Mining and minerals GMW to be filled by supplier, enlarge this area as necessary?
The connections between the transient generator and the capacitive coupling clamp. Use resistor dividers, not diodes, to set reference ggmw when necessary. Provide graphical picture showing discharge locations. Health care technology Dynamic cycling required between asserted to non-asserted, back to 31103 states during radiated immunity RF “on” exposure, verified using direct monitoring with fiber optic system or using “loop back” method e.
Description of the test setup and equipment used. Dynamic cycling required between asserted to non-asserted back to asserted states during radiated immunity RF “on” exposure, report directly by communication or indirectly via output state change by detected input e.
Denotes a binding provision; a must. Include any additional information required to support DUT operation during test, including data bus messages, and special test software. Multilayer boards are always recommended. Facility name including the test site designations where the tests were performed. Gme special test arrangements that apply to this test.
Nothing in this standard supercedes applicable laws and regulations. The supplier is required to submit the applicable validation test results in the format provided by the authorized test gkw in their entirety without modifications.
All electrical ground connections shall reference the DUT-side output terminal of the artificial network in the ground circuit. The complete series consists of the following documents: Module-to-Vehicle Electrical Interface Analog Input Shall be set nominally to the mid-range input value and value reported either directly via the DUT communications bus or, indirectly through the DUT monitoring the input and changing the state of an output in a known, pre-determined manner e.
Construction materials and building F Linear Power Supply. Actual hardware samples or physical mock-up for visual examination is desirable but not required. Provide for adding series ? These inputs typically apply to the simulator only, but some simple devices, such as DC brush commutated motors, may not require simulators, shall be supplied either within the load simulator, by support equipment provided by the supplier, or by the EMC test gms.
Begin with 22 pF to 47 pF capacitors, increase until sinusoidal waveform is achieved. General Theory of Operation inclusive of how it is used in the vehicle. All high-speed control rise and fall times should be minimized or slowed down as much as possible.
Use SMD components with very short traces to the return plane. Provisions for current starving the? Route clock traces between power and ground planes if possible. It describes all relevant test setups and procedures to verify the electromagnetic robustness of the design. If there is only one ground wire, it should be located at the center of the connector.
All connections to power and ground planes have to be very short runs – Pin To Plane with low inductance paths unless the tester is current starving the IC, refer to B2. These test modes and functional performance metrics shall be detailed in Table A3.
Provide pads and space for capacitor s to ground on each trace located at the source end s.
Specify other special test arrangements that apply to this test. Input capacitance must be larger than output capacitance. Paint and colour industries Alert me in case of modifications on this product contact us.
I certify that the product samples submitted for EMC testing are of a production representative design and agree tmw adhere to the CEMENT test plan and data submission milestones unless permission to adjust them is granted by the GM Design-Responsible Engineer.
Keep high speed lines within inner layers, placed between power and ground planes if possible. Avoid using expanded memory microprocessors if possible. Design analysis and performance is a part of the design review. Design Analysis and Performance.
The details shown in photographs must include, but not be limited to, those details described below as applicable for each test performed: For data buses, this may mean splitting the capacitor value between devices. Combination of digital and analog that requires bus messaging to a tmw load. The term carryover means that the product qualified for a prior program and is exactly the same product being used for the future program. Use only low ESR capacitors.

Use SMD components with very short to no traces to the return plane. Tables A7, A8 and A9 should be used to provide this information. Using screws, fasteners or other forced contact methods. Connections between transient generators, monitoring equipment, and the DUT. Rubber and plastic industries This reduces the stray capacitance between the power structure and ground structure and enhances the performance of the current starving device resistor, inductor, or ferrite bead.
The GM Validation-Responsible Engineer’s acceptance of review results and supplier action plans does not relieve the supplier of the obligation to meet contracted performance requirements.
