My post is because I, thinking about to buy a Rigol DS1074Z, and my question is if the keygen fror DS2000 could be valid also for this DSO, or if there is someone who is working on it.

Thanks

Use one of the On-Line Keygenerator (you want to use it for DS1000z) at* > 
RigLol keygen: http://riglol.3owl.com
Canadian mirror: http://gotroot.ca/rigol/riglol/
UK mirror: http://rigol.avotronics.co.uk/mirrors/riglol/

Do NOT install 500uV Vertical Sensitivity, as it doesn't work properly (buggy*).  Therefore do NOT use 'DSBA' - 500uV Vertical, or 'DSFR' - all options.

1. Type in your unit's Serial Number.
2. Type in DSER* for all options without the 500µV. This Option may not be in the Keygen's list, but it will work!
3. Do NOT enter anything for 'Privatekey', it will be inserted automatically for you (based on the DS1000z).
4. Press [GENERATE], and record the resulting Option Code.
5. When you are done enter the Option Code manually in the DS1000z using a single string without using any 'dash' (-) using Rigol's Procedure for activating the Trial Options in the D1000z.  As I recall the procedure is available on Rigol's Web Site under DS1000z.

    Good Luck, and if you have questions please feel free to ask me.

And while you are at it ... take notes and write down times and stuff. If in fact Rigol did add some counter measures (unconfirmed hypothesis AFAIK), chances are fairly good that you still have a 100% usable instrument. As alank2 suggests, just leave it powered for a while to let it time out.

Success! I have now installed the 300MHz key generated by rigup 0.1 and all options are now listed as official.. I left the scope powered, but off, for some days and it now reacts to ":SYSTEM:OPT:INSTALL <key>" again..

It seems the timeout is somewhere between 2 and 4 days.. the trial keys still had minutes left, so it doesn't appear to be linked to those..

cheers everyone, and thanks for the great work..

BTO:
Just thought i would POST the fact that i've managed to upgrade my scope
DS2072A from 70Mhz - 300Mhz

if anyone needs help, let me know

In the FW there is this text: refused to install, please try again after 12 hours,
and also : interval to short, pls try again after 30 seconds.

so it seems there are some brute force restrictions build in.
