The new method can also work with the DS2072A-S (with 2 channel function generator :scared:)? Has anyone tested on it? :-BROKE That you know.. there are codes that add functions to the signal generation? (I did a stupid question? :blah:) Thanks as always and lots of compliments! :clap: |

Guys, can someone tell me where to find stock firmware. Is it uploaded somewhere? I want to feel a bit safe before I flash to the modified version. I know about request page on rigol, but my scope already has latest version. I can't request firmware upgrade without a reason. My firmware version is 00.02.01.00.03 (DS2072A) |

Thanks! I searched a lot, but I guess there were no words like "stock, original, unmodified" And if someone points out the post where someone explains how to uninstall features I would be greatful. I see a lot of people mentioning some commands but I don't know how you specify what option to uninstall. I guess the commands are sent to via ultra sigma software. edit: because it's easy to mix the firmwares here is the sha1 of the original/stock for DS2072A (if I downloaded the correct one) ddf1d511823eaf31f1d05af2ba845543d97c6d3a DS2000Update.GEL |

One thing I've noticed on a DS2072A with all features unlocked (using the recent rigup license generator on zombie's 00.02.01.00.03 keydump firmware): Although the CAN decoder becomes available, it appears not to work correctly. Watching known good CAN traffic, the decoder attempts to decode, but gets things wrong (the ID, the data length, etc). Looking a bit closer, it appears to be neglecting to account for CAN stuff bits. I notice that Rigol doesn't offer the CAN decoder option for purchase for this scope series (as far as I can tell). This might be why- it's broken. Has anyone else actually tried out the CAN decoder? |
