Well, there's always a tradeoff. While the vastly smaller PNGs would write out to a memory stick a lot faster, it might take the CPU in the DSO longer to convert from BMP -> PNG than the time saved! Since high capacity USB sticks are so cheap now, it hasn't bothered me all that much to be dumping BMPs. I do agree though that RLE would be an obvious compression, which should be both easy to implement and fast to perform. Still, not as easy as simply dumping the raw bit-map, which gets the job done.
On my WaveRunner I can basically write snapshots in about any graphic format I want, so I do PNGs there. But that's really a PC in DSO clothing, so it has the horsepower to do that fairly effortlessly (along with a price-tag considerably higher than any of the Siglents).
I think we need to pick what we want to complain about, and for me this wouldn't be it. I'm not sure what other affordable scopes "from this day and age use JPEG or PNG for screendumps". Perhaps you could cite a few?
nctnico:
My new Gw Instek GDS2204E for example saves screendumps instantly (less than a second!) in PNG format. The largest screendump I can find is 32kB and mind you: the GDS2204E also has a 800x480 screen just like the SDS2000! Sending a few screendumps in an e-mail (which I do regulary) is much easier with images which are a tens of kB than having to send several MB or needing to convert the images first.

That is excellent. And it's not the only thing that Instek has done well on the 2000E series. Their post acquisition Search capability is unique in it's price class, and something the competition should wake up and emulate.
But I was wondering about how other existing DSOs handled this, and the relatively new GDS-2000E didn't answer that. I know from using them that both the Agilent X2000 and X3000 series (DSO's and MSO's) all support PNG format output. So I checked on the Rigol's, and was a bit surprised to find that the 1000Z and 2000A both support a broad range of screen image formats: “.png”, “.bmp8”, “.bmp24”, “.jpeg” or “.tiff” format!
So yes, your comment that the Siglent's handle only BMP format is a valid criticism, when compared against competitive units.

Absolutely no doubt about that. I'd never ship a BMP, but the extra step of running it through a converter is certainly a small hassle I could do without. And since even the cheapest Rigol can manage PNG (and much more), I think Siglent should seriously consider rectifying that. [ADDED: And even if the Crunch+Save wound up taking longer than the current RawSave, I think it would be worthwhile, simply from the convenience standpoint.]
But I still don't think it's a huge consideration.
F5D:
Any news of a new firmware version with bugfixes? Looking for a new scope and the SDS2000X hardware seems like a very good contender. However, would be nice to have the ERES and FFT working well, before making the decision. I believe the X-model uses the same firmware as the 2000?

Note quite the same, there are different versions for each of the 1000X, 2000X and 2000 series.
Re new 2000X FW, later today is what I've just been informed.
