EMF 390 shows 1800 V/m when connected to a laptop via USB, 3 V/m when disconnected.

Is there a cable that can remove the noise?

Some computers contain high EF when not properly grounded and affects the EMF meter when it's connected through USB. I don't think there's a USB cable that can remove the noise.
