There aren't a huge number of differences between the older C-series and the newer E/D-series, but I found it a bit odd that when they added an option to enable/disable sinx/x on the 1000E (which is a display function), that they put it in the Acquire menu instead. This is doubly odd, since to do so, they had to push the SamplingRate information out of the Acquire menu (where it properly belongs). At first I thought they had eliminated it, but it turns out they moved it into the Horizontal timebase Menu. Personally, like Agilent, I think the sampling rate is something that would be good to have on-screen all or most of the time. Especially since these scopes do NOT have an adjustable anti-aliasing filter in the front-end that automatically adapts when the sampling rate is reduced. It's all too easy to wind up being puzzled by alias artifacts when the sampling rate dropped lower than you realized (because it's a "hidden" parameter). - Mark |

From my experience, inexperience user can easily be fulled by aliasing if too slow sample rate is selected. In that case you can see the waveform, but you can not lock the trigger on it. So, if you can't lock the trigger, check the horizontal timebase setting ;) |

I've a DS1052E and I'd like to try the much talked about modification to the DS1102E. As the scope I have is 12 moths old, I asked Rigol about later firmware and I received an update via email. From a scan of the firmware file, the version appears to be 00.02.02.02.00. Before I go ahead and update the firmware and find that the mod no longer works, is there a way to dump the existing firmware or is there an older version I can get from somewhere/someone that I can restore so to make the 1102E mod? The version of firmware currently installed is 00.02.01 SP1 |
| Simon:
rumor has it you can convert on your current firmware and then upgrade and the mod will remain but don't quote me on it |

tumutbound: On the much discussed RCGroups thread, you will find the old firmware posted by Mark_O. I can't remember what page it was in, but it was discussed and linked in one of the last several pages. Simon: Of course if the only difference is the serial/model the updated firmware will work fine, otherwise they'd be bricking all of their legitimate DS1102E machines! EDIT: Old Firmware: 02.02.02 - I say old because I hear rumors that it's been updated to stop the DS1102E conversion |
