Atec Teseq-Schaffner-CDN500 - 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 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 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.
