EMC RF Anechoic Test Facility Tour - EEVblog #202

[11kungfu11]

should cut a fart. I would.

[Kalkaekie]

Very interesting !! Thanks.

[mokmo23]

I found it funny to hear some cellphone signals at around 34:30, the door was probably open but that little phone must be screaming its mind off to the antenna...

[aptsys]

We have one of these at work. It sounds really odd when you walk in especially when you are talking to someone.

[FractalDistortion]

I been in smaller anechoic rooms. The local EMC test facility is a 3m chamber with an OATS. The problem I have had is there is an FM radio station down the street! It takes a long time for them to remove that noise from our scans when testing Class D amplifiers.

[shiftplusone80]

stupid youtube unsubbed me from you somehow >=/

[Macka007]

I find it interesting that they went for anechoic when a reverb with a stirrer would probably be much cheaper.

[vk2zay]

Drool at the R&S 40 GHz SA!

[TheAdambee7]

worked around these when i was in the aircraft TCAS and GPS systems business. nice chamber.

[kiyotewolf]

omg you did sound effects when the door opened,.. ha ha h!

[heroineworshipper]

That guy even looks like the Verizon wireless guy. Wonder how he ventilates the chamber, especially from exhaust.

[sixstringmania]

what are those cones made of?

[Macka007]

@sixstringmania a poorly conductive material. They have to be resistive so they can convert the the RF into heat.

According to wikipedia a mixture of carbon and iron is very common. I think I have heard of silicone being used (I guess it would have to be silicone and some other material to be able to do the job)

[AntiProtonBoy]

Interesting how the sound changes too as you enter the chamber.

[luisramos123]

Jesus, could you two be more awkward?

[Gameboygenius]

Joking around about which frequencies are DC... Har har! EE humor!

[TheEPROM9]

In the university I go to there is a chamber like this for testing arials built by students working on wireless technology. Greenwitch university is it.

[TheCrazyInventor]

It sounds like the guy you were interviewing didn't really want to be there... Interesting info in this video (I have never seen this kind of equipment before... And that anechoic room.......) but the video was overall a bit boring.

[TheBigMclargehuge]

What's mulletry teesting?

[lazerusmfh]

No offense to that guy, but man he sounds boring! And no, not you Dave! Thank you for your H.R.T.

[CampKohler]

When that door opened, I expected to see lots and lots of eggs.

[toddrharrison]

-_-  Zzzz...

[ivaneduardo747]

Apple used one of those chambers to test their (bad) iPhone 4's antenna reception.

[thefekete]

The Ferrari: Don't turn it on... Take it apart!

[Photonface]

That's one hell of an Iron Maiden

[mathtek1]

I want my garage fitted with those cones, and my bedroom as well. Hell, make it the bathroom too.

[avalon449]

Awesome!

[electrodacus]

Good video.

The one where I used to work was similar in size to the one at minute 30:30 also the cones where sponge but covered the entire room.

I was testing my airbag control unit so automotive.

I strange to be inside the sound is not reflecting.

[fingerboy18]

That second room looked like CGI haha!

[Objuice]

Thank you so much for sharing this Dave!

[ElektroHut]

Jesuzz is this a movie or an RF lab tour? WTF

[rapsod1911]

When are you going to tear-down the Keithley instruments (fA and nV), Dave?

[EEVblog]

@rapsod1911 When time permits, things are hectic at the moment unfortunately.

[TrueBlueAustralian]

Is that a state of the art cassette radio there..

[bcsupport]

Dave, you would make a great a TV Show host !!

[bcsupport]

Ahhh, nice music, cool.

[motanuldanila]

The phone keeps on searching for a cell. You can hear this in the video. So the chambers are working :-).

[bcsupport]

@motanuldanila That happens to me inside an elevator, doesnt take much !

[KTecSystems]

Amazing!!!!

[rapsod1911]

Who cleans that room?

[EEVblog]

@rapsod1911 Damn, good point...

[PirateRadioPoland]

@EEVblog Sure he (or she) earns hell of money for that work :)

[thewii552]

20:58 GSM interference...in a shielded room...

[EEVblog]

@thewii552 Someone had their phone with them obviously.

[thewii552]

@EEVblog I wander if they got a signal. ;)

[jpelczar]

Dave: do you drive SUV now ? ;)

[artifactingreality]

i really like the video dave but wow you and that guy make an awkward pair.

[DanFrederiksen]

good stuff.

here in northern Europe the bastards require us to test radio emissions if we convert cars to electric drive which pretty much prevents any cars being made because the tests are hardly free and the sites are few and far between.

here in Denmark we have to go somewhere in Germany to get it tested.

[Macka007]

@DanFrederiksen In Australia all cars must be EMC tested.

[JumperOneTV]

@depomb I want room of that size for my lab. And for my gym too..

[EEVblog]

@JumperOneTV Yeah, indoor climbing wall and trapeze set in the lab would be cool!

[kkpdk]

I am surprised not to see a handler inside the GTEM. Nice to have.

[kolrabi]

Now that is a big door!

[First2ner]

man, sound inside is far better LOL

[msichal]

And remember, wear protection!

[jimarcin]

woohoo
