I'll do my best to keep up.
OK, here are a few feedback points for your product planners:
1. Probe sensing and 50 Ohm input go a long way to make the RTB the king of the hill in this segment. This "miss" is a hard-stop since it requires hardware. It's strange R&S decided to cap it there. You've come so far, why not the extra couple of resistors and a few more lines of code in the firmware to make it impossible to resist?
2. FFT's are commonplace in entry scopes now. To be truly useful, FFTs need adjustable scale ranges and peak and harmonic markers. R&S make some of the best spectrum analyzers so they know how to do this perhaps better than anyone else. So the way this has been implemented on the RTO and RTE scopes is truly excellent. A simpler version on the RTB (just like Quick Measure which is on all R&S scopes) would be truly icing on the cake. I would gladly take a 32Kpts FFT with markers over a 1Mpts without markers any day of the week.
3. One last point - make rubber corner bumpers and DC input an option so the RTB can be used on- and off-the bench.
Just a few ideas to turn this into the irresistible $2K king of the hill, and possibly, even the king of the road. Good luck.
