DIY Open-Sided TEM Cell for EMC Testing?
(1/2) > >>
coflynn:
Hello,

I wondered if anyone had designed/built their own open-sided TEM cell for basic EMC testing, or otherwise used one? Basically appears to be a few pieces of PCB of appropriate dimensions to form the cell.

As a reference here is a few examples of what I'm talking about:
Commercial small TEM cell - $599, see manual for details
Atmel article on TEM cell - fairly large
Paper on DIY TEM cell - medium size

I was looking at making PCB design that could just be sent to fab, but wondered if someone else had done that? The $600 TEM cell isn't a terrible deal compared to the cost of large PCBs, but it's also maybe a little small for my use.

Regards,

One of these days I'm going to do something like that.  But why use PCB?  I was thinking cardboard, aluminum foil and tape!

I would like to build a closed tem cell for emc radiated and susceptibility testing.  I always thought a open tem cell was some what compromised I.e spewing out e fields and picking up back ground noise.  Any one have any experience with these?

would agree, should be closed. am interested as well, so anybody who has done that and wishes to share info would really be appreciated.

I Have collected a number of papers including research on the topic however i have not had any time to review or do anything about it as i am seriously tied up with work.
PM me if you are interested in a copy of what i have collected.
