Zoom 

The 

ZOOM 

control allows the user to zoom in and out of the input image. Zooming in enlarges the input image when 

viewed on the output video monitor. Zooming out shrinks the input image when viewed on the output video monitor. 
The center of the output video image remains fixed during zoom operations.  
 
Zoom is not available if FREEZE is enabled,  test patterns are being generated, or no video input source is available. 
 
The limiting amount of zoom possible is a function of the video parameters of the input image source, output display 
format, and under scans. Therefore, different combinations of these parameters will yield different minimum and 
maximum zoom limits. 100% zoom is full screen (when underscan is set to 0%). 
 
The under scan setting defines the usable area of the output screen and zoom will maintain that area. 
 
When the 

ZOOM

 hot key is pressed, the button illuminates and remains lit while the zoom functions are in effect. The 

following control is displayed: 
 
 
 
 
 
 
 
 
 
 
 
 
 
The zoom setting can be adjusted by turning the knob. The slide bar updates to indicate the currently selected zoom 
and the output video monitor will update as the knob is turned. When the desired zoom is attained, pressing the SEL 
key will save the zoom value and return to the system status screen. Pressing ESC will cancel the zoom operation, 
restore the previous zoom setting, and return to the system status screen. Pressing another hot key will save the 
current zoom setting, turn off the zoom LED, and display the requested hot key menu. 
 
When not in the Zoom or the Pan Menu, pressing the Pan and Zoom hot keys simultaneously will cancel any zoom 
and pan settings and immediately restore the output to the full screen setting. 
 

Pan  

Pan adjustments allow the input image to be moved on the output video device. This operation is typically used to 
center a specific area of interest on the output video monitor and then zoom in until the area of interest fills the output 
image. Pan allows the image to be moved in 0.1% steps. A positive pan movement is right or down; negative 
indicates left or up. 0% pan is the center of the screen. The underscan setting is maintained during pan operations. 
 
Pan is not available if FREEZE is enabled, test patterns are being generated, or an active input video source is not 
available. 
 
Pan is selected by first pressing the 

PAN

 hot key on the front panel, which causes the following menu to be 

displayed:
