Our ground plane (03-00007A) is a set of three 1.8m × 1.0m plates.

Under IEC61000-4-2, the ground plane must extend at least 0.5m beyond all sides of the EUT or horizontal coupling plane, so 3m is required: 2.0 + 0.5m (right side) + 0.5m (left side).

If necessary, this can be accommodated by preparing two or more sets of ground plane (03-00007A).
