Automated Video Measurement Set
VM5000
Picture, Vector and
Waveform Displays
Picture and Vector displays can be initiated
with a single button push and deliver “at-a-
glance” confidence checking that simplifies
signal identification, troubleshooting and
color conversion accuracy. Waveforms
are simultaneously displayed with para-
metric test results to enable visualization
of signal impairments.
By selecting Picture mode, a full color
picture display is rendered on screen from
the connected sub-sampled and down
converted signals to the available picture
area and resolution. Pictures by default
appear in an appropriate 16x9 or 4x3
aspect ratio; however, users can resize,
move or minimize the window as needed.
Picture mode incorporates a user-enabled
bright line select feature to facilitate test
configuration. Live or full motion video
signals can also be viewed at vertical
refresh rates of 1 to 2 fps.
The Vector display, available with Option
SD and HD, displays the waveform with
targets for 75% or 100% color bars
and accommodates either 601 or 709
colorimetry targets. Graticule targets and
color space can be selected automatically
or manually.
Waveforms for all channels are simultane-
ously viewable in different colors, and
display can be zoomed both vertically and
temporally for detailed examination and
analysis. Users can selectively expand the
waveform to the full display size by mini-
mizing the measurement application.
Time-saving Test Utilities
and Results Displays
The VM5000 offers a powerful combination
of test utilities and custom displays to make
HDTV video test faster, more robust, more
convenient and more accurate. These
utilities supplement basic automated
measurement capabilities to deliver
performance and value unmatched by
any other solution. Combined with the
extended documentation utilities, these
powerful automated measurement utilities
and features ensure that the VM5000 meets
the demands of all application areas.
Research and Development, Quality
Control and Production Test personnel
can tailor the instrument settings to meet
their particular needs for robust acquisition,
speed or accuracy. By automating meas-
urement functions, video professionals are
ensured that automatic measurements
are robust, accurate, repeatable and
completely objective.
Summary Test Results Display – For
the ultimate in test progress and reporting,
the VM5000 incorporates a summary test
results display screen. This display enables
operators to monitor test progress and
acceptability of video signal parameters
without having to delve into complicated
individual test results. Each of the selected
test parameters, measurement progress,
pass or fail result per parameter and test
errors, if any, are displayed. Upon comple-
tion, an overall green or red measurement
result flag is displayed.
Integrated Pass-fail Limit Testing –
The VM5000 incorporates user-selectable
pass-fail limit testing. Acceptability of indi-
vidual parameters or an entire DUT can
be assessed without browsing hundreds
of individual numerical results. Suitable for
use in stand-alone applications, there is
a PF summary screen that shows the
progress and PF result of individual meas-
urements and an overall DUT PF result
based on the selected parameters and
user-selected limits. When PF limit testing
is enabled, measurement results for failed
parameters are displayed in an intuitive
GREEN-RED numerical result for easy
identification of unacceptable or noncon-
forming signal conditions.
