: Re: Doubt with conducted emissions measurement Hi Brent, Specifically NOT meaning to argue, but only in pursuit of the TRUTH, isn't the 10 uF feedthrough cap a perfectly well-defined source impedance above, say 15/20 kHz, where the old MIL-STD-461A/B/C CE03 limit started? Which is not to say

Muriel, Coupling/Decoupling networks (of which LISN's are a subgroup) can affect DUT performance. I myself have not experienced this with a conducted emissions LISN, but I have experienced it with an EFT generator. We made a product that had an internal thermal printer. We EFT test in house.

Muriel, this is a very question, and I'll let better qualified people answer your specific concerns. Now, if I may add my 2 cents worth of experience in a 'similar' situation that involved conducted emission on SIGNAL leads: Under certain conditions, when the required CDN does interfere with

Muriel, 1) Your equipment must be designed to operate from the LISN. It must not resonate, generate extra ripple, etc. The concept is that EUT sees a low enough source impedance when connected to any real power distribution system that it operates in a STABLE mode. That means your input
