擾、輻射性電磁干擾及傳導性電磁干擾,而得到與標準實驗室中之量測結果。同時為採用自動化控制與音頻量測,故亦對於各項控制機構、接觸性問題與收音問題,進行改善機構設計與吸音處理,以提高量測結果之準確性與重現性,此項結果將可廣泛的應用於各項無線通訊成品的測試平台開發。
The industry of wireless communication is booming and facing fierce competition. To shorten the product development schedule is important for survival. In general, the testing system is time consuming and inaccurate, because of independent testing modules.
Up to date, the testing modules are used for testing specific components such as IC bare boards, antennas, speakers, etc. However, the performance of the finished products cannot be measured precisely and effectively by the independent testing method, and easy happen erroneous judgments by human. An entire-function automatic testing system is required for the modern wireless communication industry.
In this thesis, we proposed an entire-function automatic testing system and investigated the noise disturbance during the testing in radio frequency, voice frequency, electric current loss, etc. A metallic chamber was optimized for the impendence matching to isolate the electromagnetic interference. The PC-based measurement system was developed for reducing the errors which were induced by human.
