Ah, Bernstein.. 8)
I have the other one and was a little bit disappointed from the content.
More I like the short tek "book" about scopes.

Working through the exercises in order - so far, very straightforward and signals are exactly as described. I'm using a small screwdriver to (carefully) turn the knobs instead of using my fingers. I like that they have a nice positive "click" at each position.
I also noticed that they labeled the flooded ground point a "Crocodile area" :) (Note that the German for alligator clip is "Krokoklemme," so this makes perfect sense to me)
There might be one small typo: in section 2.4.5 it says "Messen Sie das „SPI SCL“ Signal mit einem Tastkopf." (Measure the SPI SCL with a probe).
I think they meant I2C. The SPI pin is labeled "SCK" and is idling low. The I2C SCL signal is idling high looks exactly like the one in the manual.

Was working on 2.4.7 (Window trigger) and got something that looked more like a differential CAN signal than the screenshot in the manual. Then I realized I was plugged into the wrong BNC connector :palm:
Probably worth noting that if you're working straight through the manual, you should make sure the connector hasn't changed since the last exercise :)
Edit: this was very clearly stated by Batronix, I just wasn't reading the instructions :)

Ah, the slew rate trigger, on this I stopped yesterday...Must try it again.

OK, I was a little bit confused... ;)
When your first pic shows the right signalform, then I already got it right adjusted.
Because I stumbled over the screenshot (which is wrong titled, @Batronix) and over the sentence in the manual:
--- Quote ---If your oscilloscope supports it, you can also set the slope trigger to
"Outside" and set the time range to 140 μs to 180 μs and to rising and falling edges.
With this you should get all errors of this test signal triggered

This let me thought, it has to look like the screenshot (On top of that if you can see in the picture that the slewrate trigger was selected)....
