Spike Capture with Oscilloscope Deep Memory
Вставка
- Опубліковано 16 вер 2024
- This video is illustrates how an Oscilloscope's deep memory is used to capture a spike found on a sign wave, and how it can be captured using an oscilloscope without deep memory. A Keysight EDUX1002 is used as well as a GW Instek MDO2204EG series scope and a Siglent SDS1202X will also be used. #deepmemory, #howtouseanoscilloscope

Another very good video. Well done. I like the way you explain those things. I like these type of videos pretty much as they are very useful for many hobbyists I guess and people can always learn something from it. At least I do. Thank you for sharing. BTW I am using the Keysight DSOX 1102A (100 MHz, without the function gen) and the SDS1104X-E which can do Bode Plots when used with a Siglent function generator which I have. I am also using the bigger Siglent SDS2104X (100 MHz, 140 MPoints !!!) Finally, I also got a used Siglent SDS1202X-E with the 200 MHz. Like Oscilloscopes, apparently ;) Using them a lot in my AVR programming and Arduino/Raspberry Pi projects (controlling stuff, measuring more stuff, running my Raspi Parallel Cluster self-made out of 15 single Raspi Pi 3B+ units). The latter is also a good reason why I like your videos on power supplies and DC-DC converters and such alike. That all fit into what I do sometimes in my projects and circuit developments. Hope you‘ll get increasingly more Likes and subscribers to promote your channel.
Markus Keller Thanks so much for your support - I really appreciate you!
I think you might like scopes;) all very nice ones as well! I knows who to contact if I need programming;)
I hope to hear more from you - and let me know if you have comments, suggestions, or questions.
@@KissAnalog Hi Eddie. If you're looking for help sometime in regards to programming, yes, let me know and I will be more than happy to help if I can. At least I am quite familiar with Python, C/C++, Perl, Java, Lua and a few others over the past 15 years or so... :)
That's how to do it! I really like your subscribe screen, wary clear and something you notices!
I did also really like the short form about Patreon and Amazon. You tell that it helps, but without using more time then necessary and it do in no way become annoying but instead stand as a personal "help if you want"
Also great demonstration, logic idea to use the trigger to only stop at something that goes outside normal signal. Unfortunately is it not to much help if the glitch is inside the normal signal:-)
Fried Mule Thanks for the great feedback Fried Mule! I’ll keep working on better ways;).
Yeah - the spike is much easier to find with deep memory - especially if it’s hard to trigger on😬
That's a clear demo of why additional memory is beneficial. I really don't understand why Keysight limit it so much given that it's such a low cost element in what is otherwise an expensive piece of kit: no one buying it is going to notice the extra couple of bucks for 30MB of ram. Their marketing dept really has to go to town to proclaim why it's not necessary! The triggering options on modern scopes are great as well. I volunteer as part of a team looking after a rebuild of a 1940s machine which is full of mechanical relays and commutators and the signals are very noisy. Tracking down a spurious pulse amongst a large amount of glitching and noise was nigh-on impossible with an old Tektronix (it still has a 3.5" floppy drive for screen capture!) It offered triggers such as Edge with a choice of rising or falling, as well as....well, nothing else, that's it. You can imagine how difficult it is to trigger on a pulse that is the same voltage as the glitches: basically, it just required good luck. With the Siglent, we just tell it to look for pulses of a certain duration (>5ms) and all the noise and glitches are ignored. Then it's possible to zoom in and out on the detail. With little memory, that just wouldn't be possible and we'd never have been able to make a start on tracking down the culprit. I don't think it's possible to appreciate how useful a decent amount of memory actually is until you have to use it in real-world problem analysis.
Andrew Johnson I’m so happy you share this experience! I’ve been there too - and loved the old analog CRT scopes that took real experience to use to track down these problems. Today, with a scope that has deep memory, and some knowledge (which I hope to share) anyone can do so much! I too am surprised that keysight doesn’t just kill the market by offering so much more for so little more... Memory is so cheep, and they’ve done the hard work already - plus with their name - they would kill it! Thanks Andrew!
Thanks. Very informative. Subscribed.
Vital Ral thank you! I’m happy to have you;)
Hi Eddie, impressive.
versace885 Thanks so much!
I purchased a SDS2202X-E (200 MHz) with 24 MB of memory. I hope, as a hobbyist, the FFT meets my spectrum analysis needs.
Those are great specs - I think you will be very happy! Thank you for sharing this;)
This video comes in handy , since a few days i notice a glitch in all my led lightning arround the house, the glitch occurs when the ignitiontransformer of my gasoline burner (central heating) stops when the burner is running.
It seems that there is some sort of flybackvoltage kicked back to my main lines.
Wow, did you find the problem? Thanks for sharing this!
@@KissAnalog not yet, i'm still working on a scope probe with a right attenuation for best results on measuring mains. I hope to have a answer soon, and will post back the results. Thx for replying. Greets from Belgium
Interesting video, keep on!!!
Appreciate you!
8 bit ADC's in most scopes. The voltage readings are almost always a bit off. They are close enough.
Thanks Jeff! Yes, 8 bit has been around for a long time and usually only the more expensive scopes have high bit resolution. I just did a review of the Pico scope which has 12 bits: ua-cam.com/video/vFRvdYTCkx4/v-deo.html
after watching this, i think i'll save my money for the rigol DS1054Z rather than Owon SDS1102, even though there's a sale for the Owon SDS1102 at 50% price cut, probably 2 more years worth of saving to buy the Rigol, right now i'll stick with Hantek 6022BE with open-source software because the original software is not usable..
Seraph Hi Seraph, I think I’d recommend the GW Instek. Have you watched this video?

HI Eddie, good video about deep memory :-).
I am in doubt which scope I should buy : the SIGLENT SDS1202X-E or the new RIGOL DS1202Z-E.
Both have deep memory : Siglent 14Mpts and Rigol 24Mpts.
But the waveform capture rate of the Rigol = 30.000wfs/s and the Siglent = 100.000wfs/s.
All other parameters in the datasheets seems about equal.
Which one do you prefer or recommend. ?
Perhaps a good idea for a comparaison between them in a video ?
Thanks Vic! I like the video idea! Great comparison, and I might have a 3rd option. I’ll see if I can get something out this weekend;)
@@KissAnalog Waw Eddie that's cool, I guess the other followers will find it also interesting :-)
Espectacular, de verdad me esfuerzo , es otro idioma. Ojalá pudieras enviarme uno jeje
I wish I could;] thanks for watching!
@@KissAnalog No hay problema, suficiente con el conocimiento que comparte. Gracias ✌
Super Eddie
Bert van Lelieveld Thanks Bert!
