@ekt2018 Your most recent description is much clearer! Thanks!
Quite apparently you need that individual inside Onion that was the responsible engineer for the certification tests that got them the FCC and EU certs. For that, I don't know of the person.
I sure would like to know as well. Fortunately for me the product I've shipped is deployed on buoys in the US, so I'm clean with the FCC.
If indeed the correct person is found I wonder if they would release the certification test report to you as that may be all you need. If the FCC & EU cert tests they were required to do meet the ANATEL specs you may be golden. Now...finding the person and getting the test report.... What I mean here is if it's been tested, it's been tested. You would not need to replicate if specs are met for emission testing.
Good luck! Let me and the community know how it goes.
@Lazar-Demin Could you point us to the Onion RE for emissions testing?
