I got higher end equipment myself but this combo seems excellent for the beginner, for teaching and really for most. We can do almost everything up to RF work at HAM level. Lots of talk about the intuitiveness of instruments in this thread but what about the complete solution? Get those two, connect with the supplied USB cable and DONE. Start focusing on the actual electronics you want to do instead of the instruments. I don't really get the budget constraints. The MSO5074 appears to be €799 at eleshop.eu. The SDS1104X-E is €429 and SDG1032X is €289 total €718 so why would it be out of budget? Down the road you will be buying new toys. Do not think what you buy today, no matter the budget, will be the last thing you buy or upgrade :-). But in reality this is a very strong offer that many will never outgrow. --- End quote --- Yup, exactly and a very capable pairing and both hackable too if you must. ::) With the 2ch AWG and XY mode in the SDS1104X-E we can also have a play at curve tracing too: https://www.eevblog.com/forum/testgear/fooln-around-with-dso-awg/ |

Apart from its 1.5-3V limit and slightly lower sampling rate, what are its limitations with respect, say, a SDG1000X? Thanks. --- End quote --- Datasheet time ! SAG1021I>P13. These have the benefit of an isolated output, ie. not referenced to mains earth. https://www.siglenteu.com//wp-content/uploads/dlm_uploads/2021/08/SDS1000X-E_DataSheet_EN04D.pdf --- End quote --- This is the datasheet for the scope. Even searching inside it for the WG, there is basically nothing. Is there a datasheet for the SAG1021i? I'm having trouble finding it... Thanks. |

Both the earlier and later versions have the same spec of which starts on P13 and continues onto a good chunk of P14. --- Quote ---Even searching inside it for the WG, there is basically nothing. Is there a datasheet for the SAG1021i? I'm having trouble finding it... Thanks. --- End quote --- No. SAG models fit a # of Siglent scopes but as they are not a standalone device but instead optional to the scope which houses the UI for which to control it all specs and usage instructions are included in the scope datasheet and user manual. Here, I've plucked out the SAG1021I specs from the scope datasheet: USB AWG Module (four channel SDS1004X-E series option) Channels 1 Max.

Just a few months back features were added that we never imagined would be, now to make SDS1104X-E one of the most capable scopes in this price bracket ever produced. |
