new killer scope in town - a true game changer from R&S - RTB2002 & RTB2004

There is another, overseen fact why RTB2000 is very silent. It is not very powerful scope, processing power wise. It is quite simple scope, and R&S did excellent low power design, in a fairly large, nicely airy case.
Combine that with nice fan running low RPM and you have a winner.

It is all about power. Siglent SDS2000XHD is even more quiet than RTB, for instance, but SDS3000X HD in same case is not as silent as SDS2000X HD. Still good but not as silent as SDS2000XHD.

Same as RTM3000 is not as silent as RTB2000. More power.

Scope with "little processing power” that has real-time digital filters in math, unlike the “more powerful” SDS2000x+ which does not have them due to lack of processing power.  ;D

Who mentioned SDS2000x+ ?

I was comparing how R&S RTB2000 is quieter than RTM3000 in a similar case, and gave a data point how also with other manufacturers, for example  Siglent, it is all about power density: If you stick more power in same case it is going to be hotter and more air evacuation is needed.

And, yes, RTB2000 has very limited processing power. It also have only 10 MPts of memory per channels, measurements work from decimated data sub buffer and FFT is only 128kPts.
It is literally simplest scope R&S makes, if we exclude old inherited Hameg 1000 series.

And I was praising R&S product: very quiet, very good low power design, good thermal design, a winner... All compliments, not a single bad word.

Fact that it is literally 2nd from the bottom product in R&S scope gamut is just a fact. And instead of R&S making cheap crap, they chose to make product that is relatively simple but good quality.
And it being simple is not even a bad thing. No need to have complexity if you don't need it. For some use scenarios simple is a plus, not a minus.

And price vise, if you are going to compare, fair is to compare with other scopes price for price...  Fully loaded RTB2000 (full bundle)  is 3600 € scope...

Best,

In fact, having both scopes (RTB2000 & SDS2000X+), I most often use the RTB, because its screen and user interface (responsiveness and thoughtfulness) are significantly better than  SDS2000X+.  And in 99.9% of cases its functionality is sufficient to complete the assigned tasks. How often does someone need 200 megapoints of memory? Or the most accurate FFT using 2M samples?

  But if I need something that is not in the RTB, then the SDS2000X+ comes into play, which can do much more, but is not so convenient to use and has a laggy, unresponsive user interface (if you use hardware controls. There are no such problems when using touch screen).

The RTB2000 is quite an old, simple, but very thoughtful and very well made device. Although its price with a full package of options is very high compared to Chinese oscilloscopes, of course.

Which 7200E? :)
RTB2K-COM2

P.S. Remarkable is that they have "student offers" which make this wise equipment accessible to a price comparable to chinese offers.
