Remarks:
The adjustment of trigger signal source while the Unit is in "AUTO" is based on the following points:
1. If only one channel has input signal, then set the signal input channel as the trigger source.
2. When more than one channel are used, the auto setting function sets the vertical control of each channel
and uses the active channel with minimal number to set horizontal and trigger control.
3. If no signal has been found in all channels, then use CH1 channel as the trigger source.
