e) Repeat step d) with antenna rotated 90 degrees
f) Repeat steps (d) and (e) until all cells have been exposed. When testing DUTs with multiple cells, centers of some
cells will be exposed to the elements of the antenna while performing steps (a) to (c) to the adjacent cell. In such
cases, it is not required to carry out steps (d) and (e) that would result in a duplicate test. If there is any doubt over
effective exposure of cells to the elements of the antenna, steps (d) and (e) shall be performed.
g) Repeat steps a) through f) for each DUT surface defined in the EMC test plan. Testing requires rotation of the DUT
such that the surface to be tested is parallel to the ground plane. Low permittivity material shall be used to support
DUT so that the surface under test is facing up toward the antenna.
11.6.2.2 Antenna Positioning for Coupling to Harness
Position antenna central to the connector under test and parallel to harness. Align the center of antenna with the outermost
edge of the DUT connector. Expose DUT to test signals specified in table 11.4. In cases where DUT has multiple connectors
or connectors are wider than required cell width (30 or 100 mm) test shall be repeated multiple times.
If deviations are observed, the power shall be reduced until the DUT functions normally. The power shall then be increased
until the deviation occurs. The power at this point shall be reported as deviation threshold.
