G120 radiated emissions- 36dB per millivolt at 60 MHz


#1

I’m wondering if anyone else has looked at the radiated emissions of the G120 module, seen the spike at 60MHz of 36dB per millivolt, and found a way to fix it?

How are you measuring this? Is it conducted or radiated emissions you are measuring?

On my design I only tested over the 150Khz to 30Mhz for the normal EMC testing range so I would not have seen the 60Mhz signal you are seeing so if I get time today, I’ll hook up the G120 board to the spectrum analyser and see if I see the same at 60Mhz.

Thank you for the quick response, I am looking at radiated emissions. If someone else is seeing this, we might be able to entice the fantastic and highly supportive team at GHI to take a look at suppressing it.
