Looks to me like you were testing with a signal that has 100 times higher frequency than in Rigol's demo. So you are giving the op-amp only a fraction of the time to recover.

There are limits to what the front end can handle, and you are exceeding them with your test. I can't see any false advertising by Rigol here.

Alexan:
No !  I did the voltage and frequency exactly as in the video!  Thanks to the forum, I found the answer to my question!  It's all about the different input amplifier circuit MSO5000 and MSO7000.  The 7000 contains an ADC input voltage limiter with feedback.  This can be seen when studying photographs of the input amplifier of these two devices from this forum!  In the video from Rigol, the model is 7000 and not 5000 as indicated in the title!  So Rigol is deceiving its customers by not providing them with complete information about the capabilities of its models!  Are there any guys with MSO7000 to check my output?

Then why did you show something else in the video you shared? It shows 10µs/div timebase, while Rigol demonstrates things at 1 ms/div.

By the way, if you want to share more data: Can you please use still photos (or even better, PNG screenshots) instead of the video? Watching the shaky video made me dizzy, I wasted a lot of time watching you in search for the signal, and had a hard time reading the settings on the screen. Thanks.

What makes you think that? The MSO7000 looks very different -- not only does it use a white enclosure, but also the screen size and connector layout are different from the MSO5000.

Please take a deep breath and review both, the Rigol video and your test.

Alexan:
Thanks for pointing out my mistake! Yes, when the frequency of the signal being studied decreases, the signal shape is displayed as in the video!
