Viewing Dig
ital Channels
The various ways of displaying data from the digital channels help you analyze the signals. Digital channels store a high or
low state for each sample.
Logic high levels are displayed in green. Logic low levels are displayed in blue. When a single transition occurs during the time
represented by one pixel column, the transition (edge) is displayed in gray.
When multiple transitions occur during the time
represented by one pixel column, the transition (edge)
is displayed in white.
When the display shows a white edge, indicating multiple
transitions, you may be able to zoom in and see the
individual edges.
When you are zoomed in so far that there is more than
one pixel column per sample, the uncertainty of the edge
position is indicated by l ight gray shading.
NOTE. When the light gray shading is displayed, use
MagniVu.
