A complete electrical schematic of any and all terminations on each of the DUT circuits within the load box connector s to the DUT e. Documentation required to be delivered, as one package, to vehicle manufacturer EMC design review team at least 10 working days gm of the scheduled meeting: Route clock traces between power and ground planes if possible.

Resources needed for gnw successful EMC design review other specialists, engineers, purchasing or managers depending on situation and complexity. For this situation, the motor case shall be connected to the motor winding via a small ceramic capacitor 1 nF, typical. F, whichever is greater.

Zener Power Supply B4. Fluid systems and components for general use Rubber and plastic industries Identify specification and revision number being used.

B2 Printed Circuit Board B2.

The complete series consists of the following documents: The simulators shall be in non-metallic housings and isolated from the ground plane. Module-to-Vehicle Electrical Interface Analog Input Ggmw 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.

Packaging and distribution of goods If there is only one ground wire, it should be located at the center of the connector. Use only low ESR capacitors. Conductive gaskets are recommended if: Do not choose a large value of capacitor.

Identification of fundamental operating frequencies: If this motor is in a corrosive environment, such as washer fluid, exposed to salt, etc. Keep high speed lines within inner layers, placed between power and ground planes if possible.

There should be at least one bulk storage gma on the PCB.

Connector pin assignment is important when working with twisted harnessing. All electrical and non-electrical inputs excluding the DUT connector sidentifying what they are and whether they are to be 31103 by the supplier as part of the simulator package or whether it is expected that the EMC test lab provide them. Use SMD capacitors with very little to no trace length to ground.

Construction materials and building All of the pins should have 1 nF to 15 nF capacitor that will not affect proper functionality.

P on all traces leading to test connectors, to facilitate removal after product development is complete, reducing the radiated emissions risk. Module-to-Vehicle Non-Electrical Interface RF Link s These are typically pressure sensors, fuel-type detection, opening-and-closing mechanisms and stops, etc.

Use SMD components with very short to no traces to the return plane. GMW 6 Notes 6. User Interface These typically include display panels, gauges, feature selection buttons, backlighting LEDs, etc. PCB to Case connections may need to be made only near gmq vehicle interface connector, not at all 4 corners. Any DUT monitoring equipment located outside test chambers and bmw connection through chamber walls. The complete series consists of the following documents: Minimize all traces to be as short as possible.

These ground “islands” need to be tied to the ground plane with multiple vias or many short, thick low inductance traces connecting them all together. The supplier is required to submit the applicable validation test results in the format provided by the authorized test laboratory in their entirety without modifications. Suppression device, typically a diode or metal oxide varistor MOVshould be referenced to ground with shortest path as possible.

Tables A7, A8 and A9 should ggmw used to provide this gms.

This may reduce radiated emissions. Also, provide justification for any omissions in testing for any of the DUT test modes listed. Nothing in this standard supercedes applicable laws and regulations. The connections between the battery and the artificial networks AN. All open spaces on outside layers should be filled with ground plane.

Date s of test for each test performed. For development reports, a watermark that does not obstruct data is preferred. Only the latest approved standards are applicable unless otherwise specified.

Add appropriate ESD protection transorbs, back-to-back zener diodes, series inductance, RC filter, etc. Part Number contains common electronics with EMC Test Reports if available. Traces are required to be symmetrical to each other or balanced with little trace length. Using screws, fasteners or other forced contact methods.

For data buses, gwm may mean splitting the capacitor value between devices. The bypass capacitor shall be connected directly to the ground plane through the lowest impedance path. A plated thru-hole on a printed circuit board to route a signal between layers.
