Customers sometimes ask me “what EMC pre-compliance equipment should we buy?”
My reply is that I’m more than happy to help them spend your equipment budget!
Here’s an email that I sent to a customer recently when they were asking for feedback on some test equipment that had been proposed to them
A good spectrum analyser is pretty indispensable when it comes to wrestling with EMC issues. The Siglent ones (available from I4E and Telonic) are pretty damn good for the money, I’d buy one if I was in the market.
I have just written a free ebook on the subject of near field probing which might be of interest.
Challenges with on site pre-compliance measurements
- Dealing with background noise (near field probes and current probes are pretty resistant)
- Relating levels it to a formal measurement standard (not possible)
- Interpreting the results and figuring out what to do about it (expert level!)
If you decide to go down the road of getting your own equipment I’d be happy to come up and do a day with you running through measurement setups, tips and tricks if you think that would be helpful.
Alternatively, if you want to make some antenna based on-site radiated measurements I can come up and do a day with you with our spectrum analyser and portable antennae.
