The firmware is the same - but where are you going to get the daughterboard from?
It's a little secret I will reveal it someday, soon.
P.S. If the firmware is same on both DSO then why on DS1000z there is no Signal generator icons? Maybe it will appear after inserting daughterboard?
Hey, you are the one who claims to have a source for the daughterboard -- you better figure it out...
Seriously though: You claim to have one part of the required solution, but are not telling us.
But at the same time, you expect the forum to help you with the other part of the solution?!
