My keys were successfully applied using Ultra Sigma in Win7 64-bit, sounds like you had an issue with either drivers or the Ultra Sigma install. Well done getting it done anyway. :) |

That's what I first thought because I know that many people have successfully used W7 64-bit. But others didn't. In my case Ultra Sigma was able to communicate with the DOS and has read out the keys correctly with the *IDN? command. This worked for both 32- and 64-bit without problems. The :SYSTem:OPTion:INSTall command only worked on 32-bit for me. I don't know whether this is due to a driver problem but I do think that this is some kind of a communication problem that arises under not yet known circumstances. |

Hi *, I got an DS1074Z-S, but non of the generated keys worked for me. :-\ Unfortunately Rigol added a 12h timer when several wrong keys have been entered. :( I then ripped up the case and read out the W25X40B flash, tried another wrong key and re-read the flash again to find out where the 12h timer is located. It seems to be a 32bit timer at location 0x78007. The trail keys start at 0x78027. Removing them from flash and reentering would give another trail period, I think... Maybe someone out there has some interest and knowledge on hacking this? Greets, sethur |

Do I understand it properly that if DS 2072 A or MSO 2072 A has a hardware version 2.2 it is not possible to downgrade using an USB stick ? (and it works only for HW revision 2.0 ? ) Is the only working way opening the scope and dumping a memory with some JTAG tool as described in this forum ? |
