To zoom in, once you acquired the signal, you have to go to the time scale selector and start lowering the value till it starts zooming. It's quite strange that at the first scale change it won't zoom in just after you lower the scale a few times. But it zooms in perfectly.

Thanks I've seen the DS202 work and I love this little scope for quick audio or even maybe some automotive work. Where crawling around under the dash or awkward positions would be a big help. I agree with you 100% this is not a bench scope, but it could be used for lower frequencies if that's all you have. The a few topics I didn't hear you discuss was the battery life or how to charge it or if you can put a power adapter on it, and if the software can be updated. I just purchased mine based on what I saw of a friends DS202 over two years ago, hence that's why I visited your video. Thanks for the posting and your hard work. Best Wishes n Blessings. Keith

I did not cover the battery live because it is not easy to measure because of the auto-off function. But in my scenarios, it was never a limiting factor because I was able to use it for hours. So, I could have mentioned at least this fact, you are right... I did not try to update the software because I did not bother and did not want to brick the tool. It works fine as I have it for now. So, I also did not want to give "untested" recommendations.

Perhaps worth to mention - this thing is also known as DSO Quad, with helpful documentation & resources here: wiki.seeedstudio.com/wiki/DSO_Quad I myself found the UI nearly unusable - but i replaced it with an alternative firmware, which i found to be much better. Btw, it is also possible to run other apps on this thing - i found the logic analyzer quite useful...

Gets embarrassing to seem to be a shill for Wildcat firmware (which is free, written by the community). Bandwidth on the earlier hardware combines two channels if you want, and uses that 72 msps to get to display a waveform up to about 13 MHz. I haven't fully tested the FFT function but in theory that can give frequency components up to the sampling rate. Does waterfall displays too. I hadn't used my dso203 for a couple of years, but now it is definitely in use as it does things my tabletop scope doesn't do, and at about 7 MHz bandwidth it is "good enough".

It could be very nice to see a review of a cheap but still good oscilloscope that you can use when you are working on cars. Besr regards

Ive searched high and low for a good osilloscope , eventually I bought a velleman HPS140i , it only had one channel but dat didnt matter to me As much as a high voltage input , the velleman has 100 volt input tolerance so with the x10 button it could be 1000 volt , the device is also a Cat 1 so it is safe to measure behind a fuse in 230 volt systems ,

I rarely use it like you when I am mobile, or when I want to avoid ground references. So I do not know.

Wildcat firmware written by the community and a big advance on the original, is difficult for people to 'find' to load it. Basically you download a big text file which is actually a hex file, then rename it appropriately and use it to flash the ROM. Any difficulties get back to me here and I will give details.

An improved software version is available called Wildcat. (my version is 5.6). Search under Wildcat dso203... The manual for wildcat that I have is long on text, nonexistent on graphics, but it explains what to do very well. Wildcat doesn't just do scope functions - it also does fft, serial signal decoding and other functions, which make it fairly awesome !

Great little tool I bought long ago (my first scope, and it saved my day more than once! ). I then bought a basic rigol scope later on, mostly because the DSO interface is hellish -- and even tough I upgraded the firmware to a better one (not to the latest though). But the DSO still is very convenient to observe signals in the field or far from the mains. Now a big issue is that my screen soon started to flicker as if the lightness was pushed too far while the contrast was reduced. Then the problem worsened to the point the screen is permanently and barely visible! :( The nice thing is that the schematics and code are open source. The bad thing is that I really have no clue how to fix this (defective screen controller?!)... and it looks like I am the only one to have experienced this issue :/ As seen here: plus.google.com/+JeremieFrancois/posts/bWnPYSCpdaB

Hoi Andreas, cooles Viedo! Ich habe mir so ein DS203 gekauft und brauche es für die Fahrzeugelektrik. Ich habe probiert ein Sekundärzündsignal aufzuzeichnen aber habe es nicht hingekriegt! In der Regel kann man das Signal über das induzierte Magnetfeld auf der Zündspule messen. Liegt das an den 72 bzw. 10MHz? Oder habe ich das ding falsch eingestellt? Freundliche Grüsse nic

@AndreasSpiess

Da kenn ich mich zu wenig aus. Grundätzlich würde ich schauen, ob das Signal im angezeigten Spannungsbereich liegt (schau auch, ob dein Tastkopf auf x1 oder x10 eingestellt ist. Wenn es kurz ist, ist der Trigger level und die Richtung wichtig. Un dann kannst du ja auch noch die Speicherfunktion verwenden. Zu den MHz: Ich glaube, dass du zumindest etwas sehen solltest. Das Signal sollte nicht so schnell sein.

Great review! Question - The majority of my technological expertise is related to Linux, software automation, web development (mostly server side), and other similar software. However, I'm starting to delve into your realm, electronics. Thus far, I've worked with the Raspberry Pi quite a bit, and I'm now starting to get off the ground with Arduino. So, for the question - As far as microcontrollers go, I consider myself a novice. I'll be prototyping some projects using Arduino and teaching myself how to do so. My knowledge on oscilloscopes in general is pretty minimal (I've never sed one, but I am familiar with the basic operations and what they're used for. With this in mind, do you think this is a good oscilloscope for someone in my shoes? Or would you suggest one of the more expensive $350+ desk units? Thanks! P.S. - Subscribed! P.S.S. - I realize this was posted ~2 years ago. Is there a different oscilloscope in the same league as the DS203 that you would recommend?

Welcome aboard the channel! Since the oscilloscope is one of the most important tools in hardware development I would not go for such a small one as my main one. One of the best deals seems to be the new Siglent SDS 1000X series. It might be in the range of 400 $. If you stick to the hobby you will not need a new one for many years to come...

Thanks very much. Have you seen a similar oscilloscope that is maybe a bit easier to use, and perhaps a bit more expensive? In addition, have you seen anything that can use a tablet as well as some hardware? I am thinking of the picotech products that use a pc. They are really good. When you are away from your lab, you will often have a tablet, so hving something that integrates with that could be very good.

@AndreasSpiess

I did not see oscilloscopes for tablets, but I did not search for them. Your other choices are: Desktop oscilloscopes or boxes which are connected to a PC using USB. Both have a simpler user interface because they are bigger.

So far I have no such plan.

I have an extremely cheap diy oscilloscope, a DSO138. I've found it useful as a diagnostic tool in analogue circuits for situations where a multimeter is useless but accuracy and sample rate are not critical. My main complaint is the lack of a rotary encoder, and that seems to be a downside to the DSO in this video. Clicking buttons for adjustment is neither fast or accurate, but has to always be some compromise between the fast and accurate.

It has the limitations described in the datasheet. For simple things, this oscilloscope works well. If mobility is not a must I also would look at cheap desktop oscilloscopes.
