With the probe set to x1 the bandwidth drops to about 6MHz. It even says so in the manual. The one thing they did not lie about  :)

I want you to read this thread. Can I improve the generator like the owner of this thread?

I got the scope recently, needed something portable to find why my car did not want to run.

In my use case I found 2 areas lacking:

1)If you use a wide time band (ex. 100ms per division) it will miss a lot of data. Theoretically it could capture the data (with a supposed 1GSa/s) , but seems like the limitation is in the sample memory (supposedly 240 Kbit). When the trigger hits, the oscilloscope captures 30 time divisions. With one sample supposedly 8 bits, you get 30K samples over 30 divisions, so 1K samples per division. But I really doubt it's 1K samples per division, and I am a beginner with oscilloscopes so not sure if I have correct assumptions. So if you don't know what the frequency of the signal will be, you might miss some important details if you use too wide of a time division.

2) The trigger behavior seems odd. I used a Rigol DS5102CA before, and the trigger was intuitive. With the FNIRSI it seems odd and I didn't use it enough to say what is wrong, but it feels like it's not a good implementation.

What I chose to buy it:
In my area you can't find a good oscilloscope for a decent price. I needed a portable scope, and with all the drawbacks this one is the best option.

If I would be in the North America I would get the Rigol DHO802 for 330$ and not waste my money on the FNIRSI. But I am in eastern europe and the DHO802 is 415 euro, and I have to also add 20% customs VAT (and potentially shipping), so that makes it 500+ euro. So the 130 euro FNIRSI it is.

It's not something you can confidently use if you need it for serious/responsible work (at least that is my opinion), but for a lot of use cases it gets the job done.

Why didn't you buy the 1013D, it's actually a portable version of the 1014D.
