But I can tell you a scope is useful for looking at analog signals while a logic analyzer is useful for looking at digital signals. The scope records the actual voltage at each time sample while the logic analyzer just tells you if the voltage was above or below a given voltage. The scope typically has 2 or 4 inputs while a logic analyzer can have 8 or many more. 36 channels is not unusual. As someone pointed out logic analyzers often have serial protocol software while it is less common on scopes. Does any of this ring a bell for you?

It supposedly connects to various devices like a PC, an Android device, and an iPhone/iPad. I would be concerned about the stock software. Dedicated hardware might be best, but the one obvious benefit of using a PC for text and graphics applications is a relatively huge screen.

The issue has nothing to do with the PC connection. This is an oscilloscope made using an MCU chip... that's it, an MCU chip. Don't expect much performance because you won't see it. I bought the unit I have because I was considering a higher end unit at a higher price tag. Now that I know they put so little effort into the software and support I won't be buying anything with their name on it. There are competing products that actually work.

A scope with a display and control panel would be as large as a PC. I would like to be able to carry a scope in my PC bag.

Another thread mentions the pocket sized DSO150 oscilloscope. Part of my job entails field service, so a DSO150 was ordered for my truck's tool kit, mostly because the price is right. It'll be interesting to see how handy the DSO150 proves to be on service calls.

I haven't been able to log voltages for X amount of time (a simple programmatic thing), but it does act like an oscilloscope. I can easily and clearly see the speed control signal sent to my drone's electronic speed controller (x4), and see that it is a pulse width modulated signal. You just click on "Autosetup", it puts the signal in plain view, then increase the throttle and watch what happens to the waveform and the duty cycle readout.
