The primary DUT and any electronic hardware in the monitoring DUT shall be powered from an automotive battery 12.5 to 13.5 V. The battery negative terminal shall be connected to the ground plane bench. The battery may be located on, or under, the test bench.
The battery positive connection shall be routed through the artificial network to the harness near the monitor/load box DUT. Battery positive line is then routed with the harness from the monitor/load DUT through the injection probe to the primary DUT. The artificial network chassis is tied to the ground plane.
The test bench shall include a sufficiently large ground plane, such that the test harness lies in a straight line.Spacing between the edge of the ground plane and the test harness, primary DUT, monitoring DUT, etc., shall conform to ISO 11452-4.
The primary DUT housing shall be placed on an insulated support 50 mm above the ground plane. Primary DUT signal ground return shall be connected as described in 9.2.8 and 9.2.9.
The monitoring DUT housing shall be placed on the ground plane and any enclosure electrically connected to the ground plane during the test. Monitor DUT ground return shall be connected to the ground plane.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.
CBCI: In the frequency range 30 to 400 MHz, all wires of the primary DUT wiring harness shall be routed inside of the injection probe (CBCI) as ilustrated in Figure 19B. Grounding of harness shall be made through the monitor DUT as shown.
For devices with multiple communications interfaces, each interface shall be tested separately. Only the specific communication line(s) under test, and the ground return as dictated by 9.2.8 and 9.2.9, shall be routed inside the probe. All other harness lines shall be routed outside the probe. The untested wiring shall remain as close as possible to the outer case of the injection probe. The other communication lines shall be actively communicating.SAE J2962-2 pdf free download.
