REFERENCE/MEASUREMENT CURSORS
The reference ( R ) cursor and measurement ( M ) cursor define the portion of the profile trace for
leveling or performing analytical functions. You can adjust the bandwidth at each cursor to average
the data points within the cursor’s bandwidth. This is useful for leveling and average step height
measurements.
NOTE –
Veeco recommends that you do not use zero (0) bandwidths unless you want point-
to-point measurements. Such measurements can vary substantially from the averaged results
that you get with non-zero bandwidths.
BASIC CURSOR POSITIONING
Cursor positioning is critical for obtaining accurate results. The simplest way to reposition the cursors
is to use the mouse to drag the
R and M cursor flags at the top of the cursors to new positions in the
data plot.
Selecting both R and M cursors allows you to reposition the cursors while maintaining the same
distance between them. Hold down the
C
TRL
key while dragging with the left mouse button on the R
or M cursor flag. Now dragging either flag causes both cursors to move simultaneously.
