Loto USB/PC Oscilloscope OSC2002L, Sampling 1G S/s, BW 50M Hz, 2-Channel ||Oscilloscope+Logic Analyzer || 8~13 bit Vertical Resolution || Protocols Decoding, FFT, Digital FIR Filter || Extension DIY

The media could not be loaded. What a neat little tool. Mike at Loto even upgraded mine to the X version since they didnt offer it on Amazon (X version includes signal gen module so you can do things like Bode plots of filters or amplifiers with it in an automated way).Super software (despite a few bugs and a couple of things could be improved as with any software). It is remarkable that the software came out of China (and it does - they do update their sw every few months). This has more finesse than most software out of the west - the rest of China and the world really could learn a thing or two when it comes to actually caring about your products like Loto does.Their hardware is slick and well built as well - very simple but stylish.I made a very short video for Amazon - but I cant say much in the 2 or so minutes they allot you here. I have made many VERY LONG videos about their product (and how it compares with some others on occasion) which I plan to publish on a new YT channel soon.This version of their product is the 200MSPS version and they get creative with its use with the various options. They have options like combine channel B w/ channel A to double BW of A. Most scopes do things like this automatically if you turn off other channels, but that can suddenly cause your main channel to 'change' - the Loto way is better since you have direct control as to IF your bandwidth changes or not - you may just be turning channel B off to hide it for a while).You have other options like setting modes between sinx/x or linear, Peak Detect (raw unaveraged at all frequencies), Normal (averaged a bit at lower frequencies and High-Res which gives you nicer looking and less noise on signal due to higher averaging levels at sub 100/200 MSPS sample rates (sampling rates are always in upper right scorner of scope screen).Also, they have MANY (about 100) videos on their YouTube channel (search LAO LV on YouTube) and their manual at 188 pages if well written, not typical for Chinese manuals. I wish it had more info in it on many details - but they have many videos. Only bad thing is most of their videos are in Chinese and only a few seem to even have English subtitles - they need to hire a technical translator or have someone dub their videos for other languages. But you can still learn a lot from them.A nice feature that some may like is while this is a USB device and is powered from usb 2.0 slot, it has an external power jack so it can presumably be externally powered if you wish. They supposedly have a model of their scope with WiFi or Bluetooth for a phone - so this would be good if you prefer to do things on a phone or tablet.Noteworthy is the PC cache capabilities (which get in the way sometimes - and it doesnt cache if you uncheck the checkbox on this). This can be set to as many as 500 frames of captured scope/logic analyser date which you can use your mouse to scroll through with the wheel so identify things that look odd.If you search Loto-ins (or Or use lotoins dot com) you can find their website and download their manuals and latest software from their Google Drive and play with it. The software has no 'demo' mode but you can still start and run it and look around even if you dont have a scope hooked up). The great thing is that their software is portable, so you dont even have to install it.... just click its .exe and it runs.Other features are cool like...- The 'Nail' feature which captures an image of the current waveform and tracks it with your waveforms vertical position on the display.- Decoder for decoding UART, I2C, SPI, etc- Signal generator - which can be set to sweep - fairly basic, but useful. it can do sine waves up to 13MHz,Triangle waves to 8MHz and square waves at less than 1MHz. It has external knobs to control amplitudeand offset voltage.- Several zoom methods- Spectrum analyzer, while basic is useful- Can add floating measurments in small windows on their Adva tab- PWM generator in lower part of screen by the 'waveform nail' buttons- Single capture mode to capture events that you manually capture with the 'Single Capture' button inlower right. This is associated with the 'Single Capture' tab thing above the scope window to see yourcaptures.- Has a Bode plotter that you use with signal generator- Has interesting statistical functions resembling datalogger- Has limited trigger modes but still useful. Supposedly this can be used with segmented storage modebut I havent quite figured that out yet (Chinese only video on it on their YT channel).- Can add annotations to your plot... but I do wish you could add text message type annotations to yourscreen like you can add measurement annotations.But all in all, this is a great little product. Even their sub $100 model is an excellent starter (though it is slower and lacks SOME of the features of this unit) if you are new to electronics - just add a cheap DMM from Amazon and you have a complete starter test lab. But this model is well worth it even for increased money given the lack of aliasing their scope seems to have - fantastic capability I didnt expect on any DSO let alone this product.

This is my go to bench scope. Had some issues but Mike helped me. I use it daily and it outperforms my Rigol. I have since bought the Differential module and the Current module. This is good for the hobbyist up to the serious pro. I really love it.

I don't give 5 stars often, but this one really deserves it in my books. The reason for me getting this scope is because it has the serial decoding feature, but after receiving it and playing with it for a little while, this product really deserves a 5 stars (as it already has 5 stars from other users). It took all but 5 minutes after unboxing to get signals of both channels A and B up on my computer screen. It did not require ANY installations; no drivers needed and the software can just be downloaded and uncompressed to any directory. The user interface is really easy to figure out; I did not have to refer to the manuals to get this thing up and going. The kit comes with two probes and a connector with several leads for logic analyze functionality. The UI is really easy to navigate as well. I particularly like the fact that the trigger level can be set by just dragging a line (trigger line) directly from the screen itself. It is well thought out, and functions really well. This is just perfect for what I need for small electronic projects. Price-wise, this is very competitive. It's not the least expensive product out there, but considering the features, ease of setup and ease of use, it's well worth the little extra cost, but definitely beat the heck out of the cost of those expensive bench-top scopes of the past. Time will tell if this product will last, but this is a solid recommendation from me at this point.
