Teseq CDN 500

The coupling clamp CDN 500 is manufactured exactly in accordance with the drawings and specifications of ISO 7637-3 for capacitively coupling the transients onto cables and wiring harnesses. With its characteristic impedance of 50 Ω, the CDN 500 coupling clamp is connected to the generator via a coaxial cable and terminated on the far side with a 50 Ω load resistor. A suitable terminating load is available as an accessory under the type number INA 5030, which also provides a measurement output via a 40 dB attenuator. The coupling clamp will accept ribbon cables as well as round cables of up to 40 mm diameter. The effective coupling capacitance depends on the cross section and the material of the cable used; a typical value being around 100 pF.
