HANMATEK Handheld Digital Oscilloscope 100MHz Bandwidth 2-Channel HO102 3.5"TFT Mini, 2-in-1 Oscilloscope and Multimeter, Backlit Screen, Auto-Calibration Function, Memory Function

I have waited to review this. I'll firstly address the battery issue. Mine's been absolutely fine. I've had it for ten months and it's been idle for the last six. Just fired it up and it's showing about 90% full, still charges and everything. I say that because other reviewers have had issues with battery life.I think if you need a scope, this is a great place to start.I purchased the 50Mhz with generator.The broad specs on this are very acceptable for general use, 50Mhz will do most things, the 125MSa/s sample rate is good enough for my use. And the frequency generator is an incredibly useful feature. Not to mention the multimeter, very handy.If you don't own a scope, and you're curious. I would highly recommend the one I bought. I like the frequency generator for fault finding. I've mainly used this on vintage guitar amps. But I have also used it to diagnose injector signal issues in cars. Obviously just two channels, so you can only compare two cylinders at a time.I have a four channel bench top oscilloscope, sampling at the standard 1GSa/s, but I haven't had cause to use it since getting this. It's so portable, does basic DMM functions too and is just good enough for most things I need. I guess my use is diagnostics and fault finding.Fantastic value for money. If you're on the fence, I would recommend you just go for it. Wish we had kit like this fifteen years ago!

After messing up the language settings (reverted back to Chinese!) and getting them back to English (don't ask me how!) I managed to start using this Oscilloscope/Meter. Comes in a soft bag with all the required leads and a comprehensive manual. Buttons are soft rubber but very tactile and firm in their operation, the screen is clear and the brightness is adjustable. There are more settings to change than you could shake a stick at so I am not going to go into a full technical review here, suffice to say this is a good, quality, robust oscilloscope/Meter which is excellent value for money. I am looking forward to making full use of this in my job and hobbies.

Very good quality, much easier to carry out on a field visit than all the other kit you'd have to put in your rucksack to do what this can do all in one. Docked a star because if you're NOT on a field visit and are at home instead, a bigger desktop scope is much easier to use, with all the handy rotary controls etc - there's nothing they can do that you can't do with this Hanmatek (well, I do have one with an 8-line logic analyser and protocol sniffer, which can intercept UART serial ports, I2C, SPI etc and this can't do that, but is a feature only of interest in digital electronics anyway), just the fewer controls here make doing everything via the d-pad a faff. But it CAN do them, and is a perfectly good scope, just twiddling a dial on a device with a much bigger screen is so much easier than incessant menus. Image shows just the sig gen function from the Hanmatek below being read by an xminilab tiny single board scope above, even more awkward to use with just four buttons, but ironically has the most functionality of the three scopes I have, despite the least ease-of-use.

I do the occasional electronics project at home, and I own a nice Fluke multimeter, but every now and then, an oscilloscope would come in handy. I don't really have the space for a full-size desk scope, so when I saw this little box of tricks, I thought I'd give it a try.It's great! All the functionality of a basic 2-channel digital 'scope - cursors, measurements, adjustable triggering, XY mode - in a box the size of a Fluke, with a decent signal generator and an acceptable multimeter as well. The signal generator will do the usual sines, sawtooths, square and pulses, along with a few other more exotic waveforms. The meter is basic, but has all the functions and ranges you would want for most electronics work.The kit is pretty comprehensive, too - in addition to the meter, you get a carry case, USB cable and UK power adapter, two scope probes, a pair of meter probes and an output cable for the signal generator. The manual is a bit sparse and not that well written - if you already know how to use a scope, you'll be fine, but I wouldn't recommend the manual to a beginner. (If you already know how to use a scope, a meter and a sig gen, you won't need the manual anyway - the controls are all pretty logical.) It all feels of decent enough quality - it's not a Fluke ScopeMeter, but then it's less than a tenth of the price!It is powered by a rechargeable (via USB-C) battery, which is good for 4-6 hours.Cracking bit of kit, and fantastic value for money.
