Looking at the manual for R&S's HMO series of oscilloscopes (comparably in price to the RTB2000), I see that they offer two kinds of math functions: "Quick Math" which is just add/ subtract/multiply/divide and "Formula Editor" which has pretty much everything you can think of. Since this scope seems to just have the "quick math" functions, I wonder if R&S plans on releasing the "formula editor" functions either as an add-on or in a later firmware revision. I hope it's the latter reason and they just need time to re-work the math functions for 10 bits instead of 8.

The brochure states that the HMO1202 is in a different math classification "Basic / (math on math)" vs the RTB2004 which is "elementary". I don't understand the reasoning but it seems that is the way it is. I too wonder if it is a technical limitation or a marketing choice? And if the latter, might there be a future option?

Perhaps R&S Rich has some insight?

The current math capability is the basic math functions described. Having said that, I really appreciate getting additional feedback and will absolutely pass this on to the design team Germany. No promises that it will be implemented, but the more feedback we hear the more likely something is to happen, so please don't hesitate to keep passing it on.

Yup, that's a bummer. I have a DS1000Z and while the new RTB2000 is superior in many ways, I know I will miss the more advanced math.

The Rigol has more operations ( addition (A+B), subtraction (A-B), multiplication (AxB), division (A/B), FFT, A&&B, A||B, A^B, !A, Intg, Diff, Sqrt, Lg, Ln, Exp and Abs, low/high/band pass filtering.) according to the manual and can also cascade operations once with one intermediate variable (so you can do Ch1+Ch2+Ch3) - they call this "Fx operation". While I see how arbitrary formulas could be considered a differentiation feature for higher scope, basic maths as in the Rigol (more operation and basic cascading) are par for the course these days (even if the Keysight 2k don't do them either...).

I personally have used the cascading, intg, diff and will miss them if they are not in the RTB2000 (which they clearly are not right now).

It looks like there is also a deficit in triggering types (I haven't looked closely). Things like N-th edge or setup/hold are useful.
