Hi tautech, Its the SDS1102 CNL, has the last firmware, its both traces that go awol, did it yesterday while taking a single shot of a psu at power on, set the trigger level and vertical and timebase, scope waits for triggering and nothing happens after a trigger event. doesn't matter what vertical channel is used, Adjusting the trigger and repeating the trigger event doesn't do anything. Change trigger to auto and there is no traces, both channels are active according the front buttons, you can play with the vertical and time base settings all day, buttons and menus work normally, the traces are not coming back unless its rebooted and then it will behave until the next time, of course I wont know when the next time will be because this is random, some times it works just fine, sometimes it has a fit for some reason. The odd thing is when this happens I can still do a screenshot to a usb stick, so I can save a nice picture of nothing ;D I just accept it as a quirk but its a good excuse to get get something new, don't need a super advanced over complex scope, just something that works though four traces would be nice. The SDS1102CNL was my first digital scope, before that it was a tek 2236 and believe it or not, a telequipment D43R dual gun crt scope, non of this 'alt and chop' rubbish ! ( R designated rack versions) that I rescued from scrap, came from a national standards lab, once restored it doubled as a scope and room heater, also a telequipment DM63 analogue storage scope, there's also a hameg 20mhz something in there somewhere but I wanted something more up-to date though i will admit I was dragged into the world of digital scopes kicking and screaming ! -- |

Hmmm, not saying it’s the same or similar issue but have a look here: https://www.eevblog.com/forum/repair/sds1104x-e-intermittent-glitches-and-now-dead/ Know exactly where you’ve come from as my first scope was a Telequipment too, a D83. We have a class set of CNL all AFAIK still working since we supplied them in 2013 so the problem with yours will be of interest if you can find it…..I guess you’ve already tried a Default. |

I think by now the default button is becoming worn out, thanks for the link, when I get time I'll tear it apart and see whats going on. Given how things go with me, now that I have mentioned the problem, it wont show up for a while, its not really a big problem though, if it cant be resolved or I cant be bothered going to board level then I will just grab a new one, it really has earned its money, did so in the first few days of using it years ago so I can say its owned me no money. Thought going digital would be a big learning curve but the way the scopes laid out and the menu on it made the transition pretty easy, the only slight negative is these things are so lightweight these days I have to have the scope fixed with a velcro strap through the handle so stop it tipping off the shelf if a test lead gets snagged, never had to worry with the ol D43R, if that came off the shelf it would have taken me with it. -- |

--- Quote from: Electroplated on August 09, 2022, 10:07:25 pm ---...... so I'm looking at the SDS1104X-U to replace it, that's based on the layout of the trigger options being buttons instead of in the trigger menu. --- End quote --- The X-U are a budget version of 4ch X-E and not in the same class being only a 100 MHz design vs the 200 MHz capable X-E. If you can stretch the budget to the X-E get one as the feature set is much deeper so it's a scope you may never need to upgrade depending on how much time you need spend in front of a scope. Attached is a comparison chart prepared by member rf-loop however the new Logging and NTP features aren't shown for the SDS1104X-E. |

If you include image using its original source address (not some old copy from EEVboard etc) there have been over half year new corrected version ;) ;) and then about datalogger in SDG1004X-E models * ( Here more about datalogger, but sorry chingfinglish language ) * |
