[SCCC] OT: low RFI USB-C power supply?

[Drew Arnett]

I've started chasing down a new noise source at home.  (Early
assessment shows it's getting on the AC wiring and conducting all over
the house.)  Probing around, looks like a new piece of gear that is
powered by USB-C and has a USB-C wall wart that was included is quite
RFI hot.  I'm hoping it's the supply and not the load, so swapping
supply might cure it.

USB-C power supplies are somewhat new.  None are going to be specified
for conducted or radiated RFI.  Has anyone done any evaluations, so I
can simply purchase once?  Or do I have to do the equipment
evaluations?

Thanks and best regards,

Drew
