Dare I mentionTEMPEST?
There are some buyers, the medical profession, the military, and commercial
aviation come to mind, who need emissions supressed if not for TEMPEST
reasons then because they must use digital equipment near communications
installations that are not only extremely sensitive, but that produce
substantial RF fields when transmitting.
Ham radio operators, too,
And as a rsult, EMC testers as well.
It is a real problem, not an imaginary one,and one that might well be looked
at by standards writers and legislators.
Can we afford DO-160 tested gear?

We tested a mouse when they first came out by tying the lease (cable) to a
stick braced between the legs of the table and dragging the little begger
around the outside of the turntable. The spectrum was spectacular! After
those first results, you'll notice the standards don't address any efforts for
causing the mouse or keyboard to be 'operated' during testing. Even today,
you'll find the mouse in the FCC under,
15.103 Exempted devices, along with others.
