6022BL PC Digital Portable Oscilloscope 16 Channels 20MHz 48MSa/s Storage Multifunctio Logic Analyzer Handheld USB Oscilloscope

Works great

This is very basic scope which will suffice for hobbyist and light lab use.PROS:- Inexpensive- Decent build- Ok probes- Doesn't take much space on the desk- App looks and works fine and doesn't appear like typical half-translated Chinese softwareCONS:- Absolute minimum feature set. Short of few measurements it's not far from the tube scope.- Logical analyzer is just a multi-channel scope for digital signals - no protocol analysis. This and above can improved in the software, but I don't keep my hopes high.- Can't combine scope with digital inputs - even my cheap pocket scope DS203 can do that- No power switch, you'll need to pull out USB connector when not in use. Has a button for switching between the analog scope and "logic analyzer". Interesting choice to place it on the back panel though.- English manual on the mini CD covers obvious things to no end, but doesn't cover the kind of information people would turn to manual to learn. I still don't understand the purpose of the second USB connector.Overall, no pleasant surprises, but for what it costs it's not disappointing.

it fits my requirements,best feature open-source community support, ongoing development Openhantek and Sigrok, and great features not found in the commercial software developed many years ago by Hantek.

UPDATE: After less than a year, I'm having more and more trouble getting this scope to boot. A couple of months back, it decided not to connect to my Android tablet. I connected it to my PC and it started working. After that, I was able to connect it to my tablet without any trouble. I checked and rechecked the connections but couldn't find a problem. Strange, but I was able to test what I wanted so I shrugged it off.Today I went to use the logic analyzer with my PC and the supplied Hantek software. Plugged in the USB cables, opened the software, and I had trouble getting the logic analyzer to give me a clean signal. I was testing using only a single channel but got digital hash on three separate channels. Checked and rechecked connections several times-- no luck.I glanced at the scope and saw that the power light was out. Uh oh-- I've been down this road before. I tried plugging/unplugging it while I looked at the Device Manager in Windows. It shows up as Unknown Device, not as a Hantek 6022, even though the Hantek drivers are installed and visible in Dev Manager.I tried plugging the scope into my Android tablet. HScope will not recognize it either. My Hantek 1008C is recognized instantly so it's not a problem with the tablet. As far as I can tell, the 6022 is dead. It's done this to me in the past-- failed to boot, then booted up when it finally feels like it-- but it's always annoying, and this time it's been out to lunch for longer than ever. I'm not optimistic that it will wake up, or that it will stay working if it does.I have to say, I'm disappointed. I used this scope just enough to appreciate its potential, but it never seemed to work quite right, and it's steadily gotten worse. I chalked it up to my old Android tablet, but my 1008C is lightyears better with the same tablet. After a year of working with the 6022's buggy firmware, its intermittent connections, and its general sluggishness, I'm dropping my rating to 1 star. As it sits, it is not a usable piece of equipment, and all the faults that I attributed to cables/tablet/whatever look like they're the fault of the scope. If you get a good one, you'll probably be fine, but if you get a bad one, you'll lose your mind debugging it.Original review follows:I bought this scope almost exclusively to use with the HScope Android app. For those who don't know, HScope is an app designed to turn an Android phone or tablet into a front-end for a digital scope. It's meant to be a low-cost oscilloscope package for audio work, automotive diagnostics (my intended use), etc. HScope is software only-- it still requires oscilloscope hardware to capture and input signals. The Hantek 6022BE and 6022BL are both supported by the app.I chose the 6022BL because it was one of the least expensive options that gets reasonable reviews. I am no longer a professional mechanic and this was sort of a shot in the dark for me so I didn't want to spend a lot of money unless I needed to. In all, I paid less than $70 for the 6022BL shipped to my door.The 6022BE version is more popular, but the 6022BL includes a logic analyzer. The logic analyzer IS NOT supported by the HScope app, but it is supported by the factory Hantek software as well as some aftermarket programs (I believe both Sigrok and OpenHantek support it, but I haven't looked into it much so don't quote me on that). I wanted to have the logic analyzer option in case I ever want to mess around with it, but it hasn't been a priority yet.My setup includes a 6022BL, an inexpensive (and old) Android tablet I had, and an external USB battery pack. The 6022 does not get its power from the USB port of the tablet, hence the battery pack. My tablet had trouble recognizing the scope the first couple of times I connected but it's worked fine ever since.So, how does it work? Well, HScope has a lot of features that make it particularly nice for automotive work. I can capture, save, and examine waveforms from a variety of sensors. Input is +-5V when using a 1X probe and +-50V when using a 10X probe. I also have 20X attenuators if I need to hook into something with higher voltage (for example an ignition primary, which can have an inductive kick of over 100V). The scope triggers reliably, even on single-shot signals.Resolution is 8 bit, which is not exactly stellar but probably fine for what I'll do with it. There is some notchiness in the traces, and I suppose it could hide some of the more subtle aspects of a waveform, but I haven't had any problems yet. I'm limited to 20 MHz (which is fine for my use) and 2 channels. 4 channels would be nicer, but until recently HScope could only do 2 channels. If I was buying today, I'd probably go with the Hantek 1008C, which is an 8 channel scope (only 4 are usable in HScope).The probes are fine for general use. They have a 1X/10X switch, and it's easy to forget to switch to the correct attenuation setting so be careful. Both probes compensated easily using the scope's cal signal and both work fine to pick up signals so no complaints there. I think you'll probably hit the limit of the scope's capabilities before those of the probes.Power consumption seems fine. I've powered it with a small external charge pack for a couple of hours at a time with no problems. I use the same pack to charge the tablet as I'm using it, so I expect to be able to use it for the better part of a day without any issue.I have not used the factory software so I have nothing to say about it one way or the other. Ditto the logic analyzer. I don't know if the included CD-ROM has any documentation, but I didn't even bother with it. The learning curve has been with the HScope software-- the Hantek itself is pretty much plug-and-play in my case. For those who are interested, there is a YouTube channel called Gadgets Playlist that showcases a lot of the HScope's functions. HScope also supports a lot of additional sensors and probes (including some home-brew stuff) that allow you to measure a lot of different things.Like I said, I paid less than $70 for the scope when I bought it. I already had the tablet, but if I had to buy one I could find a new one for less than $100. HScope has a free version, but the paid version adds a bunch of functionality. I bought a license as well as the automotive module. Both together set me back something like $30 or $40. By the time you buy an external battery, tablet case, and USB OTG adapter, you're looking at $200ish dollars. That is an excellent bargain for an oscilloscope that has this much diagnostic capability. For another $40, you can buy a Hantek 1008C and get 8 channels. Still a good bargain for automotive diagnostics.

one of my other favorite tools on the bench.

I like the build quality here; I feel like it will last and I don’t have any reservations about taking it into the field and maybe risking a bump or drop. It is a bit larger than I’d want ideally, but the cost is low and the value high.You’ll probably want your own probes, but that is pretty common.I tried both the manufacturers software and open source software (search “hantek github”). I prefer the open source app myself. It opens up some flexibility.

I was looking for a budget DSO for my hobby work which does not take much space on my bench. I was not expecting much in terms of accuracy but surprisingly it is fairly accurate and stable. The only thing which I didn't like is the software supplied from Hantek which looks like a collage project instead of a professional software. Also, it does not have support for Mac.I ended up buying "HScope" app for Android which really decent and far better than native software provided by Hantek and with my Tablet it makes a decent compact setup on my desk.I recommend this USB Oscilloscope for weekend users. It may take some time to get used to on screen button instead of physical button but it saves some space and money.

When fresh out of the box, this was a little laggy, buf for the price, it was a good deal. I liked it. Unfortunately, after about three weeks it failed completely. When plugging the device into my computers USB port, I got an error about the driver failing to load. After that, no computer recognizes that the device exists.
