With these units what I have before all goes ok. I have not yet find solution with these new. If I try as before, display go sometimes "black" and only button what make anything is power ON/OFF. After this scope continues as DS1052E (serial number it (sometimes) keep as I type it, but it return to 1052). Some times there is only white random scratch over model number row from left to right over display.) One time it was totally difficult to return so that system display was ok. --- End quote --- I saw the exact same thing happen on my unit at first. It changed the serial number ok, but the model number reverted back to the old 1052E. I think it had something to do with me accidentally pressing an extra serial key between entering the info in. But when I did it exactly as shown in my video it worked fine several times. So it does seem a bit "touchy" with the command sequence used. Dave. |

Hey Dave, thanks for giving credit and breaking it down for everyone in your video. I actually brought up this hack in a job interview recently to prove I understood measurement instruments and it raised a few eyebrows. Rigol might indeed change their firmware.. In any case, the hardware hack is pretty simple too, so I'd like to re-iterate that in the case that they do fix the software mod then the hardware hack will still be valid, I doubt they'll totally re-design that aspect of the scope or ditch their whole business model of selling two models.. it just wouldn't make sense. I think that mostly anybody is capable of replacing the disabled bandwidth limit inside the oscilloscope with their own external circuit. I bet they're selling the crap out of them now, so who knows if they care about this at all really! Everybody knows that serious (commercial) customers won't be using hacked scopes professionally, so that just leaves a huge spike in sales to the hobbyist market. |

So in that sense, this will always be available. However, disassembling, modding, and reassembling a unit, while not inordinately difficult, is much more work than sending 2 SCPI commands. And therefore, fewer people will be inclined to do so as a result. And secondly, the hardware hack gets you the extra bandwidth performance, but doesn't convert the unit into a full 1102E, like the software hack does (timebase down to 2 nS, etc.). So the software hack is preferable in that sense too. - Mark |

A little birdie has told me that Rigol have already fixed the firmware to stop the hack, from at least the latest version 2.04, and possibly before that. It does not let you change the model number, but you can still change the serial number. But apparently if you hack it with the old version and do the update to the new firmware, the mod sticks! And apparently you can downgrade firmware as well, so it's should still easy to apply the mod to new scopes. I now have the latest version 2.04 file so will have to give this a go. Dave. |
