    2 Are Gateworks boards FCC certified?

    4 FCC & CE testing must be done on the complete system which includes enclosure, cables, radios, antenna, power supply, etc. Because of this, we do not provide FCC/CE certifications. We can however work with you on getting your complete system through certification.

     3FCC & CE testing must be done on the '''complete system''' which includes enclosure, cables, radios, antenna, power supply, etc. Because of this, we do not provide FCC/CE certifications on individual boards. Gateworks can however work with your certification house on getting your complete system through certification.

    65All of our products have been designed to reduce both conducted and radiated emissions and most customers make it through the approval process with minimal effort, assuming they have an adequate enclosure solution. We can also work directly with your certification house to provide the necessary documents for the certification process.

    12 Unintentional Radiators - Devices which don't transmit RF
    13 Example: Gateworks SBC without Radio
    14 Certification cost is considerably less than a system with intentional radiator
    15 Intentional Radiators - Devices which transmit RF as part of their standard operation
    16 Example: Gateworks SBC with Radio (Wifi, Cellular, Bluetooth, etc.)
    17 Certification is more extensive and costly to make sure the transmitted RF is within allotted specifications
    18 Using pre-certified radios (in same manner/setup as manufacturers certification) can eliminate requirement for verification of the transmitted RF and allow testing as an unintentional radiator at reduced cost
     11Unintentional Radiators - Devices which don't transmit RF. As an example, a Gateworks SBC without Radio.
     12Certification cost is considerably less than a system with an intentional radiator. 
     13
     14Intentional Radiators - Devices which transmit RF as part of their standard operation. As an example, a Gateworks SBC with Radio installed in one of the Mini-PCIe sites (Wifi, Cellular, Bluetooth, etc.). Certification is more extensive and costly to make sure the transmitted RF is within allotted specifications. If a pre-certified radios is used (in same manner/setup as manufacturers certification) transmitter testing can sometimes be eliminated allowing testing as an unintentional radiator at reduced cost. Check with your certification house for details and requirements.

    2016= FCC Tips =
    … …  
    2218Tips for passing emissions include, but not limited to:
    2319
    24 Using metal enclosures with minimal openings
    25 Use shielded cables
    26 Proper grounding of the board, enclosure, cables and power supply
    27 Use pre-certified wifi radios. By using a pre-certified radio you can avoid having to re-certify the radio which can be more expensive since it is classified as a transmitting device. Note you must use the radio in the same configuration and with same antenna (gain) as it was certified. Check with your certification house for exact rules and regulations.
    28 A handy method to view the emitting clocks on a Ventana board is to use the command:
     201. Use a metal enclosure with minimal openings. Make sure if the enclosure is painted that the paint is removed/masked in areas that come in direct contact with the connector shields. For example, the Ethernet RJ45 shields should make direct contact with the enclosure metal. Any paint in the cutout hole should be removed/masked.
     212. Use shielded cables for power, Ethernet, USB, etc. Make sure the shields are terminated at both ends during testing.
     223. Proper grounding of the board, enclosure, cables and power supply. Gateworks boards typically have several mounting holes with options to tie these mounting holes to either digital or chassis ground. There are also options for tying chassis and digital ground together. Contact support for the various options for each board.
     234. Use pre-certified wifi radios. By using a pre-certified radio you can avoid having to re-certify the radio which can be more expensive since it is classified as a transmitting device. Note you must use the radio in the same configuration and with same antenna (gain) as it was certified. Check with your certification house for exact rules and regulations.
