Results are measured between two channels. If they both have about the same error, it will cancel.
Went and checked all the channels on mine using the internal sig-gen, they don't look as bad as Dave's but there is definitely a change when the attenuator kicks in. In this case I grabbed a capture from each side of the range switch (~150mV, depends on the calibrated gain of each channel) using fine vertical gain adjust. Screenshot windows are due to me being impatient when capturing (they're confirming the previous screenshot).
I seem to recall this coming up for other scopes - was it Siglent that sent out repair kits to those brave enough to open their scopes up?
Distortion is mostly visible with 1kHz square wave, so for most measurements -and the fact that one now knows the problem- it isn't a real problem at all.
it means that Rohde&Schwarz, know about it from the past and correct problem IN RTM Series.

I'm sure this is known for a very long time, maybe since the very first square wave was fed into an oscilloscope.
They probably don't see it as something that needs to be "corrected", just minimized.
Correcting it 100% might be very expensive to do.

I am in love with Rohde&Schwarz. Dreaming about RTE1024. New models like RTO6 or MXO4 in my opinion lost the impression look like very good etremly high material using RTM2000, RTE1000, RTO1000, RTO2000 and the best RTP which is probably looking older, today trend nevermind if you have tek or keysight or r&s, they will looks the same only logo, and buttons. We had one RTP at work, no RTO6, but RTP has hardware real-time exellent top spectrum anylaser, and can work like MDO4000, or in any possible configuration. For me RTE will be the scope for 10 years. But now I use mix of RTB2004-COM4 + MDO3054 full opt. + 3GHz SA. MDO is slowly, fft in it don;t use, but has Power Anylasis, ADVANCED MATH means that you can create any formula, Have editor in AWG, SA, FastAg with palletes is wrong make, RTB gives me possibility to set color separatly of course the color is not only change color, it is enable color gradation of waveform like false colors with do job. RTB is fast, has user friendly GUI, fantastic multi touch screen of 10 inches, both have 10M. FFT in RTB is great, not everybody knows, that, if you set e.g. Waveform palette false colors, the FFT also will be like in RTM3000, RTE1000. Pattern generator is very useful for me. Has some filters the RTB? I hav HMO1002 now RTC01002 lowest scope in R&S, and it has filters. But on the other hand RTB2004 does cost much more less then RTM3000-COM4. Limitations are normal

So I get the impression reading through this thread a bit that the R&S RTB200X scopes offer less base functionality than the Siglent SDS200X Plus scope and about twice (or more) the price? Considering the problems this series has, why would someone buy one of these today? To get a Rohde & Schwarz label?
(just being cheeky)
All in all I'd be interested in an amplitude versus frequency plot to see what the frequency response of the RTB2004 looks like.

And I thought it was meant to be humorous... Which is not in contradiction to being sarcastic at the same time, mind you ...
Just to make sure which part is sarcastic:
- you love R&S so much you dream about it?
- Your opinion on scopes you mentioned..?
See, it is not so clear...
Thank you for your opinion about my mental health... Is as as valid and opinionated as your opinions on scopes.. But thanks anyways.. Good intentions are always welcomed even when a bit misdirected.. And being an adult person is overrated.... Kids have much more fun..
Okay, make fun of me, make fun of me. I'm sorry for this statement, it's just that your previous post brings nothing to the topic except that it may be upsetting to some users. Maybe SDS2000X Plus is better than RTB2004-COM4, I don't know, it's hard for me to be objective and honest here, because I don't have or have access to SDS 2000X Plus. I did not choose Rohde & Schwarc for the emblem, only because I like these oscilloscopes and their design, after working on RTE I knew that the manufacturer focuses on the best materials and electronic components which translates into quality, the oscilloscope is well thought out, I also have HMO1002. interesting and useful solutions like Virtual Screen. I assume that this sensational Siglent 2000X HD in a full option configuration costs much more than the RTB. Since he is so cool. Everyone has a budget, a different one will buy something for $ 1500, another one for $ 6000- & 7000, and another one for $ 25000. There is no point in arguing. Apart from R&S I have a Tektronix which is also great, Siglent also but only SDS 1104X-E, in my opinion a very good oscilloscope. I'm sorry if I offended you, What's wrong is not me.

I was jesting a little but wasn't making fun of you, as a person.
If you got offended I am sorry too. It seems I have problem with sarcasm, you have problem detecting humor.. We are not perfect..It's only human. Important thing is to stay civilized and work out the differences..
Just a note, one might argue that your post also added nothing useful to the topic. That is why a slight tangents are allowed in discussion.
RTB2000 is similar and was made to look alike 3000/4000 series but have seriously less capability. FFT on RTB2000 is also not perfect (there is a separate topic discussing just that) and not same as RTM3000 that has spectrum option.
User configurable colors are useful and other scopes have it too. One thing I really like on R&S is user configurable palette for color grading. Especially useful is reverse palette, that shows rare signals most brightly.... I wish more scopes had that feature..
R&S higher end devices are excellent but expensive. Budget always exists, but it is how much you get for your money is what changes all the time... That is why I don't believe in blind brand loyalty.
And yes, you were wrong a bit. And so was I. We both apologized.
I will not pollute this thread anymore with this detour. If you feel anything is unresolved, please let's continue with PM.
Sincerely, all the best.
