FNIRSI DSO152 Oscilloscope - Portable Digital Oscilloscope Kit

produto em bom estado e funcionando normalmente, útil e satisfatório, não fiquei decepcionado. Não é profissional, mas funciona.

I have used this unit for a couple months now, and I absolutely love it. The features it has are well-chosen, and well-executed. (I can't speak to the battery life, as I've never let it run out completely.)Pros:*Onscreen display of Vmin, Vmax, Vavg, Vrms, Vp-p, Freq, Duty, Period. All the useful stuff that you use constantly. These are just already onscreen without having to configure anything, no fuss, no muss.*Accurate. Readings agree with my other (reliable) meters/scopes.*No menus. Very simple interface. Cycle through the settings with the wheel, adjust setting with the arrows. Nothing to it.*One-handed (right) operation.*Easy-to-read display. Big enough to see what's happening, small enough to fit in your pocket.*Decent 1:1 / 10:1 probe included. Better than the one I received with a Hantek scope. Kit also includes a set of alligator clips, and a USB-C cable for charging.*Full-size BNC adapter, so you can use any standard oscilloscope probe with this scope (!!!). Not having to deal with proprietary probes is a huge deal to me.*Fairly low noise. Displayed waveform is clean without a bunch of chaff.*200 kHz range is well-chosen, and is more than enough for appliance or vehicle diagnostics.*Full-size dedicated Run/Stop button to freeze the frame.*So, so, so portable. Your phone is bigger than this. Absolutely wonderful when you're upside down under a car dash. You can even hold the probe and the scope in the same hand.*Cute little pop-out stand keeps the unit at the perfect angle on a bench.Cons:None, really.Some might gripe that it doesn't have the capabilities of their $5000 4-channel main-battleship scope at home. Well of course not; what did you expect??? This is a 200 kHz single-channel unit that is intended to be a highly-portable, battery-powered, easy-to-use, on-the-go pocket oscilloscope. As such, the designers really hit the nail on the head. Very nice unit, and easily my favorite tool purchase this year.

Good for starting and learning about frequency waves on vehicles without spending a lot. The only minuses are the voltage rangetopping at 100v and the time floor at milliseconds and not microseconds, but that you can get later with a more advanced model of this same provider.The controls are intuitive, the screen is easy to read, the construction is light but solid and the battery lasts long, what else can one ask for at that pricepoint?

I found this tool a bit difficult to understand at first but after a little bit of youtubing how to use a oscilloscope, I found it to be quite portable and easy to use. If you do use it in a professional or a hobby setting, I have found the leads to be way too short and it lacks a magnetic back to stick on a hood or a fender. Otherwise fantastic and would buy again

Mechanics, best friend.Put it in your pocket and forget about tell you need it..Easy to hook up. And use .Something would happen to it. I definitely know I mechanic would miss having it And buy another one. That' show handy.,They are very good product for the very little money unbelievable. You would pay more just for the attachments if bought separately.
