Re: EMI Testing

2005-02-21 by fl429

Actually, I have a 2x2x2 cu ft grounded mesh enclosure. I was 
thinking about using it as the "clean" area to place my board in. I 
admit I have never done something like that myself.

We have been using a third-party lab to do our testing. I am 
wondering if I could put something simple together so that by 
comparing test done in the past by "expert" lab and now my own jig 
that I can get a rough picture of EMI of my future boards before I 
send them out to an external lab for final testing. 

Is that too much to ask ?!

Thanks
