CHESS BOARD TEST CHART 16:9

REFLECTANCE

The TE102 test chart is designed for checking geometry and resolution.

DATA

Similar to a chessboard the test chart is composed of 9x18 black and white square fields which are

surrounded by rectangular fields at the edges that corresponds to the 10/19 grid raster lines of

electronic test generators. (The division of the horizontal grid lines of these generators corresponds

to 58 lines per complete picture.)

Two resolution wedges in the middle of the chart allow the checking of the vertical and horizontal

resolution. The markings on the wedges are both in lines and MHz.

UTILIZATION

• Checking geometry and the congruency of rasters, by means of an electronically generated grid,

   if necessary.

• Checking the uniformity of signal generation.

• Checking resolution.

• * The frequencies given are related to the 625-lines TV standard. Charts for the 525-lines standard

have the designation TE102 N.
