I was so excited when I saw this in my recommendations, I’m really curious to know more about the ThunderScope/ngscopeclient mix. When I heard the Mario music you used in the demo I knew we were soulmates 😜. Thank you for the video!
Great demo, when thunderscope will be available?
Should be launching on Crowdsupply sometime in September! Sign up there to get an email on launch day
Its getting better every week I see. This is an awesome tool.
whats the bandwidth limit ?
500 MHz Analog Bandwidth
This is awesome!

Liked and subscribed as soon as you mentioned Meg-Ohm mode and when you said "imaginary impeadiances are quite real" , I knew that you KNOW! (Retired Microwave & Radar Eng.)
Nice details 😊
I find this a very interesting series... I'd be curious know much (if any) part temperatures might affect impact your results...with RF shielding, a power hungry FPGA and a enclosed dark metal case I'm assuming things could get a bit toasty...
It's key to let the temps stabilize before running any calibration, the unit will keep itself at 60C or so (but consistently so) at room temp after about 10 minutes. Since we can then assume constant temp, calibration will remove whatever dc offsets arise. The ac frequency response won't really change, but noise will get worse with temp, but that's just a natural fact, can't avoid it.
This is an amazing series! Can't believe it only has only 400 views, so much knowledge in these videos
i'm working on a 100msps oscilloscope for months now . the attenuation circuit really been a pain. brought out every demon i've been avoiding . you're video came to help just at the right time . but i have a lot to do to get this project done .
Now I know what an oscilloscope is doing when it is callibrating. There are a lot of modes to calibrate.
Cool project. Doesn't having only one attenuation effect the noise floor in a negative way in certain ranges?
Exactly right, noise will be worse at the lowest input voltage that requires the attenuator. As with everything, this is a tradeoff. In this case it is with cost and complexity. I tuned the attenuator value so that this jump in noise is not noticeable unless you really start benchmarking each range - the attenuation value is another tradeoff, this time with maximum measureable voltage.
Great videos!
Hi, did you got something from TI regarding input capacitance tolerance of BUF802? Seems that is huge like 20% they reply to me in the forum.
That sounds about right, you'll either need to trim for it, or drown out the variability with more capacitance in parallel (like in this design, as scopes need ~15pF to work with passive probes)
True Hero ❤️
great .. pls dont stop the series ... hopfully there will be soem videos on the software and firmware side as well
Since this is open source have there been any considerations in translating the project into kicad? Altium is a bit less accessible to the home market.
We are going to production with the Altium design to avoid the delay of switching, afterwards we will import into Kicad, polish and verify it, then continue the design there.
@@eevengers6330 I think that's fair. Altium also has good integration PDN and SI tools which could be useful lool
Thank you for these videos. Can you please zoom on the schematic when explaining things so we can better see ale the connections and values even on phone?
I am guessing the upcoming video about that amplifier is going to get into DC coupling and how the aux in stuff works in low frequencies?
Bingo, just uploaded it!
Wow, great project!
You don't gain up you amplify. Good video.
Hi Aleksa, you are using 8bits adc right? There is a reason you dis not choose 12 or 14bits adc from analog devices? Or you intend to leave this upgrade for later?
did you watch the video? He clearly states they are using a 13-bit ADC.
@harry3life yes i saw, but did not match with the PN here and on git.
@@fabioposser2 You are right the datasheet states it's an 8-bit ADC.
Hi! We are now using the HMCAD1520, a 12 bit ADC with an 8 bit mode - it is still 13 bit internally. The beta run was built with that part, I just didn't update the schematic - oops!
great work as always... for me the hardest is really install the software client... its not great if you cant install it lol keep up the good work
If your data processing/plotting hits the CPU limit, go GPU. Shaders can easily do "digial phosphor". OpenCL math can easily keep up with the data rate. Oh and maybe don't use gray background :D
Can we connect to a normal pc or Raspberry pi ?
Any normal (x86) PC will do! RasPi doesn't have the pcie lanes, but something like the NVIDIA jetson will work once we get an ARM driver
@@eevengers6330 really amazing to hear, hope it will come for budget section also, my well wishes with you 🌹
Just found this great video, will there be any development further?
Yup! Should have another video up soon enough with the new revision that has thunderbolt built in.
I didn't quite get it: Is the thunderbolt <-> PCIe board also your design or are you using some stock boards? I would be quite interested to build my own custom thunderbolt <-> PCIe board but I'm just a private person and cannot find any chip with freely available datasheet...
Couldn't get the info for the thunderbolt chip, so that board is an off the shelf thunderbolt to m.2 NVME board, mated to the main board with an PCB interposer (m.2 to m.2 on the mainboard).
@@eevengers6330 oh, thanks!
Fantastic project! Seems like the only PC-scope so far capable of unlimited and uninterrupted data streaming (if your hard drive can keep up). It may become a game changer for the analog video capture/archiving community. Is there any chance for a high-res version (12 or 14bit), even if it requires a reduced max sample rate?
Thanks! We use the HMCAD1511 ADC right now, it has a 12/14-bit drop in replacement (HMCAD1520) so a high-res version should be pretty doable!
@@eevengers6330 That would be absolute madness! And it's not even twice as expensive, but probably has a year lead time :)...
@@eevengers6330 can this be added to the schematic and firmware as well.
Hello Team , i am shreenidhi from Texas Instruments Product Definer from High Speed amps , can you let me know how to get in touch with you guys ...
Will there be a standalone PCIe version for those of us that don't have Thunderbolt?
Yup! We've decided to make a PCIe version for the crowdsupply campaign. It will use the same board as the Thunderbolt version, with a few modifications
@@eevengers6330 awesome!
will intel JHL series thunderbolt soc be integrated in it?
We will be using a module to provide the main board with Thunderbolt, this module uses a JHL controller
@@eevengers6330 cool!
Wow, it's a wonderful project. Thanks for share it
O man o man this is a game changer for smps and pwm repair technicians like myself who's test bench is so crowded by outdated test equipment. Congratulations and great choice hackaday .
Cool! But is it only me, but i would love to have a PCI-E variant aswell. Especially in LP form factor. So you can put it in cheap desktop hardware like the Dell Optiplex for example. EDIT: Saw that the prototype was full sized. But a 2 port version seems it would fit as a LP card. But I'm not an engineer. But hopefully someone who is think that is a good idea.
It wouldn't be difficult to trim the height to fit an LP profile, would probably just increase the width to compensate and gain space for the FPGA. I'll probably make an LP varient at some point if people are interested!
@@eevengers6330 Awesome! Hopefully it isn't only that would love one. I see the potential with using it on regular enterprise PC's and rack mounted servers. Combine it with a nice SDR and you have a small RF lab.
@@eevengers6330 I'd be interested in an LP version too, to fit inside my tiny workstation :-)
@@GuilleAcoustic Glad to hear it! We will make an LP version available after the initial Crowd Supply campaign, since it will require a new circuit board.
@@eevengers6330 , thank you, that's awesome ! I've been searching for a nice DAC/oscilloscope PCIe card for quite some time. Do you think it would be hard to have expansion/daughter boards to expand the PCIe LP version ? Something like an optional mezzanine board to make it low profile but dual slot ... thus expanding the available channels. Anyway, keep up the great work :-)
Very excited about this project. Looking forward to purchasing.
hello from Kingston ON ... any chance the PCIE version will also become available.. how wou;d one order it :)
Focusing on the thunderbolt version for the Crowd Supply campaign, but the current prototype hardware is a fully functional PCIe card, so it would be easy enough to sell as a separate version later!
@@eevengers6330 sounds awesome!
Messaged you about this, looking forward to buying it
