The EM Test CCI Capacitive Coupling Clamp is ideal for fulfilling EN 61000-4-18, EN 61000-4-4, IEC 61000-4-18 and IEC 61000-4-4 standards. EM Test CCI Capacitive Coupling Clamps are used to couple EFT/burst pulses to I/O lines as required in different European and international standards for immunity testing. The coupling of the Electrical Fast Transients EFT/burst to signal lines can usually not be achieved by discrete capacitive coupling without interfering with the signal flow, thus the EM Test CCI's functionality. It is often impossible to contact the required circuit (direct), e.g. coaxial or shielded cables. In this case the coupling is realized by the capacitive coupling clamp. The interference simulator can be connected on both sides of the coupling clamp.The IEC 61000-4-4 Ed 3.0 published 2012 recommends the calibration of the capacitive coupling clamp into a 50ohm coaxial load with the normative calibration kit CCI PVKIT 1.
