In the thread above there is an indication that there are many differences between DS1074Z and DS2072A in terms of features.
But these differences are caused by the software.
Strictly speaking, the DS1074Z should be able to do everything that the DS2072A can do, just less B/W and sample rate.
In the current SW implementation there is much differences, but for me it is hard to believe that Rigol would not be able to make all DS2072A features available in the DS1074Z.
The HW in the DS1074Z is good enough to support all of the DS2072A features!
In fact it even has 4 analog channels. If they would just make the software feature complete, this would be the best scope out there if you don't need more than 100 MHZ B/W.
You are making some sweeping statements/assumptions here.
Yes, no kidding. Along with a whole lot of wishful thinking.
Be ready for all the replies to the contrary.
Well, I'm not sure it's worth the trouble. Apparently, he has no concept of product differentiation, and that a manufacturer may have valid reasons NOT to make the feature sets identical. Regardless of how hard that is for him to believe. Or the fact that while they are similar, they don't have exactly the same hardware, and thus may be more limited in capabilities.
What he should be saying is "
I don't understand", because he doesn't. Or that he finds it disappointing. That's certainly a valid sentiment, that many of us could get behind. Instead he's making proclamations of how he thinks things should be, because that would be his preference. He started out by claiming they
were the same, then when corrected, shifts to
they should be.
I'd certainly like it if Rigol added CAN decode to the 1000Z-series, but they've specifically told me they won't. And lack of time-stamps on segmented captures on the 1000Z is something I've been told they
can't add. Probably some internal architectural detail they're not about to share.
Saying "
it's just software", and "
it should be able to", and "
it is hard to believe" just demonstrates a lack of understanding of how things work in the real world. And is a denial of the reality of the limitations of products that exist.
When we evaluate and discuss the variety of scopes that are out there, we explore what their capabilities actually are. That's a learning process, but it let's us weigh the pro's and con's, and select which unit is most appropriate for our specific needs. The needs aren't the same for everyone, so neither will the devices selected be. Making suggestions to manufacturers about features or capabilities we'd like to see supported is appropriate. As is criticism of limitations we feel unnecessarily reduce their value to us. However, insisting that "
strictly speaking", things should be such and so, helps no one, including the person trying to decide which unit is right for them. Who, as a result, winds up never making any choice at all.
