| Screen flickering on DS1052E |
| (1/7) > >> |
| kyren:
I'm not really sure if this is a problem or not, but I just bought a DS1052E scope and I'm noticing an odd screen flicker now and again. It's VERY intermittent, like maybe once every 10 minutes or so, but it seems like the whole screen goes white for a split second, then is fine again. Is this indicative of some dodgy connection somewhere? Do DSO scopes normally do this? Should I make a warranty claim? Any advice would be appreciated. |

It's a fault of some sort as that doesn't happen on my ds1052e. I have seen other people talking about getting a permanent white screen, maybe your have the same fault but it's intermittent. It does sound like some sort of bad connection or solder joint. If it's easy to return for warranty claim do that, might be a good idea to record a video of the fault and burn it to a CR-R and include it with the scope when you send it back. often when you return goods with intermittent faults you just get them returned 2 weeks later with "no fault detected" :( You could try give the scope a good shake, it's win-win. If it fixes the problem thats good, and if it makes it worse that's good too as it's easier to make a warranty claim |

You know, shaking it doesn't really make the problem any different. The problem is such that you could use the scope for an hour and not even really notice it. I contacted Rigol about it, and I'm waiting to hear back from them. It almost seems like it's a software problem because the problem doesn't seem to be tied to anything I can physically do to the scope at all. What firmware are you using? Could it be an issue that only happens with the more buggy 00.02.05.02.00 version firmare? |

mine is 00.02.02 SP2 i flashed it with the 100mhz firmware. If you plan to try that version on your scope, read up on the scope hardware and firmware version issues before doing it. There are issues with the newer versions being bricked with old firmware. I dont know enough about the versions to say if it's safe to try that on yours or not. If it's still under warrenty it's best to let rigol fix it than to play around with the firmware yourself and risk voiding the warrenty. |

It's hw version 58, so IF it came with one version lower of firmware, I would have already hacked it and gone to 00.02.04.01. Hw version 58 is fine with 00.02.04.01.00, but no luck because no hack has been found for firmware 00.02.05.02.00, so as of right now I'm still waiting for one. Something a little off topic, I was double checking something a second ago and I did something kind of stupid. At the DS1052E system info screen, I did the ch1/ch1/ch2/ch2/math sequence to check on the hardware version number, then backed out. Then later, I wanted to double check something else and I went back to the system info screen and did the ch1/ch1/ch2/ch2/math sequence again without realizing that it was already in the "extended" mode! I know I've been warned about pressing ANYTHING other than Run/Stop while in that mode, and I wasn't paying attention and messed up badly. The scope seemed to be working fine, I recalibrated it just for good measure, and it seems totally okay. The probe calibration square wave seems normal, and at the correct 3.0V, so did I screw something up? Edit: Disregard that, it turns out messing up the scope while in the extended info screen is only possible if you have an older firmware, it's a bug that they fixed in later firmwares. |
