Re: Good USB Cables #usb
This is a tough one because the makers claim of being "screened" or shielded may or may not mean anything as far as being a quality cable and help tame RFI issues.
In my prior tempest life
before specifying a certain cable assembly we would of course
run tests in the lab. It was convenient working for a large
defense firm as we had access to SEM and x-ray facilities just
a few hall ways away. You would be shocked how many commercial
cables we x-ray'ed showed that while they did provide some
form of shield (usually a thin cheap aluminum foil) where the
ends were 100% totally unterminated. Only a few we found
actually terminated the shield to the case which is a must if
the shielding is to do any good. Just wrapping a cable in foil
buys you ziltch.
