I've got one, personally i don't like it but I'm willing to say its due to the lack of documentation. autorange is very slow, infind it hard to scale.
Website is really screwy, hard to find the files needed to update. I do have the files now and did the upgrade to V1.96 2023/12/07, works ok.
Hi - what does the firmware upgrade add? Does it include FFT capability?
Hi, where did you get the firmware and how did you update it? Thanks.
@@bobisyouruncle1 The author of the software is Tianping Guanghua, he is registered on the Baidu platform. We need to contact him so he can add FFT!!
This site has a link to the baidu disk there at the moment Software Version: V1.98 (2024/03/04)
@@Koddra scan the qr code on the manual or the box you get the oscilloscope in.
If this oscilloscope really has 10 MHz bandwidth, then I'd really like to see how it displays a 1 MHz square wave. Square wave is the best test signal for an oscilloscope. And there is no need for unnecessary words.🙂
I have not tried to measure 10MHz, but I have measured sine, triangular wave and PWM up to 1 MHz and it is visualized satisfactorily, there is no basis for comparison with more expensive devices, but for amateur prices it is excellent.
@@hobbyelectronics1995 In any case, I would like to look at the 1MHz meander. This is a very broadband signal and therefore it is it that reveals the real capabilities of the oscilloscope. In addition, rectangular signals are extremely common today. These include PWM signals and all kinds of data transfer protocols. Therefore, it is important to know what the limiting frequency is at which it will still be possible to distinguish a rectangular signal from any other on a given oscilloscope. And in some cases, not only the displayed signal shape is important, but also the actual measurements of the duration of the signal transition to one or another level. That's why it's interesting.
write me what exactly you want me to test, I was interested. but i have a generator up to 1 MHz.
@@hobbyelectronics1995 Please test with a meander. You can set the frequency to 10 kHz to begin with and gradually raise it to 1 MHz. It is best to do this in steps: 10 kHz, 20 kHz, 50 kHz, 100 kHz, 200 kHz, 500 kHz and 1 MHz. This way the video won't be very long. I am more than sure that I am not the only one interested in how this oscilloscope displays square wave signals.
Will it capable in testing current by putting uni T clamp on the probe. Hope you can do a video for that
Could you please test with square waves of 2 and 3Mhz?, 3 or 4V. Thanks!
I have one of these - seems pretty good for what it is - general audio work in my case.
Did you figure out the upgrades? It only seems to go to a mobile webpage via the QR code and the .rar file I find does not open.
settings are clear, works very well for the price. Their web site is not good, but it has all the files in .rar format, so everything is correct for me.
good product
Can it do single trigger events?
Can someone point me to a copy of your manual on the web please? Mine has no manual
Hi, do you know where i can find the firmware for this oscilloscope and a tutorial on how to download it? Thanks.
Hello! Firmware update V1.98 (2024/03/04) has been released for the Engineer SCO2 oscilloscope! I made a post on Reddit so that the guys could help me download from the baidu!
@@master_codings I actually wrote a message to the OP of the post (Appropriate-Text-244) so not sure if that is you but I am still not fully sure on how to update the firmware on the oscilloscope from my computer so i would be glad if you could point me to a tutorial or something similar. Thanks for the reply.

hi! what is voltage sensibility? 10mV, 20mV?
i don't remember exactly but it's either 20mV or 10mV. for sure 20mV is possible but for 10mV I am not sure.
What is the minimum volts/div (sensitivity) ?
Are there cursors to measure?
Yes.
In your opinion is it worth buying
it depends what you expect. for amateur purposes it will work. the most important thing is that it has two channels.
Am I able to take screenshots with it?
No.
Good question! Now I know that I don't want to buy this toy... So I will buy DSO2512G
