The capacitance value should be calculated from: Shipping Delivery Order tracking Returns. Typically the driven side crystal XTAL is of a higher value. Identify specification and revision number being used. DUT face with connectors perpendicular to coils, harness parallel to coils.
It is easier and cheaper to remove the provisions later if not necessary based on testing than to add them. This will depend on both the hardware and the software. Duplicate entries for input names may exist under different modes. Identification of fundamental operating frequencies: This may require special software to decrease the data rate to be within the bandwidth limitations of analog fiber optic transmitters.
Resources needed for a successful EMC design review other specialists, engineers, purchasing or managers depending on situation and complexity.
We wish you a pleasant end-of-year holiday. Specify if DUT is accessible from outside the vehicle. Use the smallest capacitor that will do the job. All open spaces on outside layers should be filled with ground plane. Any deviation from the approved test plan and any applicable standards, including, but not limited to, test setup and test procedure.
Providing separate power feed structure to main? More inductors and capacitors may be needed, and at different values. Connections between transient generators, monitoring equipment, and the DUT.
Table A4, shown below, should be used to provide this information.
If this motor is in a corrosive environment, such as washer fluid, exposed to salt, etc. Use SMD components with very short traces to the return plane. Rubber and plastic industries Actual hardware samples or physical mock-up for visual examination is desirable but not required. List all individual pins, case discharge locations, discharge type, simulator voltages, discharge network type and a description of the pin signal.
The supplier is required to submit the applicable validation test results in the format 3013 by the authorized test laboratory in their entirety without modifications. Part number and description of the harness.
This information is taken directly from GMW for those items relevant to the lab. General Theory of Operation inclusive of how it is used in the vehicle.
More detailed appendices for design review and test plan. Include mode information for each entry.

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. The product qualified for a prior program and is exactly the same product being used for the future program. All sections shall be included as stated in the outline, only additions of new sections 3130 allowed.
Keep high speed lines within inner layers, placed between power and ground planes if possible. Zener Power Supply B4. B3 Interface Connector and Cables B3. Description of the test setup and equipment used. Modifications, alterations, internal part swaps, hardware and software changes are not considered carryover and must be validated according to the requirements. Initial EMC test results shall be studied and reviewed, and if not available, identify when review of test results can be done.
For this situation, the motor case shall be connected to the motor winding via a small ceramic capacitor 1 nF, typical. Photographs with sufficient clarity to enable compliance with the test plan to be verified.
Provide output voltage and current time domain measurements 303 power outputs and inputs. Brief family description of DUT s. These ground “islands” need to be tied to the ground plane with multiple vias or many short, ggmw low inductance traces connecting them all together. Part Number contains common electronics with
