Atec CDN500 User Manual

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 50Ω, the CDN 500 coupling clamp is

connected to the generator via a coaxial

cable and terminated on the far side with a

50Ω 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 40dB attenuator.

The coupling clamp will accept ribbon

cables as well as round cables of up to 40mm

diameter. The effective coupling capacitance

depends on the cross section and the ma-

terial of the cable used; a typical value being

around 100pF.
