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

Cquk 1 month 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?

If you can manage a spectrum analyzer, you can use it to identify the frequencies of the noise produced by different devices and power supplies.

Of course. This was more an open ended question to see if others had noticed this and how they were approching it.
