http://www.box.net/shared/et7ztaxauf (this is official (old 02.02.SP2) upgrade package from Rigol to DS1000D and DS1000E model.) here is whole package. STOP: Read first upgrade manual inside this package, even if you think you know all things. (Important: Do NOT use D upgrade to E model!!! ) (If you have example DS1052E, move alone only DS1000EUpdate.RGL file to empty USB memory root. (USB memory need be FAT32 format)) Disclaimer: Only Rigol can tell you if you can upgrade or downgrade your individual machine to some FW version. If it works in one machine or ten machines it do NOT proof that it works with you machine. Some machines now, before, or future may be incompatible with some FW versions! So if someone upgrade or downgrade his scope without asking compatability he take just his own risk and he is just responsible alone if there is some bad effects or in worst case whole scope is just like garbage. (look example member "shafri" case. But this is becouse he maybe do many errors aftter errors and finalize whole error queue with wrong FW)! Rigol Upgrade note: 6. Before the upgrade, please contact RIGOL Technical and Support Department to confirm whether the current firmware version can be upgraded to the target version or not. ©Copyright RIGOL Technologies, |

from what i can remember... the problem occured before i upgraded to D version... while playing around with Serial Command. + E and D version are binari'ly 80% similar in content, maybe its just some data or splash screen bitmap at the end that makes them different... who knows? and when i reverted back to E version, the problem still remains ??? OK... if you people need an advice? just dont upgrade your rigol whatsoever, just use it as is out of rigol factory... unless... during your project development... u are hit by 100MHz barrier... and after that, just prepare to whatever come out of your modified rigol. version 1 or version 2? whether u need an upgrade? just ask yourself whether your rigol satisfiy you so far, or at least works as it should be. if the answer is yes... then dont give a damn on the latest firmware. sometime latest firmware will not do any good... just as ver 02.04 proved it. most people (including me), will be very happy when they switch on their rigol and showing ver: "the latest hunky funky" SP4, and be able to go down to 2ns timescale, but practically... it is very small/seldom use or nothing at all or even worst! |

anyway... if someone really generous enough and care to answer some of my curiosity here: other than EEPROM data... is it possible to corrupt/modify the software inside the CPLD/FPGA? are they meant to be changed in circuit? or is it a "software" inside? or something else "digital" or "hardware" thing inside? is it possible to corrupt/modify the bootloader inside the BlackFin? |

I hope some day we find enough knowledge about possible factory calibration procedure. If there is any, it may solve you problem. (I can still believe (hope) your scope can get its functinality back without opening case and hang around main board.) There may be some method how factory or repair sevice can load some important parameters to scope (I do not believe that normal user selfcal can do all this). Maybe there is "hidden" service calibration what can develop all needed parameters. It is not only how to start this possible service/cal routine but also of course need know what kind of signals it need for calibration. (of course it is also possible that there is not this kind of routine what is very common in professional equipments.) --------------------------- There is also one mysterious command. :SYSSERVICE ON (Do NOT try) |

Correct me if I'm wrong, but the only known problem caused by firmware upgrade was on shafri's scope, because he messed up with the D series file. So what's so dramatic about downgrading one's scope to perform the hack? There are several reasons why 100 MHz BW is better : - Even a slower signal often has > 100 MHz harmonics, thus it's representation will be more accurate on a 100 MHz scope. - It's very frustrating to have 100 MHz hardware with software restrictions... |
