Reviewed in the United States on March 4, 2024
I tested from very low frequency to over 100mhz and works good. Triggering good and I prefer small scope with buttons than small scope with no buttons and only menus. Also appears to be accurate for frequency and amplitude. Easy to read display. Comes with x1 x10 probes but no compensation. For this price it is ok and I already have probes with compensation. I wish it came with case.

I'm extremely happy with this scope. It's very simple to use, veyr accurate, great price, great quality screen, durable, USB-C charging, I'm not sure what more there is tk ask.

This product is adequate. It doesn't compare to oscilloscopes for just a small amount more money. It is complicated to use and resolution is not what it should be. Other than that it gets the job done. But only if you can actually get the item. This was a nightmare to get in the first place! It took over two weeks and 4 phone calls to Amazon, plus a replacement because Amazon "lost" the product. I lost customers because the item took so long to arrive, they went somewhere else. But Amazon did say they were sorry for that, and that is all they did about it. All in all, this works, but you can get an oscilloscope that does the same thing for MUCH less money elsewhere!

It is a very convenient size, compact yet still has a very usable screen. It takes up very little bench space. The controls are very intuitave and easy to use. The performance is adequate for almost all general oscilloscope use. The 3 in 1 multimeter and signal generator are also very useful.

So they at least say that this oscilloscope has a 2500mAh battery. But then in one place they say that a full battery can provide about 4 hours of continuous use. And in another place they say a full battery can provide about 6 hours of use. When it comes to how long it takes to charge the battery though, there's no information to be found. There is information on the charging rate of the battery, but it is not easy to find. Most places only give the volts that it charges at, which is a given anyway since pretty much every device that can be recharged charges at 5V. However, I did manage to find in the instructions that the charging current is about 700mA, which I believe would be about 0.7mAh. And so, that would mean that this oscilloscope charges at 3.5 watts, which explains why it took over 4 hours to charge when I got it, which would then explain why they weren't forthcoming about it. I wouldn't be making such a big deal about that, but considering what this device does? I would think it would have more detailed information about how it charges than most other devices that are rechargeable.Anyway, regarding the pictures I've provided. One picture shows what comes with the accessory kit. One picture shows the multimeter parameters. One picture shows overall parameters. And the other picture shows the probe specifications. I uploaded these pictures to help anyone who needed more information about this multimeter/signal generator/oscilloscope. And so, I hope they at least help someone out there.As far as how this device functions, it seems to function quite well so far. So I would have given it 5 stars if it wasn't for the lack of information regarding how long it takes to charge and it's varying information regarding how long it can function with a fully charged battery. That is why I have taken a star off. If you have gotten this oscilloscope, just know that when you are charging it, if the red light is still on it is still NOT fully charged. You will know when it is fully charged when the green light is constantly lit. Also, the instructions say to not use the multimeter while it is charging. And besides that, the instructions say,"When measuring high-voltage or non-isolated circuits, it cannot be used while charging (powered by a built-in battery)."I put that in quotes because that's exactly how the instructions put it and I'm not sure what to make of it, lol.

This looked like a pretty good portable scope and DMM so I ordered it to supplement my existing array of hobby electronics tools.I was going to test the scope with my bench waveform generator, but when I went to turn it on, it was completely dead. So instead, I used the built-in signal generator on my Rigol bench scope (which maxes out at 25MHz for a sine wave). I included some photos of the mini-scope showing various signals from the generator, and some showing the waveforms on the mini-scope and the Rigol at the same time.This mini-scope has an interesting ability to show both a waveform from the scope and readings from the DMM (separate probes). You can also switch the DMM to a full-screen view if you aren't using the scope.I ended up using this tool to try to do some troubleshooting of that dead function generator. I checked the waveforms of the bridge rectifier portion of the AC input side of the power supply, and also checked the DC voltages of the outputs of the SMPS. When the main board of the function generator was connected to the SMPS board, I was seeing strange voltages at the output of the SMPS. I thought maybe the SMPS was failing, so I disconnected the main board and when I did this, I was able to determine that the output voltages of the SMPS looked good. This led me to believe that the main board may have an issue (or the SMPS only works when there's no load on it). I did all this with this mini scope!Overall I am happy with this tool. I wish it came with some sort of storage bag or case, but I will probably just use the box it came with, since it had a foam liner to keep everything organized and protected.
