Auto determines the trigger source according to the following conditions. If multiply channels get signals, the oscilloscope will use the channel with the lowest frequency signal as the trigger source.
If no signals are found, the oscilloscope will use the lowest-numbered channel displayed in Auto Scale as the trigger source. If no signals are found and no channels are displayed, the oscilloscope will display and use Channel 1 as the trigger source.
