Description and Applications of the Test Patterns
The Fluke 54200 TV Signal Generator provides 16 basic test patterns. Most of these are
provided in different versions. It is also possible to combine several test patterns. The test
patterns are used for checking and alignment of monochrome and color television sets, VCRs,
and video equipment. Colored and B/W patterns are available. Every test pattern is available
in 16:9 and 4:3 aspect ratio format. The following description and suggestions show how the
test patterns can be applied to full advantage.
Where primary color signal levels for the test patterns are mentioned, for example 100/0/75/0,
these levels are according to ITU Rec. 471-1/1994. For further information, see
Appendix E, ‘Nomenclature of Color Bar Signals.’
