This introductory video describes how complex impedance and admittance are represented on the Smith Chart, and how to convert between them. A VNA is used to illustrate the complex impedance representation on a live smith chart with variable resistive and reactive components.
Notes can be found here:

I have never used one of these because I just could not understand them. An expression comes to mind, "When you're ready to learn, a teacher appears." It took me over 60 years to get ready and it was worth the wait. I'm looking forward to digesting the rest of your well-versed series. Outstanding. AD6AE

This is the best explanation of Smith charts I have ever seen. Thanks for sharing.

@bmacdoug Год назад

Thank-you for a level of clarity that can only be achieved by someone who has a deep understanding of the topic. Two thumbs up!

@dwarslopers Год назад

Thanks to this video, I will never forget!

Dynamite presentation on SCT (Smith Charting Tricks)! Useful, terse, and crisply structured. Had even two people just like you been my colleagues at my first employer (3M Company) I would not have resigned in 1972 and gone off to medical school. But I did and the rest is history. Thanks for putting out this video. de NK7B

Clearest smith chart tutorial I have seen by at least an order of magnitude. But I can't plot that on a smith chart . .. yet.

@TheCondoInRedondo 6 лет назад

Best explanation of the Smith Chart I've ever been exposed to. Just the right amount of explanation. Not too much so that it's confusing. Not too little so that it lacks meat.

@moustaphamuhammad7013 5 лет назад

Exactly!

@phrack9998 6 лет назад

I've just been thinking I need to learn Smith Charts, and here is one from one of my favorite channels.

@bsalai 6 лет назад

I’m excited about what is coming next. How to use the Smith chart to solve complex impedance problems and design matching networks. Thanks so much.

@BASANTABHATTARAI 6 лет назад

And this is why i like this channel. I like how you are covering the electronics course bit by bit for students with “hands on”technique. I like very descriptive and precise videos of this channel.

Very nice demonstration Alan. Half a year ago I gave a lesson on smith charts and network analyzers in my company so I will share your video with my departement. Thank you.

@niteshbushan 5 лет назад

I have been learning a lot from your videos. Working as an engineer in semiconductor org sometimes we forget the theory since we know practical stuff. But your videos are a bridge between the engineering theories and practical knowledge. Thanks a lot sir :) Please keep posting more and more videos.

@w2aew 5 лет назад

Thanks! I am still doing them as I find time.

@royshashibrock3990 4 года назад

The best, clearest explanation of Smith charts I have seen. A bookmarked video for reference this will be (as Yoda would say).

@SuperFritch42 6 лет назад

Thank you for going over this! I wish I had this a year ago, but now I can point my friends to it before they get to Smith charts.

@Impedancenetwork 6 лет назад

Oh my god that is awesome. I just completed a EM waves course at school where we learned transmission line theory. It is very cool to see this on a VNA and your setup to model this.

@funkyironman69 5 лет назад

That's the clearest explanation I've seen yet, I liked the demos on the VNA.

@Loscha 6 лет назад

Thanks again, Alan. Another really well made informative video. I don't ever use anything radio based, and I think I'm glad of that after watching videos like this. I do audio (music equipment - pedals, synths), and a lot of your videos have a good use in this community. I refer people to your videos a lot. Happy new Year!

Thank you so much. This is the best explanation about the Smith chart I have ever seen.

@rfburns5601 6 лет назад

Thanks for taking the time to make the excellent videos that you do. You show theoretical principles in a practical real world light. I guess that's what I'd like to see with future Smith chart videos, is practical examples of matching problems. I'm sure you could come up with some real world examples I wouldn't dream of. Happy New Year!

@patrickohara9901 6 лет назад

Very informative. I look forward to your subsequent videos on matching networks - a real problem for many.

@Ronbob59 3 года назад

Alan... Thank you for this video. I never understood the Smith chart until now. You make it all very clear. Thanks Ron

@billmoran3812 6 лет назад

The best lesson on Smith Charts, that I've seen.! That's one subject that I've always found difficult. Impedance matching network design would be a great follow up.

@w2aew 6 лет назад

I certainly plan on that....

3 года назад

Very good practical demonstration of Smith chart !! I can " really see " what are effects of each component of complex impedance and how they are interact one with other. Thank you for sharing and construct this practical "geared elements demonstration circuit" - if it could be thereby named. :) Thanks a lot !

@RapperBC 3 года назад

As an introduction to what's going on in a Smith Chart, that is just a bit mind-blowing. How cool is *that*? Many thanks!

FANTASTIC! Best explanation I saw around, very pedagogic. Eager to see followup videos since I would like to characterize/tune Sub-GHz (800-900Mhz) antennas myself with SDR :)

@kellingc 6 лет назад

You did a wonderful job, as usual.

@NexxuSix 6 лет назад

Thank you for the explanation of Smith Charts. I’ve seen them before, but never knew how to use them, or how the worked. Your video offers a clear explanation for even a beginner like me.

You've found the other ones I've done already, right?

@MarkBaldridge 5 лет назад

Yes! Since writing that comment, I found them! :) Thank you!

Very good demo and explanation Alan. more on the Smith chart please.

@acestudioscouk-Ace-G0ACE 3 года назад

I've just bought a Nano VNA and was wondering how the Smith Chart worked so this was very useful... and being a video, I can watch it several times so that my old brain can absorb the information!

@Factory400 6 лет назад

I am so excited about this!!!! Your explanations are the BEST. Alan, if you were stranded on Gilligan's Island - they would have been saved before the second episode aired.

@w2aew 6 лет назад

I think the professor could've saved them many times, but he secretly liked being stranded on a deserted island with Maryann and Ginger.

@TheBandScanner 6 лет назад

Great video. I just received a Peak-Atlas LCR impedance meter. It does the maths for you; but seeing a graphical chart is so much more satisfaction.

@ParmMohan-us6rn 6 лет назад

Awesome! Very well explained! Great job!

@campbellmorrison8540 4 года назад

As always a brilliant explanation. Ive always wondered what these carts are all about, now I have a much better idea :)

@rodericksibelius8472 2 года назад

Great video: Simple to understand, I had to learn all that complicated mathematics and explanations in Electrical Engineering books written in a very hard engineering jarjon when I was studying, this VIDEO explains it so easy to understand. Smith Chart makes it easy to use by Engineering Microwave Technicians or a Hobbyist.

@wk2w 6 лет назад

Can't thank you enough, Alan. This video is a perfect complement to all the other info out there. Seeing the immediate effects on the VNA is invaluable. Appreciate your efforts in putting together the L/C network. A very nice introduction. Would be interested to see an "L" or pi network solution to a complex load like an antenna on the VNA, if you would be interested in doing something like that. WK2W

@w2aew 6 лет назад

Yes, I certainly plan on showing how to design a matching network using the Smith chart, as well as a few other things... Stay tuned!

@todkapuz 6 лет назад

Happy New year.. thanks ... while i knew how the chart works, sure is nice to actually "see" it in action persay.

@mickeyaslam5272 6 лет назад

Yet another great video. Thanks' for sharing knowledge and happey new year and best wishes.

@7head7metal7 6 лет назад

I took RF and wireless communication lectures during my EE studies in university, but nowadays we don‘t learn this anymore. I still always wanted to learn this properly, so thank you for this video! :)

@7head7metal7 6 лет назад

- Eth that's interesting! I'm in Germany, here I didn't stumble over Smith Charts anywhere in my daily work, but their use in classic analog circuitry is still there, at least for manually solving. But were you ever required to actually use it in your daily work after the interviews?
