Product Description

H Large 12.1 inch XGA Touch Screen Display and CD-R/W drive (DVD Read

only)

Targeted to meet the needs of video professionals developing, testing, and
manufacturing the next generation of Digital Television reception and play--out
devices, PC and play-out devices, the instrument incorporates the power,
features, and functionality needed in R&D, QA, and Production Test applica­tions. It enables manufacturers to ensure that DTV video signal (Option SD/HD),
and PC video signal (Option VGA) quality is up to the challenge of high
performance displays, and to clearly differentiate between input signal and
display device impairments.

You can use the VM Series Video Measurement System for the following
purposes:

H R&D

H Compliance and certification testing

H Quality/Audit testing

H Installation and Troubleshooting

H Automated production test

H Off-air video systems testing

The VM Series System automates a variety of component analog video
measurements which verify the integrity and quality of DTV video signals
(Option SD/HD) and PC video signals (Option VGA).

The VM Series System automatically assesses conformance of selected video
signal parameters to applicable EIA--770--3 (for HD), SMPTE --274M, and 296M
standards (Option SD/HD), or the VESA version 1 revision 2 standard (Option
VGA).

The VM Series System also automates measurement of other industry-standard
video parameters that quantify the performance of PCs or other consumer video
reception and play-out devices with component analog interfaces.

By integrating automated measurement algorithms and a high-speed, wide
bandwidth signal acquisition platform into one instrument, Tektronix offers a
reliable means to make fast, objective, and accurate video measurements.
Product verification activities that previously took hours or days to complete can
now be completed in seconds or minutes. Offering near plug-and-play video
measurement capability, even unskilled operators can reliably assess PC video
output signal quality.

As a fully integrated video analyzer, the VM Series System offers configuration
menu settings that can readily be recalled or copied, eliminating complicated
oscilloscope setups, tedious manual measurements, and time-consuming results

correlation exercises. Product quality is enhanced because test results can be
reliably generated, easily replicated with other VM Series System instruments,
and readily communicated across a global engineering, supply, or sales
organization.

The DTV formats from 480i through 1080i and either RGB or YP bPr color
space are supported in Options SD and HD. Option VGA supports common
analog RGBHV signal resolutions from 640x480p though 2048x1536p, and
refresh rates from 50 Hz through 100 Hz. The highest refresh rate for option
VGA is 120 Hz and the highest resolution is 2048X2048.

The VM Series System runs the Windows operating system, which provides for
easy operation with minimal training time. A 12.1 in (307 mm) color display
provides a bright, clear, and crisp display of waveforms and measurement
results.
