content: Hi,After noting Dave's conclusion that the Rigol DS1054Z jitter problems may not be totally solved with a firmware fix and that the root of the problem seems to be in hardware, would it be prudent to wait for a hardware revision before purchasing one?Thanks,Martin.

content: I sincerely doubt that Rigol will do a hardware revision because it is now good enough. I could be wrong.

content: I wouldn't call it half baked junk. Is it perfect? NO. Can you get better for the same money? No. Can you get better for more money? Of course.Aren't all those questions true about anything?

content: Quote from: wonna on May 03, 2015, 06:34:01 pmI think it's Bud being Bud. He spent a lot of time on the infamous jitter thing as did others including myself, but I don't think he actually owned a Rigol scope as such at any time. Happy to be corrected of course.Of course, you are looking at a scope that costs an order of magnitude less than an KeyTekCroy for similar specifications, something's going to give. There are, understandably, some situations where it's a compromise too much. But for student studies such as yours I would doubt you'd have ever encountered the problem. Or if you did, you would have learned an awful lot from it.

content: if you need a scope, then don't hesitate and buy the 1054Z it's really the best you can get for you money in the low budged category. and regarding the jitter issue - no worries, the software fix is good enough for everyone.i had to buy the 1054Z i couldn't resist after watching the reviews, and i'm happy i bought it - the user interface is good, it's fast, it has enough memory, intensity grading... it's a 400$ "scope jackpot" for hobbyists and young playersof course if someone is like "give me a $4k scope for $400" then that person won't be satisfied with it(those are the ones with the half-junk comments)
