I should talk more about the test leads, it seems that they are not sold with the

Let me start off by saying that, aside from the fact that it worked for less than six months, I actually like this little scope. That said, it lasted less than six months of extremely light use (used for a few minutes on about a half dozen occasions, battery kept charged in that time), and when I reached out to their customer service department, my message was ignored. Disappointing, to say the least. EDIT. After writing this review, FNRSI reached out, had me do some troubleshooting, and then sent me a replacement. I'm happy once again.

Good companion to low level software development. Check for pins toggling, rs232, i2s. Wish these had decode. Little desk space. Battery life good.

I don't know how ppl are using this scope in real life application because it lacks even a basic things- no trigger voltage is shown- no signal is shown at normal and single trigger modes- it froze several times during 1 hour of use- zoom mode is completely useless- storage depth is so small you can't even investigate a waveform- roll mode is not continuous, signal just goes from left to right side of the screen, and then starts overIt's better to add 200$ extra and get some real thing, this one is just a toy

So I've had this for a few months now. It's a lot of value for what you pay. You'll need to read the manual to learn how to use the interface properly, the buttons aren't entirely intuitive. They've had to bury some things in the menus, and go with dual purpose on some of them. It's the price you pay for the compact size.I really like that it has honest to goodness BNC connectors for the probes instead of micro connectors like a lot of other portable scopes often go with. It's a bit bigger for it, but It means I can connect it to stuff I already have.I think my only wish for it would be if it had a connector for an external trigger.

Please understand, it says 2 channel, but ch2 is fixed at 200mv. hardly a real 2 ch scope.Also the output of the signal generator is also fixed at something less than 1 volt PPK.Always remember it's not what features they show it's the ones they don't show

I have been looking at these since they came out and finally purchase one. I was very impressed with it size and ease of use. It truly is a great value. I use on my work bench and take it to the. airport's shop.I am very satisfied.
