6.8.4 Test Setup
Note:
TABLE-TOP EQUIPMENT
The configuration consisted of a wooden table (0.8m high) standing on the Ground
Reference Plane. The GRP consisted of a sheet of aluminum (at least 0.25mm thick
and 2.5m square) connected to the protective grounding system. A minimum distance
of 0.5m was provided between the EUT and the walls of the laboratory or any other
metallic structure.
