How can I measure the output waveform form the CDN output of my FNS series EFT/B simulator, which I recently knew is a requirement newly added in the IEC 61000-4-4 edition 2.0 amendment 1. (amendment 1 to the second edition)?NoiseKen
According to the standard, the waveform shall be individually verified for each coupling line at each output terminal (L1,L2, L3, N and PE) of the coupling/decoupling network with a single 50 Ω termination to reference ground.
The verification is performed with the generator output at a set voltage of 4 kV. The individual outputs of the CDN (normally connected to the EUT) are terminated with a 50 Ω load while the other outputs are open.
For this purpose, AT-810 50 ohm attenuator and 02-00131A conversion adapter (screw terminal to coaxial) is available. The Noiseken FNS simulator and its options use the manufacturer-designed HV coaxial connectors. No connectivity with any commercially available coaxial connecters is provided.
