Typically the driven side crystal XTAL is of a higher value. Examine any prior relevant analysis, calculations and test results.
3130 This requires specific prior agreement by the vehicle manufacturer’s EMC engineer, and shall be documented in Table A2. HS or Digital traces or reset lines should be kept 2.
The cost of meeting radiated emissions is increased substantially due to possibility of having to contain the emissions with the addition of shielding the case and possibly filtered connectors.
Initial EMC test results shall be studied and reviewed, and if not available, identify when review of test results can be done.
Module-to-Vehicle Electrical Interface Analog Input Shall be set nominally to the mid-range input value 31033 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 bypass capacitor shall be connected directly to the ground plane through the lowest impedance path. If this motor is in a corrosive environment, such as washer fluid, exposed to salt, etc. Diodes can rectify RF. List all product part numbers that this test plan is applicable to. Field Effect Transistor FET devices may be capable of surviving these transients; however, bipolar devices will require extra protection e.
Include mode information for each entry.
Bonding of the transient generator to the ground plane. Specify special test arrangements that apply to this test. Access from Inside Vehicle Cabin? All connections to power and ground planes have to be very short runs – Pin To Plane with low inductance paths g,w the tester is current starving the IC, refer to B2. The supplier is required to submit the applicable validation test results in the format provided by the authorized test laboratory in 3130 entirety without modifications.
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.

If a section is not applicable, this shall be stated in the document after the relevant section description. Shipping Delivery Order tracking Returns. List all DUT test modes and the input names used in them. The connections between the transient generator and the capacitive coupling clamp. Glass and ceramics industries The term carryover means 303 the product qualified for a prior program and is exactly the same product being used for the future program. Turn off via software any and all?
Documentation required to be delivered, as one package, to vehicle manufacturer EMC gma review team at least gmww working days ahead of the scheduled meeting: Unless otherwise specified in the EMC Test Plan, in order to ensure a refreshed value, all information related to data monitoring such as analog input voltages, operating states, etc.
Use SMD components with very short traces to the return plane. Refer to manufacturers’ recommendations.
General Theory of Operation inclusive of how it is used in the vehicle. An electrical circuit diagram is preferred. Refer to Figure A1 in Appendix A. This includes directly accessible faceplates, displays, and remote buttons and test connectors. Use only low ESR capacitors.
Electronic documents must be in an editable format compatible with Microsoft Office. Add appropriate ESD protection transorbs, back-to-back zener diodes, series inductance, RC filter, etc.
Care must be taken to ensure functionality, such as oscillator startup.
