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.
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.
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.
You're videos are superbly refined and polished. Excellent as always. Thanks a lot.
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)
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
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!
The value these awesome efforts you perform provide people with knowledge not easily available. I just became a Patreon supporter
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.
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
Fantastic quick reviews. I like the format
Would love the scope! I learn a lot from your videos. I'm always happy to see a new one in my subscriber feed.
As EE student and hobby electonics person, that scope would help me test my deaifns on another level! Thanks for sharing.
I like this new video category. But the long teardowns/repairs are also very nice.
NO SCOPE for me, just another thumbs up for the great work you do . . . , : )
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 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
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 :)
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...
Nice timing I was just looking at getting one of those LeoBodnar pulse generators, I think thats sold me on it.
These videos have become some of my faves here on YT!
Nice video as always and thanks for the featuring! TS- 80 is really handy for anyone to use.
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.
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!
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.
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 content, as always. The Keysight giveaway would be a huge upgrade from the DSO138 kit I built a while back.
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.
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).
I would love that scope. Thank you for sharing your knowledge and experience!
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.
I really like your channel and I think its great that you are bringing attention to the One Simple Wish Charity. Thanks!
Love your videos, keep up the great work!
That scope looks really nice, i've currently got a logic analyzer for debugging electronics.
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.
Another great review! Who ate the cookies Shahriar? 😉 Thank's for the chance to win the scope.
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!
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.
I really was skeptical of those USB soldering irons, but I can say you changed my mind in that 1 min of demoing it
I would love the scope! Thanks for the education you give us and the opportunity
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...
great videro. thanks for the info on the TS-80 - great idea with the power tester/PD thing.
Lovely to hear about the one simple wish donation. Good luck on the giveaway draw everyone.
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!
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.
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.
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
Thanks for the heads up on Bodnar. Great way (with the scope) for economical TDR! Also, thanks for the channel.
In for the giveaway. Thanks for the opportunity and the educational videos!
There are a lot of talented young engineers who will need this most. Give them a leg up with a great scope.
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.
Excellent video, as always I don't work with HF but enjoy learning something new.
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?
I would like that scope. I like your repair videos, there's always some more to learn.
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.
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.
Great video! Thank you for the chance to win the scope.
I’m really enjoying your videos. Although an oscilloscope will be a good motivation to get more hands-on!
Thanks for sharing your knowledge on UA-cam, Its great to be able to get a glimpse into the high performance electronics world. A scope would be a great addition to my lab and a resource to continue learning electronics!
Great video again! As an electrical engineering student I would really love to get this scope!
I was lucky enough to win the Keysight "Test to Impress" scope contest, so good luck to everyone else. The Leo Bodnar pulse gen is a fun device - I am building a test fixture to use it as a TDR source and make impedance measurements on my old 20Ghz sampling scope.
Excellent review. Really cool to see Leo's product connected to so many instruments!
Keysight really screwed up how they ran "Test to Impress" in Australia, was impossible for me to even enter.
After three straight years of impossible to enter contests, and lame promises of doing it properly next year, I no longer trust them as a company.
Kinda sad when marketing achieves the opposite of what it intended.
This would be fantastic. Thank you for everything.
Excellent work! An oscilloscope would be really useful for my projects.
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 ?
I sure could use that scope in my lab. Great video as always.
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?
Another great video from the best youtube channel about electronics. Would love to have that scope! :)
We appreciate all your knowledge you share with us! A scope that actually works would be great :)
Always look forward to your videos. Keep up the good work. (I could put a new scope to good use.)
I’ve just discovered your channel, It’s a little bit complicated for me but the subject seem’s realy interestting. Keep in touch
What is with connecting the pulse gen ac coupled to an spectrum analyser to look at it's harmonic content?
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.
Excellent video. As always. I would love to have that scope here in my home lab.
Thanks again for you channel , now to put more gear on my list of things to add to my bench ;)
Very cool of you to have a drawing! Here's hoping!
Would love the scope. I start engineering next year. Thank you for the great content.
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?
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.
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!!!
Really interesting to see the microstrip design techniques in those modules.
A scope would really help my modest test bench, so fingers crossed!
Thank you for the giveaway, As a electrical and computer engineering student, having a oscilloscope could be very handy.
Excellent video, as always. Thank you for sharing...
I'm just getting into magical world of RF voodoo and your videos are really helpful! :) A real scope like the one you're giving away would be just perfect for someone who's making first serious steps in RF field... just like me ;)
Anyway.. Thank you for all your videos and your hard work!
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,
Man I'm thinking I want that iron now. Great video!
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?
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.
Thank you for your educational videos and for the giveaway!
I would love to have such scope. I appreciate the great videos, I learn so much from them!
Thanks for the quality vids!
I like to take the chance to get an scope.
Great vids, thanks for all the knowledge
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.
I would love to have an opportunity to win that scope. Thanks Shahriar!
That is some oscilloscope collection :) I am in for the baby Keysight, my Owon needs replacement.
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.
Great videos. I'd love to have a scope for some audio circuits I've been trying to wrap my head around.
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.
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!
I would love that keysight scope! Count me in.
