The worst that could happen is scope might get frozen - but it's still under warranty (and they would never know what happened). But since the DSO has a bootloader (and since HW v.2 owners have upgraded and downgraded) - and NO ONE has ever managed to brick one of these DSOs (AFAIK) - it's highly unlikely that would happen, so a more likely worst-case scenario is that it just won't downgrade - or the keygen won't work even when downgraded. |

Even the number of guys around here who hacked their scope and still following this thread seems to be relatively small. I could do some more signal-generator measurements on my 2.0 HW DS2072 (look 10 pages back), but it seems that my generator drops the output amplitude significantly with frequency (compared to 500MHz scope), so it doesn't look that reliable at the moment. Someone with a known-good generator is needed, maybe we can compare directly. I really don't want to publish these cutoff-freqency measurements at that moment, although it looked like 2.0 HW brings way more that the 315MHz at my scope. Plus, we still need high-res pictures of DS2072 2.0 HW input stages for last proof if it is the same as DS2072A. Maybe I will do this in some time, the thing with the warranty seal seems to be feasible. |

I think I can help out. I bought a 2072A a couple of weeks ago and thanks to cybernet's JTAG pinout :-+ , I currently have it open on my bench with urjtag connected to the BF256 :D I should have a memory dump pretty soon... |
| NikWing:
that's great :) I forgot the jtag at work and it also seems like it's not as easy to read out (as I thought ... need of linux, adapter ...) |

I'll try once there is a firmware dump. |
