EM Test Type HFK Capacitive Coupling Clamp

The EM Test Type HFK Capacitive Coupling Clamp is used to couple EFT/burst pulses to I/O lines as required in different European and international standards for immunity testing such as burst testing per IEC 61000-4-4, Basic Standard.

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. 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.
