Every University Teacher must watch this before teaching to students. Perfect, clear and neat way to explain. I request your team to continue posting such videos. Thank you so much.
My points exactly. As someone recently called to teach simplified communications in radio, these videos are an excellent source of refreshment of essential principles. I love the concise and pitch (for my level of interest anyway) of these videos and will take a leaf from the presentation style of these presentations.
I’m so impressed by how effective your short videos on VSWR and S Parameters are. I’m a lecturer who hasn’t worked in the field for many years but does occasionally dabble as a hobbyist. Recently I have been called upon to teach fundamental radio communications and it’s very refreshing to see these videos. Thank you.
That was really well done. It was the perfect presentation style (at least for me). And there was little to no subtle marketing of your company's brand; you simply presented the base concepts along with some historical background of who the Smith in "Smith Chart" was. I understand this so much better now. Thank you.
I recently purchased a NanoVNA to tune my HF amateur radio antennas minimising the needing for a matching transformer. However, I was sticking to the VSWR display because the Smith chart looked complex. Thanks to this video I have found out so much more from reading Smith chart graphing now that I understand them! Thanks for making this understandable and clear.
Excellent. Just excellent... being a maths "dumbo" I've always struggled with the Smith Chart. Being a licensed radio amateur a proper understanding of the chart, it's functions, AND HOW THEY CAN BENEFIT ME by properly understanding them escaped me year on year,. NO MORE. Paul, Thank You ! this presentation should be part of every single radio amateurs course ! Am very very grateful to you for this more than excellent video. Your companies instruments for us radio amateurs are the stuff dreams are made off. Sadly... lottery tickets to win them are far and few between... but,... we live in hope! Thank you again Paul. Albert
This is the best Smith Chart refresher/lesson i've had. It makes me think why it has to be so complicated before. The technology ( video/graphical presentation) helped . Thanks. The training materials on this site , are all so Zen like.
Thank you very much! I have started to read about Smith charts many times but always given up before getting to grips with it. Your professional presentation lifts the mystic vale and reveals the elegant simplicity of the chart. Thank you. Kind Regards . . . Andy. gw0jxm
I have nearly no idea how to apply this or when I'll use it but the graph usage was explained clearly and consisely. I have no background in electrical engineering but I'll come back to this at some point
Great simple easy effective way to communicate how to use smith charts for understanding impedance. Thank you. This was very helpful to clear up and confirm a couple things I had been working through previously.
The VNA @ the end of this video is a righteous piece of work, would really enjoy seeing a tutorial on that piece of gear in use. Those handles on the front are so you can hang on to it while it rests on the night stand next to the bed.
Check out the Test and Measurement Fundamentals playlist at the top of the R&S TH-cam channel: I've done a number of VNA related videos already and more are on the way! And as someone who worked as field apps engineer in T&M for > 20 years, I have a lot of experience with those handles :)
Very good. Thanks. only people who understands the subject clearly can explain in simple terms - ofcourse one should have passion to explain. Only few people explain to be understood while many others explain to make it sound complex.
Even though I've been working in test and measurement for over 25 years, I still learn something new myself every time I start making a new video. :) Thanks!
Thank you, I just found your TH-cam Channel, but I have your Electronic Warfare pamphlet, and at least one Radio Spectrum chart. I operate a ship, and the radios, internet, satcomms, secure comms, and I'm looking to detect signals that might prove hostile. and hoping to maintain comms with the office, home, and on the ship. Plenty of radio challenges. I'm tackling them as they present themselves. Thanks for the learning materials!
wow. This is one of the best, most effective and efficient educational presentation of practical - u s e f u l information I have ever seen. In 294 seconds. Useful because my Extra ticket expired during a crazy time of life, and I will be retaking it, building a station, and doing SOTA POTA outings. Practical, because 4.2" TFT display, 50Khz-1Ghz VNA's can these days be had for $90-$100 delivered. My thanks to Rohde Schwartz and to the creator(s) of this video. Educational excellence beyond compare.
Great presentation. In the example at 8:47, when you normalize the complex impedance, why does only the sign on the resistive component change? If I factor out -1, shouldn't we get -100 + j75 = -(100-j75)? Then -Z/50 = 2 -j1.5?
Yes, Z0 is the characteristic impedance and ZL is the load impedance. In many RF systems, Z0 is 50 ohms and our goal is often to find a way to make the (variable, frequency-dependent) load impedance ZL "match" the characteristic or source impedance Z0 at a given frequency or over a given range of frequencies.

My professor understood the assignment 😂
Wow you're the best. I spent 2 hours in class and didn't get a damn thing but this 10 minute and I feel like an expert. Thanks a lot.
Thanks!
God bless you mate, I have an exam today and I couldn't understand a single word from my brain-dead teacher. Thank you!
Are you an EE now?
@@Countolaf03 no, not anymore
What happened?@@PedramNG
@@PedramNGnooooooo what happened
Has been 15 years I'm looking at antenna theory and never understood a Smith chart. In 10 minutes, I got it
It's been 50 years since I first saw the Smith Chart, never got it; now I understand a lot of things in ten minutes. Thanks. K4QET

A perfect way of explaining things. This guy should get an all time best-teacher award.
Thanks!
This is the best explanation I have ever seen Understanding the Smith Chart. Well done!
Thanks - really appreciate it!
Back in school, the Smith chart was clear as mud. After watching this video it is a lot clearer. Good job.
Glad it helped - thanks!
Kudos Rhode Schwarz - these illustrations are invaluable. Thank you so much!
Thank you!
Saved tons of hours studying and listening to my course instructor!
I have nearly no idea how to apply this or when I'll use it but the graph usage was explained clearly and consisely. I have no background in electrical engineering but I'll come back to this at some point
Glad it was helpful - thanks for the feedback!
Absolutely phenomenal!! Sir, your videos have helped me a tremendous amount in my course!!
Thank you Rohde Schwarz!
Great explanation! Now I understand the display on the VNA better.
Thank you. That was the best summary on the Smith chart I have seen.
Thanks!

Perfect
I understood without even handling a pen to write down
Nicely done
Thanks!
Short crisp and very well explained!!
Thank you!
solid 10mins cover my professor's 30mins lecture on smith chart
thanks
This is a great primer on understanding Smith charts. Very detailed explanation!
Amazing way to discuss importance of smith chart along with illustrations.
Very good. Thanks. only people who understands the subject clearly can explain in simple terms - ofcourse one should have passion to explain. Only few people explain to be understood while many others explain to make it sound complex.

The best and most precise video!!
Appreciate the content and the length of the video :D
Helped a lot! Thank u so much!
U explained in a very simple manner ☺️ this giant type looking smith chart..thanks 🙏
very helpful series of videos paul
Clear and to the point. Thank you
Well done! I actually got that lot, You have a gift!
Clear and understanding.... Good presentation
Very good explanation 🌹.
Thank you
Thanks!
10 out of 10 I now remember what I learned 40+ years ago, god it was hard to do with a pencil
saved my day, great quick explanation
Well done. I think for many viewers, showing a 2:1 VSWR circle would help.
Actually, I'm planning a number of other Smith Chart related videos, including one on constant VSWR circles :) Thanks for the suggestion!
Very well explained - well done!
Perfect and clear! Great thanks! It's very helpful to the person who never studied the electronics theory.
Thank you!
Great effort.. Thank you, Keep it up

Thanks for the learning materials!
Well done, a wonderful explanation, it was very easy to follow you step by step.
Beautifully explained....Thanks a ton....
Very much appreciated :)
Very efficent teaching! Thank you!
Thanks - as an engineer, efficiency is very important to me :)
Perfect explanation. Thank you, sir.
Thanks!
The greatest use of the smith chart is two wizards trying to simultaneously counterspell each other...
Thank You
Simply amazing, Thanks
The Tōsaku Mizuhashi Chart was published in 1937 two years before this Philip Smith Chart!!!
Many doesn't realize that testing is as challenging as designing something if not more challenging
I feel exactly the same way :)
Awesome Explanation.
Absolutely helped me with making a PB&J sandwich
thanks, thanks, thanks... great explaination
Well done best explanation simple and clear
Thank you!
Thank you!! Very good presentation!
This just saved my bacon! Thank you
Glad it was helpful!
It is very helpful.
thanks a lot
Always a great quick refresher course when you do not use this tool on a daily basis.
Thanks for the feedback!
Great very easy to understand now thankyou!
Amazing
This is million times easier than the Wikipedia page
fabulous, speechless
very nice explanation
Yeah you should definitely watch this
Thank you so much !
Nice job!
Really awesome. Helped a lot. Thanks

Top class !!👏👏👏
Smith Chart made simple.
GREATEXPLAINATION
Great video! Thanks.
Thank you very much
You are amazing...thank you..🙏
Thank you bro god bless you!🦾
Thanks!
Is that a vintage Rohde Schwarz VNA shown an the end? If so, what year would that be (approximately)? Just curious. BTW, freaking great video!
Thanks! That's the Z-g-Diagraph, the world's first network analyzer, which was developed by R&S in the 1950s.
Baller video, pat yourself on the back you beautiful bastard!
Thank ever
Great presentation. In the example at 8:47, when you normalize the complex impedance, why does only the sign on the resistive component change? If I factor out -1, shouldn't we get -100 + j75 = -(100-j75)? Then -Z/50 = 2 -j1.5?
What about wavelength? For example, If i'm trying to solve for a cable of certain length...
There are LOTS of things you can do with the Smith chart. I'm planning future videos on topics like the one you mentioned.
This video means my professor spent 30 minutes explaining basically nothing
ne of the reasons I made this video is that everyone assumes that people "know the basics" but no one ever seems to actually explain the basics. :)
👍
Dzięki !
Is Z0 the same thing as the characteristic impedance? Just trying to make sense of it in terms of my class
Yes, Z0 is the characteristic impedance and ZL is the load impedance. In many RF systems, Z0 is 50 ohms and our goal is often to find a way to make the (variable, frequency-dependent) load impedance ZL "match" the characteristic or source impedance Z0 at a given frequency or over a given range of frequencies.
That’s crazy but what are we going to need this for in life ?
Well, if you are an RF engineer, you might use it fairly often. In any other field, maybe not so much :)
