The EUT was placed on a non-metallic support by 0.1m above the lower
conductor in the center of the stripline.
The wanted signal was fed to all input terminals respectively .The unwanted
signal is fed to a matching network of the stripline.
The ground connection of the mains filter(M) was directly connected to the
jacky.
All unused input/output connections on the EUT were terminated and
shielded with the proper resistance.
The power supply to the mains of the EUT was attached to the mains filter(M).
Ferrite rings for this test was required on all test cables inside the shielded
room.

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.
