this signal is most likely to be produce from the computer itself i.e. 480mb/s tune clock of isb 2.0 but can't get so assuring.

Yes, this is USBUpper Side Band Modulation (Radio, referring to reception and modulation mode)Universal Serial Bus (Computer, referring to USB Ports and cables) 2.0 noise. https://www.sigidwiki.com/wiki/High_Speed_USB_Noise --Cartoonman (talk) 16:35, 16 March 2018 (NZDT)
