980 DP 1.4 Video Generator / Analyzer - User Guide

16.117.5

 

Test   

Yoke winding orthogonality check. 

16.117.6

 

Purpose 

 

The horizontal and vertical deflection coils on the yoke should have their axes cross at exactly 90 degrees. 
Improper orientation of the windings causes displayed rectangles to look more like nonorthogonal parallelograms. 
This type of defect is almost impossible to correct with adjustments. It is usually easier to replace the defective 
yoke. 

16.117.7

 

Method 

First, perform the yoke tilt correction described above. The vertical center line of the image should be perpendicular 
to the work surface. If the deviation is beyond specification, the monitor should be rejected and sent back for repair, 

rather than trying to magnet a defective yoke. 

16.117.8

 

Test   

Display size correction. 

16.117.9

 

Purpose 

 

A too-large active video size adjustment on a monitor may cause information to be lost around the edges of the 
screen. A too-small active video size adjustment may make some displayed information hard to read. The correct 
size is needed to obtain the correct aspect ratio. You need the correct aspect ratio to get round circles and square 
squares. 

16.117.10

 

Method 

 

First, determine the correct physical size of the active video area for the display. This information usually is given in 
a display

’s specification sheet or service manual. The size should match the sizes in the format you are using. The 

size setting of the current format can be checked using the 

Format 

test image. 

Place a ruler or gauge along the horizontal line of the image and adjust the monitor's horizontal size control until 
the distance between the end points matches the specified value. 

Move the ruler or gauge to the vertical line and adjust your monitor's vertical size control until the distance between 
the end points matches the specified value. 

16.117.11

 

Test   

Parallelogram distortion check. 

16.117.12

 

Purpose 

 

Parallelogram distortion is very difficult to correct with magnets because the correction often causes barrel 
distortion. Therefore, you should decide early whether your monitor meets this specification. The problem usually 
can be traced to the improper winding of the yoke coils. If the problem is not too severe, it may be corrected by 
adding or adjusting magnets on the yoke. However, if the distortion is excessive, it may be an indication of a 
defective yoke which cannot be corrected with magnets.
