1 review for Siglent SDS2104X PLUS 4Ch, 100MHz, 2GSa/s, Super Phosphor Oscilloscope

  1. bmcintosh (verified owner)

    Purchased the Siglent SDS2104X Plus as a replacement for my 2014 model Rigol DS2072A. Very happy with the Rigol apart from the font used for all on screen measurement being so small that I was needing a magnifier to read it. PC software access never worked nicely. I suspect the latest Rigols are better. It served me well but the Siglent is a big leap forward. Yes it costs a bit more but the user interface is stunning in comparison, and whilst tech specs are obviously a key to selecting a purchase, it is the UI that you use every day that can make it either a misery or a pleasure to use.

    Large screen (and with VNC on my double width 30 inch PC monitor I reckon you can see the font sizes in Timbuctoo!). Touch, mouse or use the physical buttons – all work intuitively smoothly.
    The specs speak for themselves so not much to say here but I have two gripes. Keep them in perspective as I have nevertheless rated the scope 4 star (might have been 5 otherwise). One is that the cooling fan, although much quieter than most test gear I have used, has a tiny little clicking sound, noted by many on EEVBlog. Not worth a warranty return since it seems most of them do this and its not exactly loud, just ever so slightly noticeable. In a commercial lab you wouldn’t actually notice, but if you’re in a quiet place working from home where it’s the only test instrument in use then marginally irritating. A much bigger gripe for me is that there is no “Average” mode on the Acquisition menu. I am used to hitting one button to try a smoothed out trace which I may continue to use or take off again. On the Siglent you need to set up the channel, go into Math, set up a math function on your chosen channel, then go back to your channel, hide it so only the math is on the screen. Sinc the math is post processing there is a pause after each sweep while it does the average. Oh, and there are only two math channels anyway to share between all all four inputs. Grrrrr ! To be fair, a real nice feature is that once in the math menu, the UI again is really nice with a great custom function building screen.

    A review wouldn’t be complete without mentioning the attention given by the crew at Telonic – attentive and helpful – a model of customer service which I put to the test because of some delivery hiccoughs with the courier. Effective and efficient – thanks team Teloonic.

    In summary, check the spec, if it matches your needs don’t hesitate to buy this well designed instrument. Look at some of the online tear-down videos of Siglent scopes and spectrum analisers if you are in any doubt about build quality – its really good.
