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.


Martin72:
Finally the siglent HD with 120Mhz 1Vrms signal..
The counter shows 120Mhz, the measurement 119.7, note the difference in the amplitude between rigol and siglent.
828mVrms to 961mVrms.
Second pic shows the FFt of the signal, the third the same but with ERES 3.0.
But it´s only for showing, note the measured amplitude of only 40mVrms.
Bandwith drops down to appx 12Mhz when ERES with +3 Bits is active.
(Note: Measures are taken with auto memory, when switching to fixed memory, ERES will be "deactivated" (switched to normal mode) )

Martin72:
The last days are dawning, where I can still test the Rigol, actually it is only next weekend and at the latest on the following Wednesday I want to send it back.
I will still perform my tests as already described, otherwise possibly still fulfill wishes.
Who has wishes, may communicate them.
In general, I am somewhat surprised that there is probably no greater interest in the HDO4000.
One must not forget, the HDO1000 is almost identical in construction, except for the missing second chip and less memory.
I'm just saying... ;)

Yep. The HDO1000 is the most interesting one.

It's all very well comparing the expensive model with a fancy Siglent but the fact is HDO1000 will be identical for most usage cases and it's a third of the price.

The fact that not many people are posting requests doesn't mean there's no interest. You're the expert, and you're the one who's got the hardware.

I'm more interested in how it is in daily use than the extreme edge cases that most people seem so obsessed with.

What does it do best?
What does it do worst?
What stands out?
What are the quirks?

How many thumbs up does it get?

Comparing 2 different classes of instrument here but later this year there will an opportunity to compare two 1000 series HD scopes.  :-X
