RF Noise - Do you notice the RF noise floor has greatly increased with the influx of wall warts?

Cquk 10 months ago

I would be interested to see if any one else has noticed the issue. Maybe if you work on RF devices / have a spectrum analyiser etc.

Even some bench PSU's seem to produce more EMI than i would expect.

I am working on adding Ferrite's to all my cables but where does it stop?

They are built cheap, not as a quality power product.

100% the big problem is how do you identify a good quality vs bad quality at the time of purchase. It seems that compliance like CE is not being validated. Therefore you buy somthing and hope it works.

I have seen products like bench supplies also fail to be as clean as you would expect.

Yes, in the old days, you could buy quality power supplies that were very steady and produced very few artifacts.

Sadly those days are gone as we have mostly inexpensive devices that just barely suffice.
