Excellent choice going to Pico. Once you learn it, you will see why it is the most powerful automotive scope in the world.
Our comprehensive PicoScope specific help/training is in our Picogroup members only areas. Picogroup members are those who have purchased their PicoScope package from Autonerdz or subscribe to the service.
But here are some brief answers:
Quote:how do i select the channel before choosing an automotive preset?
You don't. The automotive presets open a data file which completely configures the scope the way it was when the data file was saved. The automotive library of captures and information is very useful for viewing examples and reading the documentation. However, we don't recommend that they be used in the field, at this time. Most of those data files are from captures made on older model scopes and are not optimized for good performance with the 3000 series scopes. The library will be updated in the future...so this may change. Right now we recommend that you learn to set up the scope manually. This way you can configure each channel as desired and adjust for the optimum performance. Then save your file and use that for similar future requirements. You can then build your own custom library of setups and captures that will serve you well.

You can save your file in an image format directly from PicoScope but this only captures the scope grid area. Most of us prefer to capture the entire PC screen area and then paste into an image editor. Then we can crop, resize, add notes, etc. This also allows you to make images that show the entire PicoScope screen with the control bars that display the settings.
