It definitely is possible, as I have just successfully demonstrated a 1M 32bit hardware FFT on a Zynq 7010. The bottleneck is DRAM bandwidth and in my case I can get up to 70 FFTs per second. I think up to 16M points should be easily doable on a Zynq 7010 which most of these scopes use.
Yes, I saw your thread and I am tempted to try it on my Pynq board
. The list of cool projects is getting longer and longer...
PS. Anyone who wants to buy any of my scopes is welcome to make me an offer
Well, if you can wait for me to finish my study and get a job first...
I am a rank beginner hobbyist so take this for what it is worth. I went with the 1104E-X because of slightly better specs (2 ADC's) and the fact that Siglent is still actively fixing/improving the software. To ME the $150 ish extra cost of the Siglent over the Rigol was not enough to sway me. I may well buy another scope in the next 5-10 years, but over that time span the cost difference is minimal, to ME. There were just not enough of the GW Instek's visibly in use for me to really consider them.
Thank you for voicing pretty much what I am thinking! Yes, there is a €150 difference between the two Siglent/GW Instek and the Rigol, but if one is a device I know I will regret spending my money on every time I use it and the other is one that also does the job just fine with a few quirks, then I'd really rather spend the additional money.
I love my Analog Discovery's, I bought the new model 2 years ago when I could not decide on a scope, the picked up one of the original versions on eBay for $50 because it was too cheap to pass up. The AD1 is 95% as good as the AD2, they only made a small power supply change to the hardware between versions, and the spiffy case
But if you had to choose between getting an Analog Discovery 2 now (plus maybe a hot air soldering station or something) and an oscilloscope in a couple of years, or getting an oscilloscope now, which would you choose? Of course we might have different requirements of it, but just in your situation?
This.
If it were just the controls, maybe. I'd really rather buy everything sequentially and get what I actually want to use than get multiple things at once and then not buy what I want.
If I had had the opportunity to try out the Rigol before ordering it, I wouldn't have ordered it. Looking around on the internet, it seems to be a personal thing whether the speed of the Rigol is something to get used to or something to get frustrated by. I tried. When it was here, I really, really wanted to not be so annoyed by it. But that only made the disappointment worse, so I returned it.
