we have several PCB boards which were detected as a source of 100MHz emission in the lab. We would like to find the source of this signal with our spectrum analyzer(Siglent SSA3032X).
we have probes and did some tests already, but it's hard to find anything useful since it's a new experience for us and we do not even know where to look.
We need someone who has BIG experience in such troubleshooting and be able to spend 1-2 hours with us debugging the board and guiding us over skype video call.
You should really teach us the technique of finding EMI issues and find the problem to get payment.
