The equipment under test was placed on a non-metallic table of height 0.8m.
At the side of the antenna input terminal of the equipment under test, a
non-metallic table of length 4m was placed at the same height to provide
for movement of the measuring device, an absorbing clamp.
An RF signal generator is placed on a third table.
