1. Summary
EM5070A coupling/decoupling network CDN-M2/M3 is the product used for EMI test, it can provide stable impedance between the device under test and the reference ground in RF range and insulate the test circuit from the useless signal from the electric network, coupling the interference signal of the device under test to the input port of the test receiver.
Designed according to national standard GB/T17626.6-2008/IEC61000-4-6：2006 and requirement for CDN- M2/M3 coupling/decoupling network (CDN-M2 double line, CDN-M3 triple line,) EM5070A combine both CDN-M2 and CDN-M3 test methods. Users can proceed measurement to M2 and M3 with only one EM5070A.
Coupling/decoupling network (CDN) can be used for can be used for the 150kHz~300MHz radio interference testing of the electric lighting device according to national standard GB17743-2007 /CISPR15：2005/EN55015. The detailed testing method can refer to the standards above.
EM5070A can be well used for single phase device conduct test. According to the design theory, there could be relatively large leakage current, good grounding is necessary during operation. Isolation transformer will be needed to cooperate in necessary cases, and our EM5060 (900VA) can satisfy most testing requirement.
