It's almost like 2N3055 wrote it, his assumption.
Rigol throws a few models on the market and the model that hits the nerve and sells well is halfway maintained.
See DS1000z and MSO5000.
These have probably received the most updates.
The MSO5000 in particular was a hit, 8GSa/s max and a fully-fledged 2-channel AWG except for the output level, you won't find that anywhere in this price range to this day.
But these were lucky hits, Rigol doesn't seem to know any model strategy or even proper model maintenance.
Now the new 12Bit models, starting with the 4000/1000 models a year ago.
I had a 4204 to test at the beginning of this year and now for a few weeks the 804.
And I was surprised that nothing has changed in terms of the software.
Especially as a 4000 owner I would feel like a fool, except for the hires mode and a few more decoders, the biggest model is no different from the smallest.
On the other hand, you could have used the year to incorporate various improvements and additions, this is not the case.
So the feeling remains that Rigol has simply released a few "prototypes" and the "real ones" are yet to come, with customers serving as beta testers.
This is simply not serious behavior.
Of the four models, two of which I know, I think the 800 series is the most suitable.
The price/performance ratio is right (apart from the current 40% less promotion on the 1000).
