Oscilloscope - 2 Channel Handheld Digital Oscilloscope Kit, 50MSa/s Sampling Rate, 10MHz Bandwidth, Trigger Function Auto/Nomal/Single, Portable Automotive Oscilloscope

Portable. Good battery life.

It came with two X10 probes with BNCs and one direct probe with alligator leads. The documentation is very sparse unless you read Chinese. Play with the unit for about 30 minutes though and you'll figure it out.Here's what I discovered.A long press of the MENU button brings up a screen that lets you choose between the dual trace scope mode, X/Y mode, and a single trace DC current history display. (those terminals on top are the current input, 6A max.)In Scope mode, the Left/Right buttons let you step though 18 different parameters. The selected item is highlighted and the +/- buttons change the values. The claimed bandwidth is 10mhz but another reviewer said the unit is usable to 15mhz which sold me.If you go to the Website pointed to in the docs you will see what looks like a full manual in Chinese and several blurry videos with Chinese narration. Scrolling to the bottom of all that yields three pages of English documentation. There I found the names of the two cursors that I could move around but didn't seem to do anything. They were the vertical and horizontal trigger pointers, something else to explore...Battery life is good and the unit feels substantial.All in all, this little scope seems well worth the price.

I'm sad that I had to return it. I really wanted a smart-phone sized oscilloscope that operates on battery power. I'm well versed in using oscilloscopes but I wasn't able to get it working properly. Went through all the menus, tried a bunch of things, but still no luck. Maybe there's a way to get it working properly but I was unsuccessful. The manual is woefully deficient.

seems to be an ok unit for my needs, which are just to check the AC phases of my generator.

Works fine, easy to use.

This is probably more a gimmick than anything else. Is it better than a multimeter, yes, probably for certain applications. But I wouldnt use this unless my existing scope was broken.Hard to setup, not very friendly.I remember in the good old days we made our own scope using the audio input on the sound card. Then we made our own scope SW in Windows. This scope is portable, but doesn't feel light years ahead of what we were able to do.

Too frustrating to operate as the non manual is useless

Quality: Decent build with solid BNC connectors and ports for TTL I/O and USB charging. Buttons are a little "squishy".Functionality: Most operational parameters are set using the menu button. Setup is not intuitive and takes a bit of time to become familiar with. To operate the oscilloscope in XY mode (for example, Lissajous patterns), it is necessary to set this mode immediately after startup and not through the menu.The oscilloscope was tested against a low-end signal generator that had been calibrated against a moderately high-end Fluke 117 multimeter. A variety of waveforms and frequencies are employed for these tests. See images for 10 Hz and 15 MHz sine wave input signal. Surprisingly, the oscilloscope frequency accuracy was well within specifications, even above the stated 10 MHz limit. The peak-to-peak measurements were not as accurate. The battery life was not tested, but was still going strong after an hour of testing.Considering the relatively low cost, flexibility and accuracy, this is a decent oscilloscope for the tinkerer, on a budget. Only complaint is the tiny display, but I guess that is what makes this a low cost oscilloscope.
