Step 11: One of the most powerful display modes in the 11801C is
color grading. Color grading adds statistical information to the display
by varying the color according to the number of hits" for a given pixel.
Color grading adds a third dimension to the persistence display and
allows accumulating data in a statistical database for later analysis with
histograms or masks. To turn on color grading, touch the Persist/Histo
grams selector, touch the Color Grading selector in the pop up menu,
and touch the Exit selector to remove the menu. For more information
on color grading, see Setting the Persistence Mode on page 3 44.
Step 12: After enabling color grading, measure eye pattern characteris
tics such as risetime, jitter, and noise in the Statistical Measurement
Mode. To turn on Statistical measurement, press the MEASURE button,
touch the Measurements selector, touch the Statistics Mode selector,
and then touch the desired measurement, for example risetime. For
more information on statistics mode, see Measurement on page 3 135.
