Hi Boguslaw,
PicoScope evolves.
PicoScope has a LOT of capabilities and features. That's why we have so many hours of tutorials for our Picogroup members. Each one covers one or more features. Obviously, we cannot redo all the tutorials every time they change a feature or move a button. So....
The tutorials are a progression. We do one on a feature and then later if that feature is changed or vanishes, a later tutorial tells you about the changes. When you watch them all in order, you'll see the evolution.
So, when watching the tutorials, don't fret if you can't find a feature or button in your current version that is shown in a tutorial.
These tutorials are separate from our YouTube channel stuff but the same principle applies. The PicoScope introduction you watched on our YouTube channel was done with an old build that had buttons for reference waveforms and math channels. Shortly after this it became obvious that, with the explosion of new features and capabilities, we were going to have way too many buttons. The decision was made to move to menu driven function selection to preserve scope screen real estate. This was a really good call IMHO. Most features are only two clicks away. Buttons were just clutter.
