The coupling clamp CDN 2012 conforms exactly to the requirements of ISO 7637-3 and other standards, guaranteeing that tests are carried out in strict compliance with the standard.
The CDN allows the fast nanosecond pulse bursts ( ISO 3a and 3b) to be injected in cable runs. Very high impedance signal lines are also to be found in vehicles on which the disruptive effects of ISO pulses 1 and 2 can also show up through capacitive coupling.
