Coupling / Decoupling Networks (CDN)耦合非耦合網路
依據 IEC61000-4-6 射頻傳導抗擾性之法規其要求之測試範圍為150KHz 至 80MHz
測試時需使用到CDN之目的提供一種間接信號能量耦合方式,目的是將射頻干擾能量能透過此種藕合方式將信號能量耦合至待測物 ( EUT ) 端而不至於將能量耦合至 ( AE ) 端干擾到非屬待測物端影響到測試之主要目的-針對不同待測物有不同測試用CDNs 每一個CDN皆包含具容性耦合與針對感抗耦合之高阻抗線圈
此干擾信號透過CDN被耦合注入至待測物之 電源線 或是 信號線 - 執行待測物測試之前需針對所使用之CDN不同執行不同之CDN之校正
校正配件:
2 units of the 150 Ohm to 50 Ohm adapter
1 unit of the 50 Ohm Terminator ( 50ohm 終端器 )
Optional Ground plane
