Well, the calibration isn't worth much to me, but the newer hardware is. I believe the MSO5000 series was released at the very end of 2018 and this scope was manufactured at the beginning of 2019, 4 years ago. To me, this feels like it's from one of the very first batches. I'm also seeing some weird behavior that is difficult to tell if it is hardware or firmware related. Saelig just issued an RMA so I'm definitely going to take it. |

I am glad they took care of it. Your scope was roughly the same date as the one I have, from what I recall, the early production had very noisy fans. It was supposed to be fixed by the time your scope was produced, as the noise from mine was acceptable, not loud. Not sure what you mean by strange behavior, but in any event, I am glad you are getting it replaced. I agree with Fungas scope calibration is not as critical, but I also see the point that when you buy something new, you should expect something that was manufactured fairly recently, and not 4 years ago. The scope was in high demand back in those days, and there was a wait for delivery, so I am surprised that they found one of that vintage in inventory, it might have been tucked away in the wrong corner and they just located it during an inventory check. |

Not a big deal to me either way. The funny behavior was something I noticed on the very first boot with old FW, but I have the latest FW and it still does it occasionally (maybe 1 out of every 4 boots??). Here are channels 1 and 2 both connected to the probe compensation output. I have never seen anything like this on any scope before. The shape of the waveform also changes when I change vertical offset, when I have just a single channel enabled, and also shows up on channel 2 if channel 1 is off, which is strange. There're a lot of nuance in the behavior, but I fear it may be way off-topic for this thread. If this is not something before-seen, maybe I can start a new thread. Not sure if FW or something weird with the frontend ADCs. |

I assume they are each on X10 setting, and you press Auto to trigger it? I haven’t seen anything like that myself. Definitely a return back to the dealer. |

Using stock probes, but the channels are on x1 setting because it was taken right after a full reboot and and reset to factory default -- didn't bother to change attenuation setting (it doesn't matter in this case). I didn't press Auto, just adjusted the horizontal scale. Check out one of the videos I took. The behavior is pretty wild. Maybe I need to start a new thread to see if anyone has anything I should try the next time it comes up like this before this gets returned. Apparently, Saelig had to order a scope from Rigol USA before they can replace this one, so I have some time with it still. |
