Obviously not good to have metal pieces loose around in there... --- End quote --- Hi Sparky Sh!t , a rattle in my DS2072, and one retaining clip fell out :-- and another one rattling, I got it near the vent and working on getting that clip out, :-- :-- Now where are the loops?? What will you do? Fix it w/rebar-wire;D or an RMA??? I have already sent my DSO back Once. DS2A1425xxxxx |

--- Quote from: martinv on August 07, 2013, 03:24:46 am ---Check the fan. On my scope one of the loose parts stuck to the fan motor and was held there by the motor magnets so shaking didn't dislodge it. --- End quote --- Thanks martinv! That's a good suggestion. The loop could have lodged there, but I didn't see anything when I cleaned the back case. --- Quote from: SeanB on August 07, 2013, 04:54:49 am ---Very stupid to rely on the solder alone to hold it in the board. At the least I would make a new one out of a paper clip cut in half, pushed through the hole and bent over on the underside before soldering back in the hole. --- End quote --- I like this idea SeanB, a paper clip is probably almost an exact fit. If I repair it myself, I'll go this route! --- Quote from: Teneyes on August 07, 2013, 03:14:26 pm ---Sh!t , a rattle in my DS2072, and one retaining clip fell out :-- and another one rattling, I got it near the vent and working on getting that clip out, :-- :-- Now where are the loops??

I get the feeling this issue is more frequent than first thought! In your case, it is both retaining springs that have come loose? I could not get the spring out through the vent and had to take it apart. I looked around for my loop and never found it...it could still be in my unit, which is a bit of a worry, or has fallen out. I'm going with the latter because I inspected pretty thoroughly when I had the case apart. For now, I'll use it as is. The heat sinks are held on with thermal adhesive, so I doubt they will fall off in the short term. But I'm not sure about long term; the springs are there for a reason... Likely I will RMA it at sometime, but if it is no longer in warranty I'll do the mini rebar = paperclip fix :D Mine is DS2A1427xxxxx Good luck getting those loose parts out! |

I noticed a bug(?) when decoding RS232 communication with the DS2072: I have a RS232-like communication, with TX on channel 1 (named DC on the scope) and RX on channel 2 (named DP). Have a look at the attached screenshots: Serialdecode1.png shows the correct decoding for channel 2 on Decode2-RX. But this only works correctly if Decode2-TX is set to Channel1 (although it only decodes garbage from that because it has an inverse polarity). If I switch Decode2-TX decoding to Channel1 (like in Serialdecode1.png) or switch the Decode2-TX to off, it decodes the RX line wrong. Has anybody else seen similar problems? |

Everyone watch-out Do I dare turn it on and have the heat sinks fall off? Has anyone opened a DS2000 and seen any improvement in the spring-clamp anchors? |
