According to the latest changes in the IEC/EN 61000-4-4 edition 2 standard, which is mandatory since October 2007, verification of the burst waveform is required through a 50 and 1000 ohm load. The Haefely EMC EFT Verification set includes all neccessary attenuators and additional cabling and documentation, that allow users to connect to comercial oscilloscopes and verify the waveshape as required by the latest standard. To verify impulses at the CDN output, special adapters can be used together with the attenuators.
