Dear EMC-PSTC Group, In the new CISPR 22:1997 there are specified measurement of conducted disturbances at telecommunication ports, 5.2 table 3 and 4. The measurement procedure is described in 9.5, Measurement of disturbance at telecommunication ports. The suitable ISN's are described in Annex D, Schematic diagrams of impedance stabilisation networks. A. Does anyone have experience with building such ISN's - And using them? B. Does anyone have knowledge of whether such ISN's are commercial available, and if yes, where to buy them? Any comment to the issue will be appreciated. Best regards Helge Knudsen EMC Engineer Jyske EMC, Denmark [email protected]
