Well, darn. Unfortunately, I am not right now in a position where I can procure or look at standards. However... I am disappointed that the writers took the route they did. I thought we were moving away from running cables across the ground plane where we could avoid it, and here they require we do so. I am not really surprised, but while putting a clamp on the floor is the simplest way to add the controlled impedance and attenuation required, it is only _one_ way to provide it. Putting clamps under the floor might actually permit more repeatable measurements and could be just what was needed for "harmony." I suppose someone will have to perform a series of measurement to SHOW the Commission that clamps do not give manufacturers an edge in passing radiated emissions testing. Of course, if it turns out that clamps DO help pass, we're back to two different tests.
