The Tektronix Matrix pattern uses a 100% color bar signal to test the full dynamic range of each component. The color bar
pattern is l
ocated near the top of the matrix pattern; the line numbers at which it occurs are different for each format. The
following tables show the line numbers on which the different patterns in the Matrix signal are located for a 60 Hz refresh rate.
For other refresh rates, the actual starting line number can be noticeably different than the 60 Hz rate. To view the active
video line n
umber location for a specific p attern at another refresh rate, locate the Microsoft Excel file, Matrix.xls, loc ated on
the VM Series system software CD. This file that lists the actual Active Video line numbers for all supported refresh rates.
