I bought one Rigol DS2072A
It shows Software version 00.02.00 and Hardware version 2.0... Is that possible to use the 200 mhz and high memory settings ?
I have been reading a lot of pages in this thread but i could not find....
Thanks

You can use either my first firmware patch (https://mega.co.nz/#!FFk10SCY!UuWPXyqZwmca00pa2clOth1ryh1Z-AAgJg2yibfoUw0) with old keygen (riglol.3owl.com) or my newest patch from the post above with the new tirulerbach's keygen (if he decides to publish it).

zombie28 !great!
What is the difference between the first firmware patch and the newest patch?
Just don't need to manually enter the keygen on the oscilloscope?

As you seem to have missed some of the last posts, let me provide you with a short update: The old patch allows to use the keys from the old keygen, the newest patch will spit out needed key information to generate keys with the new keygen.

Hi tiagobaracho,

you wrote:
worked like a charm!!!
Now it shows all official Version and only one line with 300m bandwidth

I cant belive it has the same hardware as the 2500 usd with 300mhz... and i paid only 788 USD and you guys from this thread made it happen !
Thanks!
So.. if we need warranty, all need to do is to uninstall the serial and update to stock firmware right ?
And probably those options will work even on future firmware updates ? since its a serial number ?( maybe isnt worthy updating..... the team is winning... why risk , right ?)

My question:

does your DS 2302A work stable as there it is mentioned in this forum not to be. So what is actually right?

@at2: I installed the same 300Mhz BW option and then reverted the firmware back to the unlatched version and the scope (with my minimal use) has seemed stable enough. I will continue to do more testing.

As for the DS2072A being the same HW, please remember that no one with a DS2302A (to my knowledge) has posted test results on performance, so there is nothing to compare against just yet.

@ispromnut
Thank you for your fast reply.
You are right.Testing this 300MHz mode may be the answer.
