Why do we need quasi peak detectors for EMC tests? 

Thank you for your great Video and for the time you take to share you knowledge.

Thank you for the great demo. I am also interested in your spark generator. Is it with a lighter from Doug Smith's article?

Excellent video as usual. Any comments on how to implement a QPD in the time domain? I notice you have done some recent videos where you do the conducted emissions testing in the time domain and then do some FFTs. Presumably doing the QPD this way is also feasible?

Thanks a lot.

What is the book, Min? Title/Author? ... Edit: Found it! ... "Electromagnetic Compatibility Engineering" by Henry W. Ott.
