Rigol HDO1000 and HDO4000 12bit oscilloscopes launched in China

Additional,
Siglent and rigol with their tables, judge for yourself what looks "better".
For me I like more the white background of the rigol table.
You also can see the advantage of having an averaging fft mode(siglent pic).
Fungus:
Controls aside: The noise floor on the Rigol looks to be more than 10dB lower so the peaks on the right hand side of this image stand out a lot more. The pastel color of the text is also a lot easier to read (in the screenshots at least).
Rigol:
Siglent:

And that means what ?

Fungus,
how much there is noise floor in FFT is very dependent on FFT settings. Namely bin width is very important, because, math..
One big problem with FFT on HDO1000/4000 as it is is that you cannot control some important parameters and it isn't clear what exact parameters is it using.. So direct comparison is moot.
Truth is that SDS2000X HD has few percent less noise than HDO4000 in general.
HDO4000 has a bit less noise at low frequencies and SDS2000X HD has less noise at higher frequencies..
But that is irrelevant because they are in the same ballpark.
But if software doesn't let you get the benefits, you still get suboptimal results.
For instance, on my SDS2000X HD i can easily get 15-20 dB less noise than what is shown for Rigol in Martin's images. Around -115 to -120 dB at same input sensitivity.. Just by choosing right parameters. And since Siglent did it right, I can do that repeatably and predictably.
Rigol made decent hardware. GUI looks nice. Now they should fix the actual scope software part, as i pertains to actual usage of the scope.
They started posting some fixes. Good. Hope for the best.

I appreciate the new Rigol UI. It's starting to look like a LeCroy. :-+
BUT the font they use is still reminiscent of the chinese way of dealing with the latin alphabet. They don't have much sensibility to choose the best charater font.
The font alone makes the UI feel somewhat cheap! Don't make me explain it better, it's in my guts.
