21:11 - SV1AFN GPS Disciplined Oscillator
This GPS disciplined oscillator not only provides frequency synchronization to the GPS clock, it also provides programmable outputs on two independent channels using a Silicon Labs synthesizer IC. The complete module acts as standalone unit which only requires power and GPS antenna connection. The full schematic and block diagram of the synthesizer chipset is presented along with measured output waveform, frequency an phase noise at 1GHz. You can purchase your own GPS DO here:

33:28 - Sain Smart USB-C TS80 Portable Soldering Iron
This soldering iron which supports QC 3.0 is the followup of the very popular TS100 soldering iron. The unit can operate with up to 18W of power from 9V. However, it does not support PD on USB-C. By using the AVHzY USB tester the power bank can be configured to provide any desired output voltage and deliver up to 28W into the TS80 soldering iron. Using this method, the TS80 soldering iron can easily solder large components on a wide ground plane. The TS80 soldering iron can be purchased here:

Hmm - I've got a 23GHz scope here - we should be able to see the raw performance of that pulse generator on that. Let me know if you want to give it a try.
Make more videos, Alan!!! ;) -73
w2aew, can you tell us the name of your 23GHz scope?
Thanks Alan! I going to measure it with our 63GHz, 160GS/s scope as well! There is also a 90GHz sub-sampling one I can use. What 23GHz scope do you have? Whats the sampling rate?
@@Thesignalpath It's a Tek DPO72304SX, 100GS/s sample rate.
@@nickstanley5064 It's a Tek DPO72304SX, 100GS/s sample rate.
Sorry for the faulty biscuit tin, Shahriar!
I am sending you a few field replacement kits that should take of that problem.
Cheers
Leo Bodnar [Electronics]
Why did you guys go with the female connector? Just out of curiosity.
They are rare and expensive, and don't exist in compression mounting format I am using for compact layout. If you use good quality adapter the difference would only be a few ps.
Generosity = Shahriar Shahramian. Thank you for sharing: 1) All the knowledge with clear explanations 2) the "Hands-On" practical demonstrations & experiments 3) finding and sharing neat stuff from around the world (i.e. UK & Greece) and 4) One Simple Wish. Your supporting them is great, but exposing this great charity to me is even greater. Thank you again.
I live in Ecuador and currently I have a Sencore SC61 I bought second hand before moving. I would really like a digital oscilloscope especially a high end like Keysight. Your videos are very complicated to follow at times and challenging to follow. They are more like a seminar. Before I watch I usually get a cup of coffee. In order to concentrate and try to understand the material you are presenting. I have learned so much. Thank you for your consideration and keep the videos coming... Also, I love watching Alan W2ea and Dave EEVBLOG videos. Thanks again
Those MBlox GPS modules are great. Using one of those from ebay for like $7 (!) I was able to calibrate my ovenized 53131A counter to LSB in no time (well, a few hours). Simply load an hour (or two) of PPS data into a spreadsheet, clean it up, take the average and there is your error to adjust. Rinse repeat. Now my counter serves as a 10MHz reference (clock output is powered even when the rest of the unit is off)
Starting a consulting business for electronics. A nice scope would be a great start. I have loved all of your videos over the years. Thanks for all of your efforts. Time to support on Patreon. Cheers.
Great in-depth reviews as always.
I am doing my master in computer engineering and the keysight would be a great upgrade for current and upcoming projects.
Thank you for all the educational content. I would like to use the scope to gain some hands on electronics experience doing some projects. I feel EE university education is somewhat detached from actual hardware design and a scope is probably the most important tool to dig deeper into electronics in general. Looking forward to it.
It's super awesome when someone knowledgeable takes the time to share some some real world experience with us. I'd love to poke around with that scope to try and reverse engineer my mini split thermostat thats garbage.
Hey Shahriyar. I love watching your videos. You know I started watching your videos without knowing your name and I was enjoying the contents of them so much that I got curious where this guy is from as I could hear the accent. I was searching and then I saw your name, I was so surprised you are from Iran and your name is the poet of our city Tabriz. I just write to say we are proud of you. I am a repair man in tabriz fixing inverter Welding machines and I learn so much from your repair videos. I wanna say thank you and want you to know that we appreciate your contributes.
Thank you. I am glad that you enjoy the videos.
Shahriar, I don't comment often but the lure of a working scope was an opportunity that I couldn't miss right now.
Thank you for all that you do and the videos that you make, I really get a lot out of them. I am self taught with no formal EE education [although I am considering working toward a degree part time] and currently work for a small company designing passive RF attenuators, filters, and equalizers. What I do is not complicated by any means, but there have been times that concepts I picked up from your [and others] videos has helped me decrease my RL by that extra.5dB or so.
Yes, I would like that o'scope and would get much use out of it.
Best regards,
Trent Spencer - KM4YTU
Would love the oscilloscope; I'm a college student who can't quite justify the ~$1000 for a scope, but could put it to great use! Would like to design a custom BLDC controller, some reverse engineering of cheap calipers, and finally track down some issues with projects I've already built.
As always, concise and detailed looks at your mailbag items. Thank you for the effort you put into these videos. However, please specify temperatures in degrees C as well as Fahrenheit, next time?
That USB PD trick is awesome! Thanks for sharing! Would love to participate for the DSO as well, would use it to develop my EtherCAT slave project further (a demo video is on my channel).
EE Student in my graduating year, would love that scope to get going on some homebrew projects (some IoT, home automation, and audio projects are what I have lined up) to build on what I've learned in the classroom and develop a bit of a portfolio. Love the content! Keep it up!
Very interesting, I was having a look at those fast rising edge pulse generators just yesterday. I'm curious if they produce stable outputs over long periods for broadband analysis experiments. I could give that scope a good home.
Interesting video once again! The oscilloscope would be very convenient for my own electronics projects at home! At the moment I'm using a cheap PC oscilloscope, which does the trick for simple measurements, but is insufficient for more advanced projects that I want to experiment with. Thank you for the opportunity!
About the holdover mode of the GPSDO, I think the frequency drift will look exactly the same no matter how long you leave the unit on because the drift we see represent the short term stability. I understand that if the unit is left on for a long time, its firmware can learn to improve the long term stability. However, I'm a novice and I don't have any experience with TCXO or GPSDO. Perhaps this device need a minimum amount of time (30 minutes? 1 hour?) to achieve better short term stability (Better than the rate of frequency drift in this video.)
Hi, I need a DSO to debug a project I have. It's running at 48MHz from a Microchip PIC to output ICSP data and I'm actually having trouble since I changed to a PIC16F1455 from a PIC18F2450. I have an oscilloscope, but don't have the storage option and capturing the long data output is not possible. The DSOX1102G would help me compare the old data wave that works correctly with the new data wave. And I could store and compare these in anlog to compare the data and the switching for the rise a fall times.
Greetings from Aalen in Germany! I am studying Optoelectronics and its nice to have Videos like this. Its always good to learn something new next to my studies!
Leo Bodnar is awesome! Have you heard about his high altitude balloons?
This was one of my favorite videos of your recent few. I am going to pick up one of those usb irons; it won’t match my metcal station but it will be great for on the go work- much better than dealing with my butane iron!
Would love to have an extra chance towards the scope giveaway... thanks as always for the great videos.
As EE student and hobby electonics person, that scope would help me test my deaifns on another level! Thanks for sharing.
I’ve just discovered your channel, It’s a little bit complicated for me but the subject seem’s realy interestting. Keep in touch
Would love a chance at a scope and function gen in one package. I’m a huge fan, I really enjoy what you have to teach.
I would love to have the oscilloscope, I was a tech in my youth, but worked in sales for 35 years. I'm retired and started back in electronics fixing friends equipment and starting to build and mod all sorts of things. The scope would help immensely, in fault finding and testing what I build. I only discovered your channel today, 15 Nov, really liked the soldering iron you reviewed too. I'm looking forward to watching more of your videos and checking out how patreon works.
Your repair and teardown videos have really helped while trying to repair stuff myself :)
Would love to have a modern scope on my bench both for repairing stuff but also debugging the faults in my own circuits
I’m really enjoying your videos. Although an oscilloscope will be a good motivation to get more hands-on!
Hi! I've started studying EE this year but been oogly-eying a good DSO for years, never being able to justify the cost. Being able to work with this scope would be amazing!
Great content, as always. The Keysight giveaway would be a huge upgrade from the DSO138 kit I built a while back.
Nice timing I was just looking at getting one of those LeoBodnar pulse generators, I think thats sold me on it.
i have watched ll your videos and enjoy the tear downs and repairs and the way you take the myths out of the equipment and as most i have never been able to aford any kind of scope and oly ever looked at the 10mhz ones but never been able to use one and would love one to use and lean and make electronics and repairs so much easier.
I really was skeptical of those USB soldering irons, but I can say you changed my mind in that 1 min of demoing it
Great reviews, with GPS oscillator if it uses 50Mhz crystal does it have another LO or is it on chip to produce output frequencies upto 1GHz in addition to using GPS clock, I am assuming its uses a PLL?
Thanks for another great video. That scope would be a nice addition to my lab, so I would like to enter. It was nice to see the performance of your scope collection :)
Packed with information as always! That DSO would sure come in handy, I don't have my TEK 464 anymore so I'm limited to work with stuff I'm really confident with...
Am building up my lab for repairs and want to start working on some audio dsp projects, the 1102G would make a great fit! Thanks for he awesome videos!
Would love the scope! I learn a lot from your videos. I'm always happy to see a new one in my subscriber feed.
Hi Shahriar. I have been following your channel for at least a year. You fill a unique niche for people like me. I have a BSEE, but I beliee that I've learned a lot more from your videos than I ever learned in school. I hope to win the scope , as I don't currently have one, or een a working DMM at the moment. Watching your videos make me ache to build a circuit or debug a broken instrument. Best regards to all of you.
Thank you for this video! Is there a way to estimate rise fall time of this pulse generator on a spectrum analyzer? Fast rise and fall must give a very broadband set of harmonics...
Try connecting the pulse generator to a spectrum analyzer and see how close the harmonics are to an ideal square wave?
I'm very interested in the scope! I would be interested to see you teardown some of the other gpsdo on the market. That or a rubidium clock.
Thanks for this review, Shariar, informative as always. I'm wondering why nowhere in your rise time measurements with Leo Bodnar's pulser you seem to be taking the pulser's own risetime into account, except where the 'scope's risetime almost equals the pulser's. Have I missed it?
This is significant especially with regard to the 1 GHz LeCroy HDO6104-MS, which achieves its rated BW at 990 MHz as you state and the R&S 2064, which only reaches its nominal BW if 4.5 is used in the risetime/BW conversion, not with 4.25.
The others obviously reach their stated BW but how fast is that 13 GHz HP, taking the pulser's risetime into account?
i have enjoyed and learned a lot from your videos, thank you. inspiration from you and a few other electronics repair, review and educational channels has sparked my desire to set up a small electronics lab in my home. i studied electronics in college many years ago and that provided a foundation for my career in telecommunications. i am now retired and wanting to establish a means to raise money for some nonprofit organizations in my area that promote the arts and also help disadvantage women. i believe i can do this by using my lab for repairs. i have a modest fixed retirement income and your oscilloscope giveaway would be a big help in achieving my goal. Please keep your very interesting videos coming.
I like this new video category. But the long teardowns/repairs are also very nice.
I have a small home lab. I could never get a scope, so it would really be helpful, especially since recently I been getting more into DC-DC converters, it would be nice to be able to see the actual output and control signals on a scope.
Great channel! Interested in the DSO if it is still going on - I'm currently using a $20 diy scope, the upgrade would be nice.
Hi Shahriar! Can one of this pulsers be used to measure probe + frontend bandwidth ? Or the sole idea of measuring the sma / box output with a probe is really useless ? Then, how to test a probe bandwidth ?
As an EE student I'd find very good use for the scope for my hobby projects. I'm currently using one of these terrible USB oscillosopes with which I often spend more time getting the thing to trigger properly than to set up the circuit I want to probe.
I've got the saleae signal analyzer but recently I have seen the need for an oscilloscope for other high voltage projects would be very good appreciated, BTW great videos, got to know you from the amp hour podcast a while ago
It is really nice how these days people give away all kinds of gear on youtube etc. but unfortunately as a hobbyist I could mostly often even afford those things, so I wonder if it would maybe make sense to give away multiple but lower priced items. Some of the kind of "that would extend my capabilities, but its a bit pricey to buy it just for that". Like second multimeter (or third or so), many hobbyists try to get away with the bare minimum, but being able to cross check with another instrument or measure current and voltage at the same time. Or an edge generator ;) Or maybe some cool project building blocks, like I for myself am having an eye on some fast photomultiplier tubes but again, just to play with them and maybe come up with something usable but possibly break them, it might not be worth it, there are things much higher on my "to-buy" list.
Unless of course you want to limit the give away things to your own country only, then that extra cost point becomes moot.
Thanks for the video, always cool to see these high end scopes pushed to their limits! I already have a Rigol DS1054Z here in the lab, so someone else can have the (very nice) scope!
No need scope, just to say the risetime comparison was very nice. Perhaps part 2 with fast samling scopes? ;)
I would love to enter for that scope. Thanks for the great videos as always. Guess I should mention I'd be using it to continue teaching myself electronics step by step. I have an old 70s scope that just doesn't do the trick anymore and I think with I new one I'll be able to take it to the next level.
right
Its fantastic your gift to onesimplewish. I've been a hobbyist all my life (63 yrs old) and my old analog scope died years ago and I couldn't justify the cost of a replacement. I love the fact that so many share their knowledge, I wish you tube was around 40 years ago. By the way I would love a new scope.
At 25:00 when you look at the schematic for the GPS module, you say that the jitter and phase noise is bad, but the frequency accuracy is good. I thought that these three parameters is kind of correlated. Isn't jitter the same as frequency accuracy?
oh and as an EE student, gimme da scope!
You're videos are superbly refined and polished. Excellent as always. Thanks a lot.
NO SCOPE for me, just another thumbs up for the great work you do . . . , : )
Hi - I don’t think you can prononce SV1AFN - it’s a Greek amateur radio callsign! Please count me in for the scope draw. I’m just retired and getting back into hardware after a forty year diversion into software!
The pulse generator is a piece of art - thank you for describing how it works.
And I never thought that 20W solder iron can handle big polygons with such an ease.
Count me in for the draw.
Another great review! Who ate the cookies Shahriar? 😉 Thank's for the chance to win the scope.
I‘m still using my first analog scope I got from a sale 10 years ago. It‘s pretty useful after a view changes I did to it. However - A nice DSO would be a nice addition :)
Great job. Here in my country, Brazil, It is not so easy to have one scope like this...
In my lab, most of the high frequency test equipment has male connectors, for example the 1.85 NMD on the VNAs. I think the male connectors are more robust than the female connectors.
Really interesting to see the microstrip design techniques in those modules.
A scope would really help my modest test bench, so fingers crossed!
Hi Shahriar, very informative video, as always. The USB soldering iron is very impressive, if this were a TV ad I would not have believed it. As far as the giveaway; I would love to have a Keysight Scope on my bench. That is a very nice scope and this is a very generous offer. I wish everyone good luck. Thank you for all you do and for being such a great teacher.
Now I have to consider whether I can buy that soldering iron.....oh, just looked at the price and I can't :-( . As a retired EE hobbyist I would love to enter the draw for that oscilloscope... which I definitely can't afford to buy.
Clever trick to dump more power into that iron. I wonder if that has any bad effects, though.
Hello Sir, Mindblowing gadgets seen today, I really have to show to the RSGB radio club !, wow so impressive selection glad you had time to show them off, all very impressive,
I've been trying to find a GPSDO with a 1pps time output that has a hold-over mode that is affordable. A lot of equipment such as SDRs expect you to provide them with a 1pps time signal from a GPS receiver and since you can't always receive a GPS signal, a frequency standard with a 1pps output is the only other option. But rubidiums are pretty expensive and bulky so I would like to find a small portable GPSDO with a 1pps time output I could take it outside, have it lock and discipline itself to the GPS time and then take inside where I could use its oscillator in hold-over mode to feed my experimental SDRs with 1pps time signal while still close enough to real GPS time. Anyone have any tips where to find something like that?
I'm an EE student, but the lack of a scope is really hindering my development of an intuition of some of the more esoteric concepts I've come across. A good scope (or even a "bad" one) would be a lifesaver.
I really like your channel and I think its great that you are bringing attention to the One Simple Wish Charity. Thanks!
There are a lot of talented young engineers who will need this most. Give them a leg up with a great scope.
Great video again! As an electrical engineering student I would really love to get this scope!
I’d love the scope and especially the function generator capability. I’m a paraplegic and I’m working on a project to integrate various health sensors into a stationary hand-cycle to allow safe exercise.
People with spinal cord injuries like mine have more than just mobility limitations. Often we lose the ability to regulate body temperature, blood pressure and heart rates which can get dangerously high without warning. So cardio exercise can be a challenge if vitals are not continuously monitored. I need equipment to capture the output of various health vital monitoring devices and regenerate their protocols from a hand cycle with integrated/connected sensors that can monitor the user and communicate their body’s condition to local or remote displays. Don’t want to get into all the details here. But please consider this project. Thanks!
The scope in our lab is boot looping and way out of warranty. Now we're measuring with an old CRO. We need a new one to get back to work
Would absolutely love to have a chance at that scope. Thanks for another great video. Enjoyed the the epaper video, nice change of pace from the great dark arts tear downs.
Can anyone give me advice please? I am curious to know whether I can use this Fast Pulse Generator to measure PCB trace impedance or not? It seams to me that I can build a TDR (time domain reflectometer) combining this Fast Pulse Generator with my oscilloscope.
great videro. thanks for the info on the TS-80 - great idea with the power tester/PD thing.
FYI, SV1AFN is a ham radio callsign The SV prefix is from Greece.
Nice review though.
Also, I’d really like thar scope.
Excellent video, as always I don't work with HF but enjoy learning something new.
Hi Shahriar! This coming year I'm going to be reading graduate level EE courses in wireless systems and signal processing. My next project is going to be a LNA built with discrete components. Life would be great with a proper 'scope :-)
Lovely to hear about the one simple wish donation. Good luck on the giveaway draw everyone.
That scope is sweet! We have them in my lab in uni. I would really love to have one, it's been some time from when I started collecting money to buy a rigol 1054z but with books and tuition for uni, I really cannot even afford that 400€ scope unfortunately
I would love the get the scope, really handy for many of my hobby projects :) By the way the AVHzY USB tester seems especially convenient.
I could definitely make use of a modern DSO. My newest oscilloscope is 30+ years old and my newest DSO is even older.
Would love the scope as I move into retirement and will be able to undertake all the experiments I have on my list but have not had time to undertake. Thanks Dave.
Would be great to have that scope - I’m hoping to have enough $$ to buy one next year if I don’t win here though
The value these awesome efforts you perform provide people with knowledge not easily available. I just became a Patreon supporter
Thanks for the giveaway and your interesting, informative videos! I am a retired home hobbyist with limited means. I could use the DSO for my repairs to my electronic equipment and further learning curve. Thanks again!!!
Nice to see a fellow Greek amateur radio operator from the old country make good! BTW, it's not a pronounceable "name" rather his Greek ham call sign characters/number "S V 1 A F N". Thanks for sharing Shahriar.
Thanks for the video and giveaway program.I wish to get this Scope with FG, which is really can't affordable as of now.
You can buy a soldering station controller from China (Aliexpress etc.) for about $30 and Jose (ptdreamer) wrote third party software for it that makes it work with the JBC irons. All you need is a battery with 18V or more (I use a Makita tool battery) and you have a mobile JBC soldering station. I have documented my version on EEV Blog.
That USB meter gadget seems nice, I was looking for a PD load.
love the soldering iron, but the DSO would the most useful sine I am looking at getting one.
Love your videos, keep up the great work!
That scope looks really nice, i've currently got a logic analyzer for debugging electronics.
That is some oscilloscope collection :) I am in for the baby Keysight, my Owon needs replacement.
Always look forward to your videos. Keep up the good work. (I could put a new scope to good use.)
I would love to have that scope. :-)
I am more and more experimenting with digital stuff and this would be really useful to learn new things. (I have a Tek T912 scope it's not the best for fast changing signals.) Thank you for those amazing videos, you learned me a lot of things. :-)
Wow that soldering iron is pretty powerful. Wonder if there ones with PD built in.
BTW i'd like to participate.
I'm a german student and starting to create my own rf circuits. Currently i'm working on a low-cost radar system, but without a scope its more or less not possible to debug the circuit at home. So it would be great to get one.
