3 in 1 Oscilloscope, 40MHz Oscilloscope Multiumeter with Waveform Generator

I took a chance with the 40mhz version and I am extremely happy with this unit. It's super portable, accurate, and easy to use. Perfect for field use. Doesn't have as many features of bench tops, but that's not it's point. Pitted against my certified calibrated Fluke 789 (voltage accuracy test), this thing is on the mark accurate. As stated by others, when in auto range, it's slow to settle, but when locked in a range, it's nice and snappy. This will perform just fine for troubleshooting in the field, mainly for discovering intermittent DC voltage drops/issues with industrial equipment and sensors (something DMMs can't do). Although the DMM test leads it comes with are worthless, those are easily replaced with better built leads. The probes are good, no picture but it performed well when connected to my signal generator with a 1-40Mhz sweep, begins to struggle a bit above 35Mhz, but that's beyond the scope of my needs for it in the field. Although it's ability to survive an industrial setting is yet to be determined, I'll take my chances and just treat it with care. For the price you can't beat it.

Love this little o-scope! I purchased the 40MHz version with the signal generator several months ago. I've used it extensively for prototyping DIY synthesizer builds. Indispensable and effective for viewing audio frequency waveforms and their voltage levels as I'm far from the 40MHz spec. I use the signal generator to produce known waveforms and view them post op amp circuits. Great having additional multimeter and other functions built-in and to be able to rapidly switch between them. Very intuitive, easy to use and small footprint on my workbench. Excellent value overall compared to almost any other o-scope option, as I couldn't justify $400-$1000 for a full fledged.

Display is plenty bright and clear with decent colors and contrasts. Decently easy to switch modes and when you switch out of signal generator mode it stays operating for you to do tests in scope mode. Also the scope does a decent job displaying even small amounts of distortion or waveform abnormalities.... But there are some menu options and settings that probably aren't in the easiest places to find. Also there are some meter selections that take a good few seconds to finally display a reading. Every range was very accurate when comparing against known values tho. Also the battery life could be better especially since it's display times are set short before going to sleep. At least it's rechargeable and can be operated while charging. Also the case seems pretty rugged, not cheap. Same with the leads. The back stand could be a little more sturdy tho.

This unit is great. I read reviews on this and the hantek. I went with this for the bigger screen. The specs are better to. Its very fast when you turn it on. The display is very easy to read and the controls are intuitive. This is now my go to meter for most things around the house and camping. All and all, for the price, you get a very practical and useful oscilloscope and DMM.

This thing is awesome! Meets the needs of a hobby level user and more. Love the feature set.

Accuracy is as good as my real oscilloscopes and the ease of use of this makes this a go to for me. I originally ordered this only because it is not tied to any grounds, but now use it as my favorite desktop scope. I am a longtime EE and am using this happily with 5 kHz - 20 MHz signals and am also very happy with the function generator. Highly recommended based on price/performance.

Changing functions is just too cumbersome. Very non-intuitive. This scope could have been engineered to be much easier to use. Button presses and button combinations kept me referring back to the manual each time I used it.

Well made Screen is a little too small Software works but isn't particularly friendly. Battery life is OK. Generally, last all day. Comes with many extras.
