16.3.2 Analyzing the ADC
Add a slice line to the evaluation curve over the evaluation length. Add a second slice line
that is the unit distance below the first slice line. The amplitude density (ADC) is the ratio
(expressed as a percentage) of the sum of the horizontal lengths of the sections of the
evaluation profile that fall between the 2 slice levels and the evaluation length.
Specify the X-coordinate on the ADC. You can confirm the Z-coordinate against the
specified X-coordinate.
There are 2 ways of specifying the X-coordinate: touching the graph and entering the
coordinate values.
■ Specifying the Z-coordinate by touching the graph (Refer to 16.1 "■ Accessing the Analyze Graph screen".)
