Using Masks, Histograms, and Waveform Databases
3- 152 CSA8000B & TDS8000B User Manual
Masks are created by connecting the points independently of the order they are
entered. Points are connected by sorting the points in left-to-right order and
grouping them across a diagonal from the left-most point to the right-most point.
If two points share a horizontal position along either the left or right edge of the
mask, the diagonal runs from the top left-most point to the bottom right-most
point. Points below the diagonal form the bottom boundary of the mask; points
above it form the top boundary. Use this procedure to create a new mask:
