I think I've heard good things about that scope, but I'd prefer to avoid a USB based scope.

I was attracted to it due to its price and it was enough for the arduino stuff I am doing. However I can't recommand these chinese handhelds. Got one of the DIY, tiny display and to switch settings with three buttons is a pain.

Unless you find someone here that has experience using this device I would be hesitant to take opinions from others as to whether this device might fit your needs.

For instance I own a Rigol MSO2102A, which more than meets my needs.  Some would say it is overkill, while some might think it isn't enough.  So It really comes down to what works for you!

So unless someone can advise you yea or nay because they have tried it, I'd say if it fits your budget then go ahead and give it a shot, then let us know your thoughts.  Who knows, your experience may benefit many other members of our forum.

I've got FNIRSI-5012H 2.4-inch Screen Digital Oscilloscope 500MS/s Sampling Rate 100MHz Analog Bandwidth Support Waveform Storage. It does exactly what they say it does, which is more than good enough for what I do.

It was worth it to me, but it really depends on what you want it for.

I say that someone built a logic analyzer out of a Pico to capture the data up to 125Mhz and display it on a Raspberry Pi 4.  It was being used for looking at the 800K signal for Neopixel controls being driven by another Pico using it's PIO feature.

I'll see if he's posts a how to.  This was a Discord conference call I was on about CircuitPython deep dive on the PIO feature of the Pico

If your code won't compile, have another glass of bourbon. Eventual the problem will be solved.

Here's the link that I found:

I had some TD points left on Amazon so I picked up a DSO150. I'm embarrassed to say I don't have a small enough screwdriver to calibrate the probe! It isn't a Phillips or a flat head, it needs a weird V shape. Odd.

Firstly I wanted to buy DSO-138 Digital Oscilloscope  but after some research I found that it is more for fun, than measurements.

This is how I ended up buying one similar like you: 1C15 Professional Digital Oscilloscope . Despite it has 500Mega points instead 1-2GigaPoints, and quite low bandwidth, and only one channel, I found it quite enough for me. It is used for PROs in automobile industry so I guess this means something. Also it's bestseller on the site.

I am a hobbyst so if it helps me measure something, it's more than enough. It was like Cristmas when it arrived. Now I searching for tutorials for using it.🤣
