Here's the correct way of measuring a Power Plant

Regarding the PowerPlant’s ability to attenuate AC line noise, particularly higher frequency spectra, please read my posts in this thread, “Power Plant and Noise”, starting from this post:

Power Plant and Noise

AC regenerators (essentially power amplifiers) do many wonderful things, exactly as claimed, in the area of delivering clean and pure low-impedance, high power AC - up to a certain point, constrained by its rated output. Not to nit-pick, but I’d like to better understand its less-well-understood shortcomings. As I had suspected, while reduction of both common-mode and differential-mode noise is “spectacular” up to the AC regenerator’s upper bandwidth, above this, which is to say, unfortunately…
