Automated Video Measurement Set

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 VM5000 Option VGA,
the first and only “VM” class solution for
PC graphics signals and devices. Option
VGA automates signal analysis and man-
datory VESA standards compliance testing,
speeding design validation testing that is
typically performed with the release or modi-
fication of PC graphics hardware, software
or integration of complete video system.
Option VGA supports pervasive analog
RGBHV signal formats typically communi-
cated via VGA, DVI-I or DVI-A interfaces.
Automated measurement is possible for 11
standard signal resolutions spanning from
640x480p (VGA) through 2048x1536p
(QXGA), at selected vertical refresh fre-
quencies from 50 to 120 Hz. Because
non-standard signal resolutions, vertical
refresh frequencies or blanking are
common with analog RGBHV signals,
Option VGA offers capability to automati-
cally test unsupported video formats. 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
VM5000 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 proce-
dures, 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 five minutes.
Pre-loaded 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 auto-
matically generated, printed and saved.
An innovative set of PC graphics matrix
test signals has been created to enable
comprehensive signal characterization for
the full range of supported formats. These
signals, working in concert with a remote
controlled measurement interface unit,
