Customer Reviews for VEVOR Digital Oscilloscope, 1GS/S Sampling Rate, 100MHZ Bandwidth Portable Oscilloscope with 4 Channels Color Screen, 30 Automatic Measurement Functions for Electronic Circuit Testing DIY

This device had more abilities and functions than I imagined. It did exactly what I wanted it to do but is capable of so much more. I am still learning all of its functions. A great piece of equipment.

I liked that this product is easy to use.

On-time delivery, good quality and service. love the local warehouse service

This is a very impressive device. It is basically a multimeter with a built in Oscilloscope function. It is very well made and looks sharp. It runs from three AA batteries included, and has a soft storage sack and tow test leads. The display is backlit and is a high resolution matrix type to display the readings and units. If in a voltage range you hold down a button and it switches to an Oscilloscope display. It does come with a fairly extensive 29 page manual that seems complete and well written and not some weird translated thing I have seen with other equipment. I have not gone through all of the functions yet to put it through all of its paces. This seems like a very good multimeter, and sometimes you really need to see a waveform to really know what is going on with more than a dc circuit. This gives you that capability in a single tool. Recommended.

I am not an electrician, electronics engineer, or even an hobbyist when it comes to tools like this, but I got this tool to help me find issues with my 3d printers, check unknown outlets, and to verify my work on 3d printers that I will be building. So far it's good enough for my amateur needs, and I am not expecting a high degree of accuracy with it.

I was very excited when I saw this thing pop up so figured I'd give it a try. For reference I'm not an EE, but I build guitar tube-amps for fun, so having a non-mains oscilloscope is a great thing to have and of course a multimeter is always welcome. My first impression when taking it out of the box (and the bag, which is NOT a case and will not protect the meter from anything but minor scratches) is that the meter feels cheep. I handed it to my non-technical (but adorable) wife who commented without asking that, \"it feels like a toy\". One drop on a tile or cement floor and I imagine this thing is toast. This ain't no Fluke, but then a Fluke scope meter starts at $2000 so that's not a fair comparison. As a meter, it's fairly intuitive if you ever used a multimeter before. The dial sets your mode and you have different lead connections for high-amp current testing and for capacitor testing. No issues there. The readout is a bit unique with all of the main readout numbers being hollow and that seems like an odd \"form over function\" choice to me - make the numbers bold and obvious! For simple measurements this thing does the job, but then so does a $10 multimeter. How about the scope? The scope works. I hooked it up to my Agilent arbitrary waveform generator that has absolutely not been calibrated in probably 20 years, but that's not important because I'm not building satellites. That's when I hit the first snag. How do you enable the scope? There is no scope button, and absolutely no obvious way to start the scope, so I did what any man would do as a last ditch effort to get something working: I checked the manual. Ahh - hold down the R button for two seconds. Um. OK... now there's a scope. I set the Agilent and looked at the screen and saw a very tiny trace. How do I set the scale? No idea. How do I set the voltage range? No idea. How do I set it to auto? No idea. Oh wait - there are four function buttons and one of them is time. Nice! I am treated with three op
