content: Welcome to the forum.Have you considered the Siglent SDS2000 series:http://www.siglentamerica.com/prodcut-db.aspx?id=25&tid=1&T=2For your requirements the SDS2104 and DC (decode) option would match.BUTSiglent are still running a promotion for this series:http://www.siglentamerica.com/USA_website_2014/Documents/News/ME-End_User_Promotion.pdfFree bandwidth upgrade: buy the 70 MHz version and receive the 100 MHz model.Then you have some money left to purchase the options you need.There is a large thread on the series:https://www.eevblog.com/forum/testgear/siglent's-new-product-msosds2000-series/

content: Quote from: veeru612 on April 09, 2015, 10:01:04 pmThe included software (UltraScope) is not great, but it does work. It's more of an on-screen representation of the scope, with many of the functions available (and many not available).However, a member on here wrote a *much* better piece of replacement software, that actually works really well:https://www.eevblog.com/forum/projects/software-tips-and-tricks-for-rigol-ds200040006000-ultravision-dsos/I have had good experiences with my Rigol products, but I don't have as much experience as many others here. I have a DP832, DG1032Z, DS1054Z, and a DS2072A that will be here next week (so, I guess I don't have that one yet). All have excellent build quality and work well. Rigol is good with regular firmware updates on most of their products. Their software is not great, but either is most software that comes with test equipment.I believe Sigrok (http://sigrok.org/) works with most of the Rigol scopes now, too.

content: Here is a thread with people talking about their complaints about the DS4000 series, decide for yourself if anything is a deal breaker there:https://www.eevblog.com/forum/testgear/rigol-ds4000-series-owners-please-tell-me-everything-you-hate-about-em'/I think most of the complaints are comparisons against much more expensive scopes. Sure, for 10k you can get a lot of scope. Rigol, on the other hand, provides a ton of value for the money.

content: I'd look for a second hand / refurbished Keysight 2000 or 3000 series. The Siglent SDS2000 would be a good choice if the firmware was finished.
