Well no doubt this has been in Siglent's pipeline for some time. They didn't just start working on it after Rigol released the DHO800/900 series. Rigol just beat them to market, and as you point out, Siglent seems more likely to release a more finished product rather than rush things just to get to market first. For all we know they've been working on it as long or longer than Rigol was.

That said, being 2nd to market brings some advantages -- you get to see what the market response was to the 1st, and to focus on filling any glaring gaps the competitor either didn't consider or thought were unimportant. So you can distinguish your release from theirs and take market share. This healthy competition creates an oscillation effect that motivates each to improve their designs, which is good for all of us. The entry/hobbyist market is much more constrained by margins than the high cost pro market, so their profit motivator is getting and maintaining volume. They can't afford to sit around.

I hope it doesn't happen, but at some point Siglent may decide the economics just don't justify the cutthroat hobbyist market and may forfeit the low end to Rigol, Hantek, FNIRSI, et al, while shifting more towards the pro or "A" brand market where they can demand higher prices. They already seem to have a considerably higher premium product line than Rgol does. I do hope they stay competitive in the hobbyist/maker space though, as I really like their products and again, I'd expect Rigol to feel more pressure from Siglent than they do the cheaper Chinese brands mentioned. Rigol might get lazy if all they have to "be better than" is Hantek or FNIRSI.

It would be very bad news if either Siglent of Rigol won the economic race grounding the other.

Update:

@rf-loop I think this time we are getting the true result, and it also the same as Siglent marketing "under 70uV noise at full bandwidth" :-+

Also I noticed the CH3 noise is much smaller than others

@tv84: The SCPI command return a board version, see in the picture :)

Yes. Thank you.

CH3 noise is naturally more low than others because CH3 is set for 20MHz BW when others have full BW
When there is wide bandwidth random noise and we then reduce bandwidth... if we half BW noise drops 3dB but in practice not perfectly because there in oscilloscope is not only "ideal" flat white noise.... there is more things what affect here.

That shows that the scope uses the public keygen.  ;)
