• The DUT shall be powered from an automotive battery (see paragraph 4.5.4 for requirements). The battery negative
terminal shall be connected to the ground plane. The battery may be located on, or under the test bench. See Annex G
regarding the standard test Setup for the Load Simulator, battery and Artificial Networks.
• The test harness shall be 1700 mm (+ 300/- 0 mm) long and routed 50 mm above the ground plane on an insulated
support (ε
r
≤ 1.4) over the entire length between the DUT and the Test Fixture.
• The test bench shall include a sufficiently large ground plane, such that the plane extends beyond the test Setup by at
least 100 mm on all sides.
• The distance between the test setup and all other conductive structures (such as the walls of the shielded enclosure)
with the exception of the ground plane shall be ≥ 500 mm.
• The test antenna shall be mounted above the DUT and parallel to the ground plane. The DUT shall be positioned to
ensure that the surface under test is facing the antenna.
