After using the trigger capture communication signal, the oscilloscope software enters the decode mode by selecting the corresponding communication protocol, such as ―UART‖ or ―IIC‖. Clicking on the protocol menu item, ―On‖ appears in front of the menu item, indicating that the communication protocol is used for decoding. Clicking ―OFF‖ will terminate the decoding. After the communication protocol is selected, click the right mouse button in the waveform display area. The ―Setting the decode parameters‖ option in the right-click menu will be activated and changed to the usable state. Click ―Setting the decode parameters‖ to pop up the protocol parameter setting window. Usually, the software will display this setting window actively when the selected protocol is selected for the first time to remind the user to complete the parameter setting. Then, during the use, you can also use the options in the right mouse button menu to call out this window for parameter adjustment.
