Introduction:
CDN S4 4XBNC is a 4 BNC connectors coaxial shielded cable coupling decoupling network equipment from Schwarzbeck, Germany, can be used for impedance of 50 Ω coaxial shielded cable for conducted immunity testing, the product authorized by the Shenzhen EUTTEST agent sales and quotation service. The device meets the requirements of IEC 61000-4-6, Figure D.1, and can be used for conducted sensitivity testing of coaxial cables with 50 Ω impedance, supporting a maximum DUT input of 100 V AC or 150 V DC, and with a rated current of 0.25 A. The bottom of the device is equipped with a notch for connecting to a reference ground plane.
We also offer another CDN S1 BNC 75 can be used for conducted immunity testing of coaxial cables with 75Ω impedance.The
