Rigol HDO1000 and HDO4000 12bit oscilloscopes launched in China

<< < (156/258) > >>

skander36:
On the HDO1K the probe stay on 10X after Autoset.
Maybe you should upgrade to 02.04 or active probe interface wait for confirmation (which would be a bug of course).

Martin72:
Thankyou for the hint, firmware is avaible on the rigol eu site, but must ask batronix before of course.

skander36:
I was able to downgrade to ver. 02.00 from Rigol site, but still the Autoset does not modify probe to 1X.
Maybe if you get permission to upgrade you will be able to isolate the problem.

For the HDO1K  users, on the chinese Rigol site they put the Fw. 02.04 on the DHO1K section along with the release notes and instructions. Release notes file does not tell anything about the improvements but intention is important  ;D
Also the firmware is the same for both lines (4K and 1K) as I suspected before. (DHO1000-DHO4000(ARM)Update)

Hi,

It´s not a bug, it´s a feature...
Today I´ve played a bit with the utility menu, there is a point called "Auto Config".
In this sub-menu you can choose if the channel coupling will be kept or not when activating the auto function... :P ;)
So this was solved.
I got the permission from batronix to change the firmware and so I did the upgrade.
Whatever this will do, without release information. ::)
After this I let it warm up (going out of the room, the fan noise is killing me...) and did a self cal.
Nice: It shows when it was the last time calibrated.
Self cal procedure takes appx 10min, that is fast.
Touchscreen response is good and like on my HD (and all other scopes I know) the rigol freezes the waveform shortly when moving.
I also got a look at the Acquire menu, the different modes.
Normal, average, peak, hires and ultra.
What I lke :
Hires mode you can select between 14 bit and 16 bit and the resulting bandwith will be displayed(depending on the memory depth) - Want to have this on my HD too...
BTW, memory depth:
Interesting the 1st: Default setting is NOT auto, it is 10k.
Interesting the 2nd: In averaging and hires mode, auto mode is not possible.
Interesting the last: in averaging mode the maximum memory depth is only 10M instead 250M  ???

The ultra mode is a little bit confusing as you can choose between several displaying modes (adjascent, overlay, waterfall, mosaic), but nothing will happen or weird things but not what you expect to see.
But I got a little idea what the reason could be and will check this tomorrow.

Does it change with the number of averages?
