DSO-510 Handheld Oscilloscope/DDS Signal Generator 2 in 1, Digital Portable Automotive Oscilloscope 2.8 inch TFT, 10MHz Bandwidth, 48MS/s Sampling Rate, Trigger Function Auto/Nomal/Single

Like most oscilloscopes, it will take some time to get used to the user interface and controls. Once you're familiar with it, the functionality is quite impressive for such a small product! All of the oscilloscope and signal generator functions I tested work well. The screen is easy to read and has adjustable brightness. Overall, I'm very pleased with this device. It's become one of my must-have items in my electrical toolbox. The instructions were not very clear about how to connect the oscilloscope probe and signal generator wires (alligator clamp type). There is a small metal adapter you must connect to oscilloscope probe before connecting it to the left port. The signal generator wires connect to the right port.

A little tricking to learn to use and easy enough. Works well and render good info in the graphing. Great price.

This is an OK digital scope. It works well for car audio applications, and maybe some signal diagnostics. It is not super accurate with the measurements, but it is good enough for basic stuff. The signal generator is also convenient but basic and also not very smooth. Overall a good value for what it is. Definitively not a high end scope, but functional.

This is a great product. It eliminates the need to buy conventional, relatively bulky test equipment (oscilloscope, audio generator) for servicing most audio gear. Shipment was super fast.

I need an O-scope to troubleshoot a 5 volt signal on a ford cam sensor. Although I knew the screen would be small it was surprisingly clear and it got the job done. I’ve used it several times since so it’s a great add to the tool box

Alligator clips work fine, but probe does not. The probe does not read anything. Update: Seller reached out and made things right. I purchased a new unit and it appears to be an updated batch. The screen panel and UI look slightly different than the first one I received, and the probe works fine. The calibration screw on the probe is very finicky; I do not expect it to last long before it is rendered useless. However, the oscilloscope served its purpose and will have its place in my toolbox for future projects.

Easy to use an exactly what needed

Very Low quality. The thing feels like a child's toy it's so light. The electrical connectors are so tight it feels like you'll break them when trying to attach them, and the software was obviously written by someone who's never touched an occiloscope in their lives. In my humble opinion, it's not worth ten bucks, let alone $40. Spend the extra money and buy a used Rigol, you'll be so much happier.

Nice and good

Cumplió lo que prometió a un precio justo

Pretty cute and so far working nicely. Nice product in this price.

The best handheld oscilloscope to have under small budget. Using this Oscilloscope for a few months now and it works good and perfectly measures waveforms. It has a good bandwidth allowing us to measure RF signals too. There is no fear in measuring mains voltages because it is handheld and has no ground connection. Downsides: 1. Function generator is tricky to use. 2. Supports only one probe. 3. Trigger mechanism is tricky to use. 4. Non customisable voltage multiplication factor. But overall this Oscilloscope is best for hobbyists and engineers who are looking for an Oscilloscope in small budget.

Bit small than I expected. But works good. No issues.
