Rigol HDO1000 and HDO4000 12bit oscilloscopes launched in China
Fungus:
The elephant in the room is that the DHO1000 is almost identical for a third of the price.
Martin72:
Yes and no.
After having the "big brother" for 2.5 weeks, I´ve made up my mind about the "little one".
They(rigol) have stripped the DHO1000 down to the common core of 12 bit and the 10 inch display.
Therefore, it can no longer be compared directly, rather with the competition from its own price range, the 2000X+ and the MSO5000.
And even then it doesn't look good for the 1000, it still has the advantage of the 12 bit resolution, but almost everything else is below the other two scopes.
But I would rather check it out live myself instead of just judging by the spec sheet.
Let's see if this works out, I would also want to borrow it, but Batronix doesn't have DHO1000... ::)
I´ll start a request elsewhere.

As mentioned before this can´t be the normal mode on the rigol.
Ultra and "Normal" are looking very similar, the blindtime between the packages are greater in the ultra mode.
Second part of my summary will following in the evening..

Hello I'm in need of some help :-//, Is the screen image formed by taking multiple pass, it does not appear at 2ns that a single write of 40 or 80 points is adequate to represent a visual image.
thanks

Will check it after work.

It is 120Mhz, but will measured between 119..121Mhz.
BUT: Rigol have a hardware (I guess) counter...
Following pics with 120Mhz and 1Vrms, look at the Vrms measure.

Hello, The noise floor of the Rigol, is elevated, then flattens out. Where as the Siglent is flat from start to stop frequency.
Why is this the case and what is the impact of the different in the time domain?
thanks gogo

Rigol has Hires mode ON. Hires mode is software filter that filters out high frequencies while interpolating more resolution..
In time domain it means a lower BW. In this case it behaves as 120 MHz BW scope.
