Hi Wenchao,
By default, the "Scope" block might display signals from Channel 1. If you want to change the active display to Channel 2, you can do this by configuring the "Scope" block settings in the following manner:
- Double-click on the "Scope" block to open the "Scope" window.
- In the "Scope" window, click on the 'View' menu. Select 'Configuration Properties' from the dropdown menu. This will open the Scope Configuration Properties dialog.
- Navigate to the 'Layout tab' and change the Number of displays to 2 (or the desired number of channels) either along the rows or the columns.
- Navigate to the 'Display' tab and change the 'Active display' to 2 (or the desired channel number). Save and Clsoe the 'configuration properties'.
You may refer to the following MathWorks documentation links to have a better understanding on configuration properties and active displays of scope:
