Interesting, thank you for doing the video. I guess the adaptor can can be used with a spectrum analyser to find out the impact of equipment like UPS or VFD; 1. How 'dirty' is the incoming power supply 2. How much 'dirtier' the equipment makes it Any thoughts?
The device allows you to troubleshoot mains power line noise, either using a spectrum analyser or an oscilloscope. With conducted emissions, I would use a spectrum analyser, but with transient events, such as relay on off, I would definitely use an oscilloscope to capture the noise. In a typical industrial environment, what you find you get both types of noise, it is just the nature of the electronics. As per our friend's comments down below, it is interesting. Because how can we trust the results we measure? Most engineers have a bias, who believe the more expensive the measurement equipment is, the more they trust the results. I personally try to use quality products, and I have this "trust but verify approach".
I think it is more than a high-pass filter. I actually spoke with their engineers at one point, it is quite challenging to design this device because it is made for measuring mains voltage, so leakage current must be kept low.
I have some "dimmable" LEDs that sometimes when the dishwasher is running get really blinky. I'd love to see if that is between the dimmer and the bulbs or in the whole circuit. I'd love to have one of these for a week or two!

Maybe I am just dum but isnt that box just a hi-pass filter? Thanks for great videos! / Tomas

@@MachOneDesignEMC when looking fast on problems they very often seem simple. When looking in depth on problems it is almost always complicated 🤣
