2.3.6.3  R.ROTATION block 
 
Controls electron beam scanning direction to rotate image.   
 
 
 
 
 
 
To activate raster rotation, check the ON/OFF check box. 
Rotation angle can be set with the slider, clicking the side of slider, clicking the Angle adjust 
button or with 90°step rotate button.   
 
 
2.3.6.4  SCAN MODE block 

 

Selects a scanning mode 

 
 
 
 
 
 

(1) Normal 

Image observation mode 
 

(2) Line 

Displays a line profile of the signal intensity as a horizontal line in the observing image. 
 

(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. 
 

(4) Area 

Scans the electron beam in a selected frame in the image. 
Used for X-ray analysis of a specified area on the specimen. 
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.

Beam monitor is active when the box is checked.
