I wish there was better resources out there for OSHW project for things like EMI compliance testing, and determining if what you're working on needs it in the first place.

It's all too terribly fuzzy

@lethalbit yeah, the fact that compliance testing is expensive.and paywalled is a problem!
@kkarhan @lethalbit the dumbest thing is, you have to pay to get access to the standards you must comply with. Will (probably) never understand the intention behind this.

@Mr_Hat_2010 @lethalbit Exactly.

Compare that to mandatory #TechInspection for motor vehicles in #Germany where I can get the datasheets for what my car must have from the manufacturer as per compliance certification and only need to pay some certified testing center less than €100 to get them to verify compliance and have said test engineer sign that in lieu of me lacking mandatory certification and test equipment to do it myself.

@lethalbit oops, all antennas!
@lethalbit I just went through this in the past year, and I came extremely close to forming a compliance testing co-op with other indie product designers. I just don't particularly want to work as a compliance engineer. It's insane that you're expected to comply with rules that you literally have to pay a private standards-keeping entity to read. On top of that, you have to pay just to find out what the approved testing procedures are. It's absurd.

@lethalbit there's been a rise in the quality of hobbyist-targeted content in terms of preventing EMI issues, but clear guidance on the actual testing stuff is still hard to come by.

MicroType Engineering has some good videos on EMC though, including this one on EMC testing and FCC certifications:

@lethalbit it's still a far cry from everything you need to know to get a product through EMC and to market (especially outside the US) but I found the videos really useful as a starting point (e.g. explaining how to use a LISN for pretesting)

@gsuberland @lethalbit Not too helpful wrt EMC specifically, but I am planning to start adding protocol compliance testing wizards to ngscopeclient eventually.

I'll start with Ethernet since the specs are open.

If we can figure out good ways to do FCC etc. precompliance testing in a somewhat automated ways I'd love to add that too.

@azonenberg @gsuberland @lethalbit Conducted Emissions is pretty easy still too (and FFT properly filtered would work fine).

@AMS @gsuberland @lethalbit Just a matter of looking up the specs and making a wizard to walk the user through the test procedure.

Feel free to file a ticket so we can officially have it on the radar.

@azonenberg @gsuberland @lethalbit Will do (once I finish my dig up of legal access to test specs because some places have public standards).

@lethalbit

If it's terribly fuzzy then you probably do have an EMI problem
