Complicated instrument setups, algorithm
selection, programming and other unde-
sirable aspects of making video measure-
ments are eliminated with the VM5000.
Configuration is as simple as selecting
the video format and measurement
parameters from an on-screen menu,
eliminating complicated instrument
setups, tedious manual measurements
and time-consuming results correlation.
These test configuration settings can be
readily saved, recalled or copied, further
simplifying test of multi-format video
devices. Users wanting to make manual
measurements can exit the automated
measurement application and then
access a full-featured oscilloscope.
Supports SD, HDTV and RGBHV
Component Analog Video Formats
The VM5000 can be flexibly configured to
support any combination of component
analog SD, HDTV and RGBHV video
formats with the available options. Broad
format support enables automated test of
digital set-top boxes, video semiconductors,
DVD players, PC graphics cards and other
consumer video devices.
Bandwidth and Sample Rates
Suitable for HDTV and High
Resolution PC Graphics Signals
The VM5000 utilizes a digital phosphor
oscilloscope platform as the basis for
signal acquisition and analysis. Utilizing
proven, high-speed measurement archi-
tecture, Tektronix surpasses the limitations
of current video analyzers to address the
evolving needs of the video industry. The
VM5000 offers over 1 GHz of bandwidth
and 1.25 GS/s maximum real-time sample
rates per channel to easily meet stringent
HDTV measurement demands – easily
assessing frequency response for signals
up to and well beyond 30 MHz. The high
sample rates and low noise floor of the
instrument enable noise measurement
accuracy that was previously impossible
on HDTV signals. A rise time of less than
400 ps and superior time-base perform-
ance are sufficient to make critical sync
and rise time measurements as required by
EIA-770 and SMPTE 274M and VESA.
A large record length and high sample
rates deliver measurement results with
minimal time lag.
Comprehensive Component
Analog Video Signal Analysis
The VM5000 incorporates an extensive set
of automated video measurements that
deliver comprehensive characterization of
the fidelity and conformance of component
analog signals. Approximately 150 individual
measurements completely characterize
video signal amplitudes, timing and noise
distortions into parameter categories that
are easily understood, facilitating trouble-
shooting and design optimization.
Enabled by such broad and thorough signal
analysis, the VM5000 is able to identify
relevant video signal impairments, verify
compliance with applicable standards and
ensure operability with connected displays.
