I will receive mine in 2-3 days. I will inform here if the optical encoders have the same issue or not. |

It seems that the BF promotion was extended 'till the end of the year, but not for all of them. 1072 was removed from the list and 1102 is listed with "normal" price. https://rigolshop.eu/products/oscilloscope/dho1000.html |

Prices are the same here in Canada but some models are not in stock for immediate shipment. --- Quote from: TurboTom on December 01, 2023, 04:11:29 pm ---While the timebase adjustments work more or less correctly on my black-friday DHO1000, the input sensitivity encoder works okay when turning clockwise, in the counterclockwise direction it frequently skips an increment between two detents and changes the value by two increments upon the next detent. --- End quote --- I can't reproduce the same issue, you are talking about turning the V/mV dial counter clockwise right? I had one time where it detented and I didn't see a value change, but that was after about 10 turns back and forth with seemingly normal behavior, and may have been my imagination. If I speed turn the dial either direction there is no obvious odd behavior. The only minor thing I noticed is if you are already at 500uV and turn the dial to go lower, the waveform will clear and sometimes glitch with spikes, though there won't be a trigger off of them. The previous mso5000 would pop up "over limit", this one doesn't which is fine. |

My DHO1074 was delivered, ordered from rigol.eu firmware : 02.04 hardware : 2 build : 2022/12/14 calibration date : 2023/3/28 The offer include the free RLU-01 option, but is not activated, and in the box there is no key for it. I asked them by email, until now I have no reaction. The encoders are working "almost" fine. Sometime the behavior is like TurboTom said ... it skip some detents and the next is "doubled". But for me the timebase is the problem, the input sensitivity is OK. Can't be reproduced all the time, and not the same detent. I hope that is a problem of software. I will update the firmware and will see. |
