Did your product fail FCC testing for radiated or conducted emissions testing? I have 15+ years experience in power electronics and RF design. I would be happy to consult with you for a reasonable rate and can come on site if needed to help make last minute tweaks to your design to get you to pass EMC/FCC testing. I am based in the USA and am a native English speaker

I am experienced in a variety of issues that are commonly found during EMC testing including common mode conducted emissions, radiated emissions up to 24GHz, filtering for leakage out of displays, star ground concerns, shields and shield windings for transformers, and conducted emissions for power supply inputs and outputs. I can also help with emissions from high speed data ports such as USB 3, HDMI, etc.

I have RF signal generation and spectrum analysis equipment that can help in quickly locating the source of problematic emissions. I would be happy to take a look at your PCB and enclosure design to check for issues before FCC testing to save you time and money.

If you are designing a product that connects to the mains for power I also provide consulting and design services to review creepage and clearance requirements to make sure you pass UL and CE safety testing as well as HiPot testing.
