--- Quote from: joeqsmith on November 11, 2015, 01:15:04 am ---The sent me all new knobs for the old Waverunner and these have not been a problem. Very tight fit. I have not hand any problems with my old 7200/As or my WM. Said it before but the case on the Waverunner is not the highest quality and don't get me started on those connector failures. I do like the scope now that I have had it for a while and I will say that LeCroy has really pulled through and helped me out with it. --- End quote --- Yes, the Malaysian vendor who built the first WR(M)Xi did a pretty poor job with the chassis and the quality of the plastics parts, but the later production runs (made in USA) were much better. I doubt your replacement knobs will fall off anytime soon. --- Quote ---Even my old 7200s are fairly responsive when you consider their age. I was not impressed with that Waverunner when I first got it but again, adding the RAM and putting the SSD in it really woke it up. You know it's been in there almost a year now? Not bad for something that was not going to work. :-DD BTW Wuerstchenhund, did you end up installing that SSD in yours? If so, any problems? --- End quote --- Well, I did get a Transcend PSD330 IDE SSD (the same one you used), and it's sitting here and waiting to be installed for a few months now ;) I'm pretty sure it will work, though, as Transcend fixed the UDMA issues that occurred with the older PSD320 in these scopes. --- Quote --- --- Quote --- --- Quote ----Crappy probes where the pogo-tips break off in the grabber hooks. --- End quote --- Never happened to me. And I have not exactly the most sensitive hands. --- End quote --- :-// I have no complaints about their standard 10X probes I have used. I have had to repair some of their GHz differential probes that had the tips broke off (not by me). --- End quote --- The hand piece housings of older AP-033 and AP-034 Differential probes are often broken (the underside tends to crack), however a new replacement housing is $17 or so (and its the newer, improved and more modern looking design which won't crack). Probes without housing or with parts of the housing missing can often be found on ebay and are a good way to get a very good probe for cheap. --- Quote --- :-DD Stupid auto cal anyway. --- End quote --- Yes, it would be better if it was opt-in (i.e. off by default until enabled). BTW, the Siglent-made WaveSurfer 3000 doesn't do auto-cal any more (I guess they figured these days its no longer a benefit for a 4GSa/s ADC) :) |

Once. Around 30m of being on, it does one very quick self-cal cycle and then comes back. I think their method is to simply do it once the instrument is to temp. |

If it's in anyway a similar UI, this feature is within one of the Utilities pages. |

It wasn't the case on the one I had for a day (it calibrated after power-up and that was it), but then this has been shortly after they came out so I guess it might have been introduced with one of the several firmware updates this model got. I think that's a good change, calibrating after a 30min warm-up is a much better than calibrating when the scope is cold and then seing drift the parameters when its warmed up. --- Quote from: tautech on November 12, 2015, 02:01:57 am ---If it's in anyway a similar UI --- End quote --- Thank god it isn't ;) |
