Either he is too stupid to put all scopes to the same sampling settings, or the deliberately wants to make the rigol look bad.

As you seem to realise that this is off topic here, why do you still post?

As example: When pressing the source button it switches to a separate management (as a second instrument) or is a more integrated management?

On the DS1074Z-S it's a separate "device" inside the unit.  I can generate a signal via one set of menus and view it normally, and all DSO functions work as if the signal were coming from an external generator.

Pushing the "source" button on the front panel brings up menus for configuring the function generator and turning channel 1 & 2 on and off, etc.  Pushing CH1 button puts it back in scope mode and it's like two devices under one UI.

@neslekkim thanks. I didn't find it first time, but thanks your link I found it:
@tiagobaracho You can uninstall all options by the command:

:SYSTem:OPTion:UNINSTall

And for completeness - to send commands to the scope you can run ultra sigma software and connect using LAN or USB. Then right click ion the device and choose SCPI panel.

To install only the 300Mhz key use:
:SYSTem:OPTion:INSTall XXXXXXXXXXXXXXXXXXXXXXXXXXX

Where XXXXXXXXXXXXXXXXXXXXXXXXXXX is the upgrade key without dashes.

Or you can install the key again using the install menu on the device

That you know.. updating a DS2000A-S with the patched FW there is a risk of losing access to the signal generator?

I still have this same question.  I have both scopes in the cart and I'm waiting to pull the trigger on one, but I hate to gamble either way.  I cannot find anyone on the forum that has performed the upgrade on a 2072A-S version.  There is a thread and I've asked, but haven't gotten a solid confirm.  I thought I read that the -S model incorporates additional hardware (daughter board?), it would seem that the SG is separate from the rest of the scope as it has its own output and buttons, but OTOH I think you have to use other dedicated buttons/dials for additional settings, so it could have a different FW.  Flashing to a non -S version could wipe out the ability to select/use the SG.  It would be a real bummer to not get the option (as this is the way I am leaning) because I would really like to have it.... not so much of a bummer though if I were forced to decide between the SG (extra $350) and the patch.  This site and all the work of the super contributors are what put me over the edge for purchasing this brand/model. 

I guess overall 350 is a pretty steep price to have the signal generator integrated.  One can get a really nice SG for a few dollars more... I was just hoping to save a little money and get a better unit later.  Perhaps I have answered my own question as to what to do!
