Tips
 For a better observation of the waveform details in the vedio signal, you can
set a larger memory depth first.
 In the trigger debugging process of vedio signals, the frequencies in different
parts of the signal can be reflected by different brightnesses as RIGOL digital
oscilloscopes provides the multi-level gray scale display function. Experienced
users can quickly judge the signal quality and discover abnormalities.
