HDTV Matrix Test Signal in 16x9 Aspect Ratio
HDTV Matrix Test Signal
A specific matrix test signal has been created to enable efficient and
comprehensive test of component analog video signal fidelity. The matrix
signal includes a range of test signals on different lines to enable video
testing without the inconvenience of switching full field signals, and contents
have been customized to exercise the full bandwidth capability of each
format. One signal can be flexibly utilized for both RGB and YPbPr color
spaces, thereby minimizing test signal proliferation.
The HDTV matrix test signal is supplied in a variety of file and signal formats
to enable convenient and comprehensive test of set-top boxes and other
consumer video devices. High-quality encoded ATSC Transport Stream and
compressed Elementary Stream files are supplied for easy playout on a
Tektronix MPEG player such as the RTX100B, RTX130B, or MTX100B.
PC Graphics Matrix Test Signal
VESA compliance and certification testing requires that several different
types of test signals be applied to the device under test. Option VGA
PC Graphics Matrix Test Signal (Option VGA)
includes test signal files for these patterns, in both full field and matrix
forms for the full range of supported image resolutions. Test signal files are
provided in .bmp and .png file formats.

because they enable HV timing measurements to be made without the
border artifacts potentially introduced by bitmap files.
