    33 FCC &amp; 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.

    366All 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.

    39 Below are some baseline scans for the standard Ventana SBC models in our metal indoor enclosures with a PoE powersupply. Note these are baseline scans and FCC certification must be performed on your specific system which includes any peripheral cards, cables, antenna, power supplies, etc so results will vary depending on your configuration.

     19FCC Tips

    5121Tips for passing emissions include, but not limited to:
    52 </p>
    53 <ul><li>Using metal enclosures with minimal openings
    54 </li><li>Use shielded cables
    55 </li><li>Proper grounding of the board, enclosure, cables and power supply
    56 </li><li>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.
