FNIRSI DSO-510 2-in-1 10MHz Handheld Oscilloscope DDS Signal Generator

I love this little oscope. Great price! Works well for car audio, and the signal generator is awesome for electronics troubleshooting! They make a wireless soldiering pen that’s awesome too! Definitely gonna buy more from these guys and the tech support is on point!

The scope is easy to setup and use, screen is clear and easy to read, its small and east to carry, its durable, and looks goodworks good

Solid pocket oscilloscope for $41, but keep in mind that it's a $41 scope. As with most scopes, the controls are confusing until you learn them. It's definitely not the most accurate, but it's a quick and easy way to see a waveform's shape and detect transients. Read the manual to learn how to set it up. It's good for basic automotive diagnostics. The signal generator does in fact operate up to 50 kHz, but as soon as you return to Oscilloscope mode the frequency turns back down to 1 kHz, perhaps due to lack of processing power or perhaps for driving the probe calibration signal. People complaining that the signal generator doesn't work above 1 kHz must be trying to measure the frequency simultaneously using this same device. Also note that the signal generator's actual output frequency is less accurate at higher frequency setpoints, with the most heinous error being an output of 44.4477 kHz at a setpoint of 44.000 kHz (see attached pictures); output is dead-on at 40.0 and 50.0 kHz, though. Signal generator voltage outputs are also not completely accurate (note 2.54V p-p measured at a setpoint of 3.0V p-p). This is good for learning and basic diagnostics, but rely on something more powerful for the high-importance troubleshooting. It can trigger on transients, though.

works well

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.

Does exactly what it says it will do. I purchased this oscilloscope for car audio tuning and it has helped tremendously. Recently, I was able to determine an amplifier was capable of producing almost double its rated output, because I was able to see where the signal clipped rather than just use a basic formula to calculate the target voltage. Screen is bright and easy tl read. The ground lead fell off but I was able to solder it back together. I take it with me everywhere in my truck, light and easily moved. This about 2"x2 2" small

I have a $2500 snap-on oscilloscope and I end up using this more than more than the high end on.

Complete newbie when it comes to oscilloscopes but the hardest part about this was figuring out the top right adjustment also had a click/push in feature to select menu options. This DSO-510 can’t be beat when it comes to figuring out a clean signal on car audio builds. Simple and amazing 👍🏻

Nice and good

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.

Cumplió lo que prometió a un precio justo

Pésimo, me llego usado y sin la probeta para el oscilloscopio

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