Vic I believe that the diagram is for indicative purposes and attempts to show all test configurations. Thus when I perform this testing I use one continuous earth plane to which the EUT is earthed mounted on 10cm supports (if the EUT is not floor standing). Have a look at figure 9. Thanks Ian Gordon

Two reference planes are shown. One along the bottom edge of the figure which I believe implies a plane beneath ALL equipment shown - e.g. the floor of a screened room - and a second plane specifically beneath the capacitive clamp. If testing is performed in a screened room, is the second reference ground plane required? If it is required should it be bonded to the overall reference plane ( it is insulated from the overall reference plane by floor tiles)? If not required should the clamp be bonded to the overall reference plane? Your views and comments would be most appreciated.
