@Bud: not working for me, only the 200MHz is working  |O

@Sparky: i tried 3 Laptop running Win 8.1 x64 and one Win7 32bit, no Change  :wtf:

Just had a DS2072A updated to 300MHz. FW 00.03.00.SP1, HW 2.0

Used Bildschirmkopie to dump data from the scope via a SCPI command
:SYST:UTIL:READ? 15441920,13262848
then goes rigup-0.4 to generate the keys
then again Bildschirmkopie to install a key
:SYSTem:OPTion:INSTall A_KEY_WITHOUT_DASHES

Bildschirmkopie : http://peter.dreisiebner.at/rigol-bildschirmkopie-lan/download.htm
rigup-0.4:  http://gotroot.ca/rigol/

I am not sure why bother changing the scope firmware via a USB stick risking to brick the device, unless it is because of other goodies that I am not aware of. If all you want is options and bandwidth, the above procedure is non-intrusive and safe.

Is there some trick in getting Bildschirmkopie to see the DS2072A?  I've tried the utility method but that didn't work..  (I think something to do with the fact that I cannot get it to reset on startup), but the utility sees it just fine...  I just get a length error message and cannot get past that point.

So I'm trying the Bildschirmkopie method...  It does not see the scope via LAN, (I pull up the IP on the DO and enter it into the search feature), nor does it see it on USB...

The one difference I note from others on here is that I have SW Version 00.03.01...

Frustrating.

Instead of starting a new topic I thought I would post here.

Just bought a DS2072 non A model. From Toploser (Topbloke more like  :-+)

I have read pages and pages and pages on hacks for this model, things have changed a few times over the time it's been out so have a few questions.

Firstly I want to reset it back to defaults, remove all hacks (300mhz is enabled)
Update firmware (Not sure which is the best version?)

And enable all the options/hacks, but can someone please tell me what the best options are to enable and does 300mhz work on the non A correctly?
Apart from the 1m/50k switch do we now know any different between the A and Non A from a hardware point of view?

Any advice with the above will be gratefully appreciated.

No, I just ran the program and it worked by either search on the LAN or manual entering the scope IP.

Do you have a DHCP server/router on your LAN? Make sure the scope gets a correct IP that belongs to your LAN subnet and the proper default gateway. Try to ping the scope's IP from your computer, if you cannot reach it by ping then programs will not find it on the LAN.

I did not try Bildschirmkopie in USB mode, in fact I have not ever connected my scope to USB. But I'd guess when you plug it in you could check in Device Manager (if you are on Windows) that it shows up there in the list of USB devices.

Let us know if any progress.

EDIT: make sure you trying to connect  using a single method, i.e. unplug the USB when trying by LAN, see if this helps.

Hi,
I used the following steps:
:SYST:UTIL:READ? 1,33554432
"Senden und Empfangen" button - the result is file with huge amount of data (32MB), but I was definetely succesful. Be patient, the read process is long (approx. 5 minutes) and during this time "Bildschirmkopie" seems to be non-working.
"Speichern" button ... save the file for rigup.
I hope everything is clear after that.
