Really cool that Raymond EMC understands your audience well enough to sponsor their niche commercial/professional product(s) on arguably a more consumer focused tech channel. They get that the nerds behind the companies/organizations that want their products watch your content and can have a big sway when it comes to acquisitions.

[@RodrigoTonin]

well, Linus spitting terrible reviews about products will make the companies need to do better testing and probably get better equipment for doing it... and what better equipment than the equipment on the test you just failed. it's a win win situation. For Linus, For us and for the sponsor.

Been around these things too many times. If you think this chamber itself is something worth then think again. Kudos for business acumen of this company installing this chamber for free 😂 this is like drug dealer giving you first time free. Only accessories will set you off hundreds of thousands like all rotational tables, myriad of antennas, etc… then all equipment which will probably take few mil. And then salaries of people who actually know what they are doing. This is the reason why you don’t see this kind of setups even in very wealthy companies. All is nowadays outsourced to specialist certification establishments.

But the video will stay up for a long time, it will show up quite high in search results, and if techies want to know more about EMC they might watch the video if their company is starting to feel a need for such equipment. And then they see the name of this company. It's a bit of a deep investment but yeah I can totally see why Raymond EMC would do this.

[@fitybux4664]

Anyone who makes any kind of electronic product whatsoever should be saying "oh yeah I can use that". Or, "oh yeah, we rented one of those". (The more likely case.) Yes, ALL (read: ALL!!!!) products should be EMC tested. However, sometimes they are made in China and violate this. Or sometimes they don't have any kind of RF receiver/transmitter, and the manufacturer is like, "eh, screw it we don't give a damn". But, unintentional radiator emissions is a thing.

[@pirojfmifhghek566]

Those two people, if they're in the market for it, are the kinds of people who have probably been tearing their goddamn hair out looking for a company that can just do this one goddamn thing correctly. And seeing it done correctly is often a lot more than you tend to get from most businesses like this. Usually you get a spec sheet, some technical video full of roses and spit polish, maybe a written review from somebody you've never heard of... that's it. Industry folks usually figure out which companies to hire based on who their peers are hiring. In competitive industries, they'll even keep that info secret because they don't want anyone else knowing about their suppliers. So a sponsorship like this could mean bagging some big clients.

[@jonasharp3]

This whole lab setup is going to be absolutely massive for consumer tech. With the industry being more complex and harder for the layperson to understand everyday, it’s also easier than ever for dubious claims to go unnoticed, and realistically not that many people without field specific expertise were asking for something like this. As an audio nerd I was giddy to see you buying top of the line measuring tools, but this is something I wouldn’t have even considered an option before today. It makes me excited to know someone is out there with the intent to put the claims of tech companies through rigorous analysis, and hopefully foster a culture of transparency and accountability in the tech industry.

A14245, for the simple task of protecting equipment from an EMP or solar event, will a basic grounded and sealed metal container do the trick?

[@ccoder4953]

@@Spushed Honestly, for most of that, just unplug any external cables and disconnect any antennas and it'll probably be fine. If you want details, well, they're actually a little hard to find precise details on what an EMP actually looks like and you start running into needing actual RF test equipment to figure out how good your enclosure really is. Also, exactly how bad an EMP will be in your precise location is a REALLY complicated question, even if you have the rest of that. RF engineering isn't called black magic for no reason - things like geometry, materials, and a whole lot more matter alot. A metal container will probably help (assuming it has no wires running in or out) enough, but most devices are designed with quite alot of tolerance to damage from high frequency RF. It isn't done for EMP protection, it's done for electrostatic discharge and EMI regulations, but for an unplugged device during EMP, that's really the parts you worry about. The low frequency parts of an EMP are mostly a worry for stuff with long wires or connected to the grid (which is long wires) which can act as antennas at those frequencies.

My only rule for a router is no Broadcom chips as Broadcom has bad support for things like OpenWrt. I found a nice Qualcomm router which might I add is very overspeced called the DynaLink DL-WRX36, it is a WiFi 6 router with 1, 2.5G WAN port, a quad core Qualcomm IPQ8072A, 1GB of ram (doesn't sound like a lot but many routers have wayyyy less than this), 256MB Flash (again, might not sound like a lot but many routers have less), has OpenWrt support and have been running it stable for months on that (even though it is still on a snapshot release), the only caveat is that I would not trust the default firmware that comes with it just because the company is unknown so I would recommend installing OpenWrt and the most important thing (yes, even more important than these overkill specs) is the device uses Qualcomm and not Broadcom, I made the mistake of going for an Archer AX21/AX20/AX1800 (yes, Web UI, UART, and sticker on the bottom all said different model numbers) and it was painful, Dynalink has been working beautifully

Former USAF metrologist here. I did almost 20 years of metrology with 12ish years being in RF metrology. 100K for a portable spec an with reasonable specs is a pretty damn good deal. But we were doing stuff up into the 50Ghz range by the time I medically retired which kept our unit costs substantially higher.

[@ccoder4953]

Yeah, it's gotten pretty reasonable (for that sort of equipment). If you need 50GHz, Keysight has portable stuff that starts at $70k that can go there. If you don't need those kind of of frequencies, Siglent has some very well reviewed equipment, some of which is actually affordable to hobbyists (decent gaming PC sort of prices). And there's alot of newer equipment that isn't like the old boat anchors - it might not be a battery powered portable, but it's easy to pick up and move with one hand.

[@tonymorris4335]

@@ccoder4953 yeah our issue was always the accuracies that we needed... frequency response/flatness was a specific one that was always tough when you went cheaper and more portable. Putting our consistent -10 DB signal in and then checking it you know every 200 meg they would all drift really badly at some point or another in the spectrum. If you just need one to do basic checks and looking for harmonics or signals you can get away pretty cheap. We rarely needed absolute RF power accuracy because every test we did needed an accuracy that required us to use a thermistor or power sensor but then we had to rely on the s accuracy to verify a signal generator all the way out to fifty for example. I'm guessing that these guys don't really need too much absolute accuracy since they only have one analyzer and they're not calibrating signals, only measuring for relative values. If they're off by three DB and measure - 30 instead of - 27 it's not going to change the outcome of their review when the other phone they're comparing it to would also be 3 DB off at the same frequency.

As someone who works with this equipment on a daily basis. Thank you LMG for letting me view my work after work. Still learning every day. One thing i'd like to learn more about is Passive Intermodulation testing and how it can affect antenna.

[@bjarkeistruppedersen8213]

That is a sponsorship that makes sense for everyone. You get a chamber, and they get tons of exposure even going forward 🙂

[@aaronperl]

Please continue doing these types of more technical videos about the lab build. They're very interesting.

[@AMalas]

That freaking cool. Ray EMC has maxxed out respect

[@SuperAdjusted]

the commitment to science dwarfs other review channels, i have no idea about most of what you are talking about but the fact that you are going into the detail, regardless of who understands, is such a hallmark of professionalism and enthusiasm. well done chaps, keep up the good work, always enjoy your videos!

[@tristanxxxx]

I agree Jamie. The great thing is that anything we don't understand, we can just pause the video and look up. I didn't know what I didn't know about this topic until I watched this video. Now I've got some reading to do, but it's great, because I know exactly what I want to research!

[@jtadevich]

These are my favorite types of videos from LTT. I'm a science nerd with an RF engineer father. Right up my alley. I'm glad he loves his job. It makes these videos really good. I'm really glad you didn't sell.

[@akwurd]

I love being a nerd and getting excited about this stuff. Also watching you get excited about stuff makes it that much better

[@antibrevity]

"Assuming that anyone ever actually starts caring about cellular signals that can be blocked by a piece of paper." Love it.

[@ThePwig]

First time I’ve seen LTT actually taking about something I do every day in MRI rooms and other shielded applications. These types of rooms have other uses for EMP shielding for extremely important and sensitive installations that you can imagine but I can’t explicitly say.

[@Mainyehc]

Ooooh, someone has a security clearance and/or is under an NDA 😏

[@charlesenfield2192]

This was interesting. I do enterprise WI-Fi for a living and tried the rig up some test apparatus from stuff I had laying around. It was a bust. I speculated a number of reasons for the failure, but wasn't confident about any of them. Your explanation confirmed quite a few of my theories, and illuminated a couple new ones that I hadn't considered.

[@oddball_the_blue]

That's so much bigger than our works desktop mounted RF box (we use it to test development cell networks). Massive overkill... very, very Linus. Keep up the good work.

[@angelofasuna1282]

As an EMC Engineer! i’m super glad that i saw this video!

[@InBetweenHonor]

I hope the editor had a good weekend and plenty of enjoyable moments with their games. You do wonderful work!

[@spdcrzy]

Man, I'm gonna miss LG. Their phones were legendary for having really good reception - BACK WHEN MEDIA OUTLETS ACTUALLY TESTED THINGS LIKE THAT! I can't wait for Linus to bring back that sort of real-world capability testing to tech media. We've been relying on specs for way too long.

[@zyonbaxter]

Mega Shout out to Robert Oakes the Editor who did an amazing job on the fine print.🥳 And of course we do enjoy reading the fine print and all of your other Easter eggs.😊 You'd be crazy not to observe them with the wonderful effort that you're putting in and with the way things are in the world. P.S. I'm so glad KZbin finally lets you magnify videos. It's still blurry but that's better than nothing.😅

[@MindlessDude]

Glad I'm not the only one who took the time to pause and read it. Like a small club of nerdiest nerds.

Great to see, I have previously performed and published TRP and TIS antenna performance comparisons of many phones. Looking forward to see your results, also guessing you will not spec it for 3gpp MIMO OTA testing.

[@pufthemajicdragon]

I'm just here to let the editor know I read their fine print. Thank you, editor, for such fine quality content.

[@thegreenmadow]

The editor did an especially great job at this video :)

[@talkanything3031]

I'm not sure I'd say the editor did a "great" job, but they definitely did a fine job. The finest!

[@pauleymuthni9346]

[@realBruchpilot]

Love the fine small details from the editor - and the chamber is also fine, nearly as impressive.

[@barrettshannon9876]

Gotta love the editor of this video, I may or may not have paused the video and cranked up the zoom part way through. Have fun gaming this weekend, hope Diablo has been a blast!

[@KingAgonized]

I make RF cables and I get to use one of those spectrum analyzers. I never thought I’d see someone else using one let alone Linus. Cool.

[@robertc.9503]

I'm just surprised they let him handle a $100,000+ tool... Maybe it has a really good drop rating? 😅

Unbelievably well done. Good work raymond and ltt. Lookong forward to seeing all kinds of antenna and cellphone test results comming out of this thing.. ltt is still king of tech after all these years

[@PerryCS2]

this is what I LOVE about advanced topics... to the normal citizens they think derp derp... just put metal around it... but as anyone who knows physics understands and comprehends things are vastly more complicated than they appear on the surface... to be done properly... :)

[@TheMarkJoergensen]

Why yes. I was just looking for a properly built EMC to go in my living room!

[@Illumas]

As excited as I am for the product that will be extracted from Labs, these behind the scenes, building the lab videos, are ones I'm always excited for.

[@dahlia695]

There was a chamber like that where I used to work and the panels on the walls with the pyramids were made of thus conductive foam and had the effect of muting sound as well as electromagnetic waves. Walking in and closing the door it was so abnormally quiet that my ears would actually hurt.

[@oderbang]

You should definitely put GIANT logos of the companies that gift you these items on the items so they can be in the background of future videos!

[@lachychops2]

If there's a logo, it should also include 'donated by' or 'gifted by'. In this instance, the enclosure wasn't gifted, it was the cost of the sponsorship

[@MrCodyminner]

​@Macree I highly doubt they gifted the whole chamber for the cost of 30 seconds of sponsorship. In linus video where he talks about how much LMG makes he gives the average cost of a sponsorship. That chamber probably cost 50× the cost of a sponsorship. They probably gave him money off the cost but who knows. Maybe sponsoring a LTT video is now the same price as a superbowl commercial

[@itmeurdad]

​@@MrCodyminner ​@Cody Minner LMG is a $100m company, after all. Their influence is tremendously valuable, even for partners in a B2B space. This video has a million views in 12 hours. Unlike the Superbowl, that's a highly engaged, very tailored audience. Scroll the comments and witness the tremendous goodwill they've fostered.

[@lachychops2]

@@MrCodyminner all it would take for a decent ROI is 10-20 people that need this sort of enclosure to be in the ~1,000,000 viewers 🤷

[@Sarcastitonea]

@@lachychops2 1/100k people is a ridiculous assumption for the market of rf chambers. if this was the roi companies like this got on advertisements, there would be... 3500 of these chambers in america, or almost 300 per state

[@radicalxg8282]

Few tech labs have such a thought out sofisticated and dedicated EMC cage you guys and the raymond teams are crazy!

[@ccoder4953]

That's actually pretty typical for engineers working on RF stuff. I work for a major semiconductor manufacturer and alot of our facilities have a room like that. It's essential if you're designing RF chips and want to get good measurements. Your typical tech KZbin channel won't have that, but rooms like that are more common than you might think, at least if you're in the tech industry.

[@pixelmaster98]

@@remeuptmain you're commenting that same sh*t everywhere, yet nobody asked you for that, either. So I *am* going to ask you something, and that is to shut up, please :)

[@pedro4205]

@@ccoder4953 A major semiconductor manufacturer isn't exactly a typical company. As a matter of fact, there aren't even dozens of them.

[@ccoder4953]

@@pedro4205 There's more than you think, you've probably just never heard of most of them. We don't normally sell to consumers, we sell to other companies who put our chips in your products. So you'll probably never hear about Skyworks, Semtech, Navitas, Richtek, Nordic Semiconductor, Silicon Labs, Microchip, Renesas, and many others. Not all those are "major", but many of them will have an RF room for doing either RF testing or EMI validation. I myself work for Analog Devices, who is a major semiconductor manufacturer, but not exactly a household name (even though you almost certainly own products with our chips in them). Even back when I worked for Linear Technology (before the acquisition), several of our facilities had rooms like this and LTC was sort of a medium sized company.

[@sophiophile]

​@@pedro4205 These rooms have lots and lots of niche uses. MEG (a really cool method of recording brain activity) uses a room like this *AND* a beehive shaped thing on your head filled with liquid helium cooled material for even more intense shielding.
