Easter picture post

Jimmy’s sent over a some pictures taken during the setup for a couple of last week’s tests. I know a lot of you were interested in seeing what the inside of an anechoic testing chamber looks like. When you’re done geeking out, scroll down to the bottom for a bonus picture from a pub toilet. (Nothing to do with our EMC testing, but it has a bearing on CE marks of more than one kind.)

Radiative immunity test - the Raspberry Pi is at the front right corner of the table. The video camera at the left is for monitoring output while we run the test.

Radiative emissions setup

Setup for testing radiative emissions. The device standing against the wall at the left is a microwave horn for receiving frequencies above 1GHz.

So: the pub toilet thing. In the last week or so, we’ve all been hyperaware of any CE marks in our immediate environment because of all the work we’ve been doing to make sure we are allowed to use one. CE stands for Conformité Européenne, meaning “European Conformity”; it’s a mark which shows that the product it’s on conforms to whatever European directives govern the product type.

We’ve been particularly interested to observe all kinds of things, electronic and otherwise, which carry a mark which looks a lot like the CE mark, but which doesn’t mean Conformité Européenne. The other mark means China Export – you can see the difference between the two marks in this picture. It’s a sneaky-clever way some people try to get around the regulations.

So I was really creeped out when I spotted the machine below in the ladies’ loo in a Norwich pub this lunchtime. Compare the symbol reading “CE” at the bottom to the ones above. (Yes, that is my glowing face reflected next to the lime. I do not actually have a unibrow; it’s lighting.)
