15.2 Block Diagram of Test Setup
15.2 .1Test Setup and Test Procedure
Table top EUT
The EUT was placed on a 0.8m high wooded table, standing on the ground reference
plane 2.6m by 1.8m in size, made by aluminium 0.5mm thick.
The distance between the EUT and any other of the metallic surface except the GRP is
greater than 0.5m.
The main lead excess than 1m is gathered into a flat coil with a 0.4m diameter and situated
at a distance of 0.1m above the ground reference plane to insure the distance between the
coupling device and the EUT were 1m or less.
The EUT was arranged and connected to satisfy its functional requirement and supplied by
The coupling-decoupling network (Best EMC).

Floor Standing EUT
The EUT was placed on a 0.1m high wooden support, standing on the ground reference
plane 2.6m by 1.8m, made by aluminium 0.5mm thick.
The distance between the EUT and any other of the metallic surface except the GRP is
greater than 0.5m.
