Which other scopes? Given the amount of RTB2000 videos already out there doing the other scopes may be more informative.
Keysight 1000X, Siglent 1000X-E, and I haven't done the Hameg or the GW Instek either. That four scopes that come before the R&S.
I also like the Keysight 1000X and the Siglent 1000X very much. On the other side: Keysight already delived a lot of videos during their scope month. I believe that the users expectations will be fulfilled with both scopes. I don't expect a sensation here.
Different with the RTB2000. The questions here is: Are we at the beginning of a new development cycle? After increasing samplerates, screensize, refreshrate and memory step by step for the last 20 years: Will vertical resolution and sensitivity be the feature, that will be improved by the vendors for the next decade step by step? What does the expanded dynamic mean for the measurement of THD, SNR, etc.? Does the RTB2000 fulfill the expectations?
