FNIRSI 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

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

Slick little product. It gets a job done. Not all the jobs maybe, but a job, certainly. The frequency generator is a nice have, and the fact that it will run independent of the scope side is great, and makes it a truly useful piece of test equipment to have. I don't know what the actual adapter is for the cable, but it would be nice to have something a bit nicer than common alligator test clips for signal injection, though, you can always clip it to a dupont cable if needed. Also, the value for cost is absurd. worth double.

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.

Nice for the price

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

Easy to use and I like how it works especially for the price, but switch the 1x and 10x attenuator on the probe doesn't do anything to the input signal. Seems to be broken.

Great little single channel oscilloscope for the money. Took a little bit of playing with to figure out how to adjust the settings but it was super user friendly afterwards. If you do any kind of electrical diagnostic work, these are indispensable. Tracked down a crank signal issue in no time.

These oscilloscopes are garbage don’t buy them. I bought one and it works perfectly fine for the first couple times. But one day it decided to stop working. And I never got it to work again. The signal generator burned out. The oscilloscope trigger function it very unreliable at all times from new. I’m buying me a way better scope soon. The trigger function went off when I was playing with it. The crazy thing is that it wasn’t connected to anything while it triggered. And even crazier is that the trigger is set to 9.2volts when this all happened. MY ADVICE BUY SOMETHING HIGHER QUALITY! This is cheap Chinese junk.

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

Outstanding. Works like a charm.

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

Good working well
