3. A spectroscopic measurement is recorded.
4. The Z-Controller is turned on again.
5. The tip is moved to the next point on the line in the XY-plane.
Steps 2.-5. are repeated for each points on the line.
Spectroscopic measurement sequences are controlled using the Spectros-
copy window. The Spectroscopy window can either be opened by clicking
in the navigator, or by clicking in the Imaging bar. When the
Spectroscopy window is activated from the Imaging bar, the currently
measured image is transferred to the Spectroscopy window.
The Spectroscopy window contains the Spectroscopy bar, with commands
that control the spectroscopy processes, and the Spectroscopy panel, with
parameters that determine how the spectroscopy measurement is done.
The Spectroscopy window also contains a number of charts that display the
data from a previous imaging measurement and the data from the ongoing
spectroscopic measurement. The Spectroscopy window can display as many
charts as the size of the window can accommodate. It is recommended to
display at least two charts, one a Color map of a previous Topography meas-
urement of the area where the spectroscopy measurement is performed, and
one a Dual Line graph of the current spectroscopy measurement. For more
information on adding and changing charts (chapter
Viewing measurement
data (p.134)).
The Spectroscopy bar
/
starts a spectroscopy measurement sequence and then changes to
until the measurement sequence is finished. Clicking
aborts the
measurement sequence as soon as the current modulation period is fin-
ished.
/
Starts the selection of the XY measurement position(s) in a topography
Color map chart using the mouse cursor. These positions are automatically
transferred to the appropriate entries in the Position section of the Spectros-
