HANMATEK 2000mhz Bandwidth DOS1202 Digital Oscilloscope with 2 Channels and Screen 7 inch / 18 cm, TFT-LCD Display, Portable Professional Oscilloscope Kit with 1000 MS/s Sampling Rate

My old O'scope is a Hameg 20 MHz dual-trace I bought in (then West) Germany in 1982 for about $2,000. It's heavy, has a tiny CRT and dual-trace, but I've lugged this thing around for 42 years and now it's almost obsolete, but still works, and it can be plugged-in to a variety of power sources!The HANMATEK 110mhz DOS1102 only weighs a few pounds and exceeds my old scope in everything else. After it arrived an hour ago I looked through the handbook trying to acquaint myself with the parts and controls, but the hardest part was figuring out HOW TO TURN IT ON. The technical support guy I contacted gave me an URL and I watched a short promotional video that showed WHERE the power-plug went, which, if you don't know, is almost invisible on the left side. Not what I thought at all with 2 USB plugs (which are only for signals to a computer.)What's missing in the information on the Amazon page and the handbook is the most simple thing you just might want to know, like "How to turn it on!" Amazon needs to have that video, not the other one that shows you almost nothing...Once I found the small plug-in and pushed the on/off button, it popped on instantly with a beautiful color screen showing glorious fine detail. Oh, that's NICE! The Oscilloscope techniques will come around without much effort. I actually went to school at Lowry AFB in Denver to learn how to repair and calibrate these things and other delicate instruments. (At least instruments like a Hameg 20 MHz.) Now I'm not so sure because everything is on IC's and if something goes wrong it might just be cheaper to buy a new one (instead of trying to de-solder a chip from the board and replace it with the same model number chip, IF you can even find it...) The good thing about IC's is they use tiny voltages and currents and have greatly extended life compared to components like tubes, resistors, and capacitors. For now, I have a new, very compact and lightweight scope!

I always want a scope for field use, something that I can pack in a suitcase and has an input bandwidth that I can see most of the signals on my boards. This scope is very small (and light!) yet it has an input bandwidth of 110 MHz, a large screen, with all the basic functions that a digital scope should have, and it's so economical I almost thought that I bought a DMM. It's good for field use, and it's so easy to move from test to test in a lab setting. The bandwidth covers most of my needs. I even use it on signals that have a rise time below 20 ns. Yes, I know I fold in the rise time a little bit that from the scope, but just checking if I have a signal a not, that's good enough. If I really need to have a precision measurement, I roll out my heavy scope with 500 MHz to 1 GHz bandwidth (but I also paid a hell lot more for those scopes and I do not really want to use them unless I have to). Another great use of this scope is in undergraduate research or senior design projects. Breaking things is a natural process of learning and believe me, students are very good at that (the breaking part, not always the learning part that should follow). I work with several students a year on such projects, I now have a scope for them, and I will ask them to try out all the functions, including the remote connection and DAQ part, that I find very useful but have no time to use myself.

Been using mine for over a year--still works! Amazed at the functionality for this price. Even the internal frequency counter seems to be good to better than 1%. Only downside is a small baseline HF ripple noise--seems to be either sampling or insufficient filtering somewhere. Not the switching power supply--tried quieting this to no avail. As usual, manual is sketchy, but hardly undecodable. Price actually went down over the past year!

Long time user of high end Tek, Philips etc. I find this scope very capable and more than I need for my hobby. I still have my Tektronics scope. If my office gets cold I will turn it on.

So like a normal person I find the Hanmatek.cn/en site and eventually find the software download page. Unfortunately no one could be bothered to post a user manual pdf there. Run the install and it installs but can't find the device driver. Run the install and reinstall packages I find, but drive not detected. I worked as a Microsoft tech back in the day so I kind of know how to install drivers. Sadly, there is no driver in the install package, which makes this oscilloscope a doorstop if you planned on using it with the computer interface. Also there are no firmware updates on the site, which it is supposed to support. Minor grievances is that it uses a usb charger but the device itself has a barrel connector. Please it should be a usb connector on the device. Second grievance is it uses a 20 year old style usb printer cable. Should use a usb 2.0 standard cable, but if Hanmatek is listening lets get both connectors to usb-c. Wifi and/or bluetooth would be nice as well as linux and mac support - and adding the hardware for this would be like $5.00. Probably will return.

I purchased this for a small one time only learning activity I was doing for others. This was easy to setup because of the lack of options. This is as simple as it gets. I have used much better ones in labs, but for the cost this performed its intended function well.

Im new to these osillyscopes, lol, but i think when nothing is pĺugged in it is supposed to be a clean lineI have one clean line the other 3 are wider and fùzzy. It's osillyscopingbwith nothing plug in. I followed all the directions but can't get it to show me the engine coil signal wire calling to fire, just a bunch of noise. Don't have to plugged in and hooked up either. I love a challenge so im going to try and figure out its problem. It was a something play with, now i have sonethin̈g to try and fixI don't consider it a good buy if you need a working oscilloscope

Great working scope and meets bandwidth specs. easy to use with short learning curve.
