CDN 500
Capacitive coupling clamp
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 charac-
teristic 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 re-
sistor. 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 diam-
eter. The effective coupling capacitance depends on
the cross section and the material of the cable used;
a typical value being around 100pF.
