  2. 電磁干擾（EMI） 輻射 (Radiation)：經由空氣或其它介質發射 　　　　　　　　出去的高頻電磁波 傳導 (Conduction)：經由導線所傳播出去的 　　　　　　　　低頻電磁波

  3. EMC 乃電磁相容(Electromagnetic Compatility) • 含蓋電磁干擾EMI (Electromagnetic Interference) 和 • 電磁耐受性EMS (Electromagnetic Susceptibility) ; • EMI 為電磁場伴隨著電壓﹑電流的作用而產生, • EMS 為產品在使用過程中不受周遭電磁環境影響的能力。 • 造成EMC 的三要素 • 干擾源(Source of EMI) : 自然的﹑人為的 • 干擾路徑(Propagation Mode) : 傳導﹑輻射受害者(Receivers) : 電視機﹑收音機﹑無線電話﹑飛機﹑醫療設備……等 • EMC 問題的現象分類: • (1) 低頻傳導現象(2) 低頻輻射現象(3) 高頻傳導現象(4) 高頻輻射現象(5) 靜電放電現象(6) 高空核爆效應

  4. EMI Couple Path 1. Direct radiation from source to receptor 2. Direct RF energy radiated from the AC mains or signal/control cables of the receptor 3. RF energy radiated by AC mains, signal, or control cables from source to receptor 4. RF energy conducted by common power supply lines or signal/control cables

  5. EMI 相關組織 CISPR (Comite International Special des Perturbations Radioelectriques）：國際無線電波干擾委員會 FCC (Federal Communications Commission)：美國聯邦通訊委員會 CE：歐盟 VCCI (Voluntary Control Council for Interference)：日本 C-Tick：澳洲 NCC/BSMI：台灣標準檢驗局

  6. 相關法規介紹 • FCC相關測試規範 • PART 15B/CISPR 22：資訊類產品 • PART 15Ｃ：無線通訊產品 • PART 18：醫學，科學類產品 • PART 68：連接公眾網路類產品，如電話 • 歐盟相關測試規範 • EN55022：資訊類產品 • EN301489： 802.11無線產品，EMC相關 • EN300328：802.11無線產品，RF相關 • EN/IEC61000-*：EMS測試 http://wireless.fcc.gov/rules.html

  7. EMC測試簡介 • Emission： • EN55022/FCC Part 15B：電磁干擾 (EMI) • EN61000-3-2：Harmonic • EN61000-3-3：Flicker • Immunity： • IEC61000-4-2：靜電 (ESD) • IEC61000-4-3：輻射耐受度 (RS) • IEC61000-4-4：EFT • IEC61000-4-5：雷擊 (Surge) • IEC61000-4-6：傳導耐受度 (CS) • IEC61000-4-11：電壓瞬降 (Dip)

  8. Radiation Emission Test • ．量測待測物在一開放空間中運作時所發射出來的 • EMI雜訊 • ．量測場地分Chamber (Pre-test)與Opensite (Final test) • 兩種 • ．資訊類產品的量測範圍分為以下兩種 • 150KHz~30MHz：Power line conducted emission test • 30MHz~1000GHz：Radiated emission test

  9. Test Environment-OATS OPEN-AREA TEST SITES(OATS)

  10. Radiation Test Setup

  11. Test Environment-Chamber Ferrite tile chamber
