Automated VESA Compliance Testing for
Analog RGBHV Signal Formats (Option VGA)
The emergence of IP broadcast video and convergence of traditional “TV”
and “PC” video entertainment devices have resulted in PCs evolving into
media gateways to the digitally connected home. As a result, assessing
the fidelity and conformance of analog RGBHV signals has become more
important to engineers involved in the design and manufacturing of PC
graphics devices. This challenge has been further complicated by the
emergence of digital interfaces, proliferation of supported output modes,
and the persistence of analog RGBHV interfaces on PC graphics cards.
Tektronix addresses these industry test requirements with the VM6000
Option VGA, the first and only “VM” class solution for PC graphics signals
and devices. Option VGA automates signal analysis and mandatory VESA
standards compliance testing, speeding design validation testing that
is typically performed during the release or modification of PC graphics
hardware, software, or integration of complete video systems.
Option VGA supports pervasive analog RGBHV signal formats typically
communicated through VGA, DVI-I, or DVI-A interfaces. Automated
measurement is possible for 10 standard signal resolutions spanning from
640x480p (VGA) through 2048x2048p (QXGA), at selected vertical refresh
frequencies from 60 to 120 Hz. A user-defined format configuration utility
enables users to easily create, edit, or recall custom modes and seamlessly
access the full test automation of the VM6000 instrument.
Approximately 150 video measurements can be performed for each
supported mode, delivering a comprehensive assessment of RGB video
fidelity, HV Sync quality, and format conformance. Parameters and test
methods are based on industry standard (VESA) test procedures, enabling

easy comparison against the requirements of the Video Signal Standard
(VSIS) and applicable DMT, GTF, or CVT timing standards. Convenient
averaging and configuration controls deliver the flexibility to perform either
speedy or precise measurement in accordance with VESA sampling
requirements. A full suite of comprehensive RGBHV video parameters
can be measured in less than 5 minutes. Preloaded signal reference data
and tolerance limit files simplify results analysis, eliminating laborious
spreadsheet entry and computation. Test results, and even waveform
screen captures can be quickly documented with reports that can be
automatically generated, printed, and saved.
