(1)Norm

Image observation mode

(2)Line

Displays a line profile of the signal intensity as a horizontal line in the observed image. This control toggles between the 1 (position setting) and 2 (line analysis) modes.

(3)Spot

Stops the scanning and places the electron beam at a specified point on the image. Used for X-ray analysis of a point on the specimen.

This control toggles between the 1 (position setting) and 2 (line analysis) modes.

(4)Area

Scans the electron beam in a selected frame in the image.

An advantage to this is that it allows an area-averaged spectrum as the beam is scanned over a specified area, greater than the beam spot. Another advantage is that it reduces the likelihood of specimen contamination in comparison with the stationary beam in Spot Analysis mode.

This control toggles between the 1 (position setting) and 2 (line analysis) modes.
