It's really hard to tell whether RFI you see with a probe like that is 
going to be an issue. They're most useful when you DO have an issue, and 
you're trying to track down the source.

FWIW, I have a 1500 VA Cyberpower UPS in the station, and I've never 
detected any RFI from it. However, my noise level is fairly high, so 
there might be some detectable in a quiet QTH.
