Review: Solid - Bought because I dropped a hammer on my crappy multimeter and I've been looking for an excuse to get a new one, I really wanted an oscilloscope too but we all know how expensive they are. I honestly don't really use the oscilloscope feature a whole lot but I have used it once or twice and it works pretty good, the user interface is a little confusing but once you know how to use it it's great. I wish the packaging was a little bigger because after you take all of the accessories out it's kind of a pain to get them back in addition to the DMM. Multimeter does exactly what it says it does, It works. My only real complaint about the whole thing is that the screen turn off time sometimes gets in the way of something that I'm doing, I think you can turn it off so that's not really a huge issue but also it's not very good with when the sun is reflecting off of it, I usually have to find a specific spot for it when I'm doing something or else the reflection of the Sun will just make it completely unreadable so I just keep it in the shade most of the time. Overall it's very solid, works great, I don't know if there's any type of circuit protection built into it but I feel like they're probably is because I've definitely done some things at some point that should have popped a fuse but it just didn't, very nice device and honestly My only regret was not getting the highest tier one even though I'm sure I wouldn't have used whatever that extra thing was, I'm just like that I guess. 10/10
Review: Wish I found this unit years ago. - Great device with a lot of little things other units I tested just did not have or work very well. It has rechargeable battery's that are easy to get to and replace and find online. Unlike some units in this price range you can use all 3 modes at the same time. The AUTO mode works great while still letting you tweak things to your liking. The user interface is super easy but still gives you a lot of options. Double click a button pops up menu 0-9 so you can type in the freq and so on. No need to hold down for ever to get from 20 to 20k. You can recharge the batt and use the unit at the same time. !! DANGER, you are EARTH GROUNDED when charging with a pc or charger with 3 prong power plug !! !! PLEASE read up on this on YT before you charge and use at the same time !! This was my 4th unit that I tested before finding this unit and I love it. The others just had too many little things missing or a PITA user interface and NON-user replaceable rechargeable battery's or non-rechargeable battery's.

## Questions & Answers

**Q: Is the included probe 10X?**
A: The package includes 1 peace of 10X probe. And it can be used with 100X probes(such as Hantek T3100), which is not included in the package.

**Q: Can use this to determine the Total Harmonic Distortion from my whole home generator?**
A: Dear buyer,
Good day. Thank you for your asking. Yes, this scope can do it as your require.
Thanks and have a nice day.

**Q: Why not explain the difference between the four models?
one is 40mhz, one is 70mhz.
one variation has arbitrary wave generator, one does not.**
A: Dear buyer,
Good day. Here are 4 difference models. 
2C42: 40MHz and has not wave generator
2C72: 70MHz and has not wave generator
2D42: 40MHz and has wave generator
2D72: 70MHz and has wave generator.
 Hopefully this answer is helpful.
Thanks and have a nice day.

*by C***S on July 13, 2021*

Update: Somehow I recently discovered and then purchased the Owon HDS272S. Credit to Hantek for creating this market segment but Owon is clearly the better buy right now. Though there are some pros and cons. Hantek Pros: -More rugged feeling -Bigger semi-rigid case (Owon case barely fits accessories) -A couple AWG operating points the Owon can’t do (faster square wave) Owon Pros -Bigger screen, more memory, faster waveform updates -Faster and better interface overall -More measurements, better measurement display -AWG can go to lower voltages -Lower noise on small signals (see picture) -Better DMM, fused current Old Review: I'm a EE who designs circuit boards and uses scopes regularly. I've used other Hantek handhelds, Siglent and expensive Tek and Agilents. I finally decided to buy a scope for myself and this is what I chose. Knowing I don't have much time for home project I didn't want to spend much. For the price and features (AWG) this looked like a good start. If I ever added a bench scope this would still be useful (battery scope are isolated by nature which can be a big benefit). I spent a little time comparing this scope to 1Ghz Agilent and have some takeaways. Overall the waveform generator is solid up to the allowed frequencies. The Sin attenuation at 25MHz was maybe 30% (expected) and the waveform looked good. Square wave had some overshoot but solid rise times (compared to period) at 5Mhz. Overall pleased with the AWG. The scope performance was ok except for one main issue. My unit has a frequency dependent offset problem that's worse on channel 1. As the measured frequency increases above 1Mhz an offset develops. When the Agilent scope was reporting a +/-2.8V sin wave the Hantek was saying +3V/-2.6V. I saw this problem playing with the scope alone but wasn't sure if it was the scope or AWG until comparing against the Agilent- it's the scope and further experimenting showed its worse on one channel. Self cal didn't fix it. Otherwise scope performance isn't bad. The trigger isn't as solid as I'd like - its always jumping between 2 pixels. Low amplitude performance (0.1V sin wave) compared decently against the Agilent and overall amplitude accuracy across frequency (up to the AWG 25Mhz max) matched the Agilent well (setting aside the above mentioned offset error). Functionality is simple and covers the bases well enough. Its disappointing there aren't more measurements like RMS (measurements are all or nothing and there are only 3 each) but otherwise It's not missing much I was expecting. Using it is easy enough with a few quirks (I can never remember what up/down does vs left/right). Overall I'm happy I bought this and its a useful tool. If it wasn't for the previously mentioned offset problems and a couple other quirks (sketchy unfused 10A DMM current) it would get 5 stars. As it stands this is 3-4. I'm giving it 4 for the value. Final tip, if you're on the fence probably go with the 42Mhz version. With this sample rate the higher bandwidth will rarely be useful (and not possible when simultaneously sampling 2 channels).
