5.1.6.1 <F> Focus
When adjusting the focus, the local control terminal acts as a digital oscilloscope, graphically
representing the voltage level output by the CCD.
When you press <F> for Focus, a display similar to that in Figure 5-15 will appear.
Pixel 2634 in Camera 2
The menu and status line at the bottom of the screen allow you to specify which camera to
check, to start the data capture display at a specific pixel within the selected camera, and to
choose the method of data sampling. You may also search for an event, such as the transition
from a dark mark to light background, where the voltage would increase. You can also display
an absolute pixel position, defined in terms of the distance from the beginning of the scan line.
The current settings are displayed at the bottom of the screen.
Press <C> to select the "Current Camera" (the one you wish to view). The cursor will then be
positioned over the camera number and you may enter the new numerical value (0 through 7,
depending on your system).
