I find it funny that they brought all those RF devices to DC

@@SHDK-vq1rx It's almost like an Alanis Morissette song... "Isn't it ironic"

"Most people already owns a SMW" - not sure what people you are talking about :D Half the equipment looks like $1mil price tags (at least in the R&S part).

This is só exciting to watch. That QAM4096 was nuts! I also got caught by the "everybody has one" on the R&S generator hahahaha Definitely, it must be really interesting to work for a big design and test company in the US.

You are going to need a wider lens to fit all the instruments in the opening shot! Great to see how you channel has grown over the years. Keep up the good work, it is the most in-depth regular posting RF content I have found on KZread. Invaluable resource.

...and he's into high vacuum now, too. Cancel the fisheye lens order, I think this one calls for an entire Google Street View car.

2 THz up and down converters, 4 kelvin caps, and a 100+ output switch that looks like a cyber-cactus. God, I love RF.

looking through the window of the sweet shop!

What a great year at IMS🎉

I'm a DC guy. Anything above 100kHz is radiofrequency as far as I'm concerned. I can't understand a thing you're saying. But still, I'm watching all the video. Even if I don't understand, hearing an expert explaining all these high tech instruments is still a valuable lesson.

I'm similar... Having said that, I strongly suspect that Shahriar considers anything below 1GHz (maybe 10GHz by now) to be 'basically DC'. All of us can be 'experts' at something if we try hard enough... After > 60 years, I consider myself to be a quasi expert at breathing. (Maybe not an expert, but I haven't failed... YET!!!)

Interestingly i have seen people who work with these VNAs where the components are put into waveguide with 1 mm diameter, for whom everything below 100 GHz should be electrostatics, but who become lost when they see a directional coupler for the 20 m band.

The device on the table at 11:30 is the Nokia E-band backhaul on glass prototype that he talked about in a video last year on the Nokia Bell Labs channel.

More like microwave week in Washington AC

Awesome....cheers !

Not having to use a PM5 to do power calibration above 110 GHz with the R&S equipment is amazing news. The hours I have wasted working on power calibration...

Straight into the 'DC' microwave of course!

It would be nice if all the universities teachers s were at your level and with your willingness to share what you know 😊 …+ to have the equipment at their disposal….

Yes, please an explanation of the thermal camera system you showed. What is the physics of these even called?

Yes, speed because selfheathing in GaAs and InPh is below 100ns and scale down by the square of the dimension.

In this episode Shahriar visits an alien technology showcase.

Grate exhibition and v. Good experience

what is a phase noise modulator and analyzer ??

Aaronia booth was the coolest one to see by far, those rtsa are insane.

"everybody knows them" me never heard about this company

Witchcraft :)

this is to specialized for youtube :)

@25:09 Shahriar overwhelmed? that must be first!

2THz? That's almost infrared at that point...

@mechofdeath1504

That is infrared (300GHz to 400THz).

I would like to see a video where the actual engineers who built this stuff show us how it's done. The equipment shown is basically magic. Also I guess the price is also astronomical.

Many of these instruments have been reviewed and torn down on my channel. Including example experiments and theory of operation.

@@Thesignalpath Shahriar, I was thinking of actually talking to the engineers and designers on their daily work (like actually on their desks) while they design these amazing instruments. I would really like to see their daily work flow. These instruments are not just test gear. This is high end design and research. Also, cutting edge software. This would mean a rather long video but worth it. I would start with a day-to-day meeting that the project managers would have and then go to the details of the engineers and architects. This could be an amazing video. If anyone could do it, it would definitely be you. Thank you for all your very cool videos!

Is there anything in this video that is NOT ITAR 😂😂😂😂

Would be nice if my people weren't seen as enemies and we could visit such exhibitions.

😁 Thank you so much for the kind words. 🛰️⚡📡🧲
