Wall-E:

--- Quote from: rob040 on October 10, 2017, 03:10:04 pm ---Today I've received a reply on my mail to Rigol asking for a release date of the new software. I was asking for that after reading this threat.
Reply came from Rigol EU, but not giving a date. I also referred to the long existing typo "Pluses" and the answer on that was that it was first time reported to Rigol only 5 weeks ago.  :-//
So, if there will be a new release, at least that should be solved... The rest will be a surprise.

Rigol told me that if they only get a couple of complaints its is generally ignored and not thought about as necessarily being a significant issue to be concerned with, or taken that seriously.  But when they receive multiple reports, say over  10, 25 and more on a new active product it is indeed taken seriously.  Right now most of the Rigol equipment is mature enough that it isn't a active design product, and as a result it takes a lot of complaints, possibly hundreds, to get anything changed in the firmware.  After all the software teams are off on to the next product designs.  That's not hard to understand for any progressive business organization with new designs in the works to enhance their product line.

So guys we need to get together and each chime in when a issue is found if we want to have any action taken.  Is this so unexpected.  We all need to do our share of bitching to get something done.  Don't just let it go because someone has submitted a technical support issue.

On the contrary, it is very hard to understand from a test & measurement company that claims:

"Uncompromised Performance… Unprecedented Value"

Well, you know what "value" means in marketing-speak, right? It's a euphemism for "cheap".  :P

But, seriously: Of course Rigol will have to triage, and will not fix all issues. Otherwise they would never get around to releasing further new products once they have to sustain a few existing products in the market.
Karel:
I want to add another bug. The DS1000Z series does not display the full vertical resolution, it clips it at 80%.
The 8-bit ADC produces 8-bit samples which have 2^8 = 256 possible values. Only 200 of them are visible on the display,
the rest is cut-off.
Downloading the waveform sample data will give you acces to the full vertical resolution.
Have a look at the screenshots, one is made internally in the scope and shows the clipped waveform.
By using DSRemote you can view the full dynamic range of the ADC. It's an increase of dynamic range of 25%!

I think you are mistaken (or I do not fully understand).
My guess is, that you have not yet figured out that you can set the division from coarse to fine. »coarse« jumps from 1V/div to 2V/div whereas »fine« lets you also select various zoom factors between 1 and 2 volts (or which ever range you are in).

Edit: In case you did not notice: The screen of the 1054Z gives you 8 vertical divisions while the emulated 1104Z screen shows 10 vertical divisions, hence can show the full waveform without clipping at 2V/div.
