You forgot to quote: On top of that you make a fool out of yourself by ridiculing other people's workflow.

I appreciate your opinion very much.

I mean to ask with respect to the zoom out/history functionality that I asked about in my previous questions?
So all the current siglents behave the same way?

Yes, it's Siglent's, LeCroy's and Picoscope's design philosophy as zooming in is a more powerful use of a deep memory architecture than zooming out.
There is a bigger picture to consider why some DSO's are this way as sampling rate, memory depth and WFPS rate are all somewhat dependant on one another and careful study of datasheets can reveal how all brands make tradeoffs in their designs to maximise performance.
None are 100% right or wrong only different to operate and get the best from.

However a deep memory DSO is highly desirable in order to have the greatest versatility.

Now you are contradicting yourself. Not being able to zoom out lessens the versatility and seriously slows down some type of measurements. And I repeat: there is no trade-off to be made to support zooming out. R&S shows that by supporting all acquisition modes.

It is clear you do not understand the tradeoffs when they are quite clear in a R&S datasheet.
Study enough datasheets with the knowledge of how different brands do capture management strategy when using ADC/FPGA's and the tradeoffs stick out like a sore thumb but they are best left for the observant reader to discover for themselves.

This is not about brands but design architecture and implementation.
Maybe take a deep breath and read and fully comprehend my post above.

Please point them out and I can tell you exactly where your error is. There is absolutely nothing Siglent's memory management can do which the R&S scopes  (RTB2k, RTM3k and RTA4k) can't.

Edit: two days later and still no explaination from tautech on how Siglent's memory management is better compared to that found in R&S scopes (which caters all modes).  8)

Some people simply don't want to listen.

They put their hands on their ears and go "nananananananananana" when sombody says that Siglents aren't gifts from the gods.

Me? I say there's no excuse for not filling the entire memory when the 'scope is stopped.
