Radio Frequency Interference from USB 3.0

In 2012 Intel documented the Radio Frequency Interference that can be produced by USB 3.0

It notes: USB 3.0 or Superspeed USB has a 5Gbit/s signalling rate. The USB 3.0 specification requires USB 3.0 data to be scrambled and it requires spread spectrum to be applied to the clock.

The data spectrum is very broadband ranging from DC to 5 GHz.
