Comprehensive Component Analog Video
Signal Analysis
The VM6000 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 troubleshooting and design optimization. Enabled
by such broad and thorough signal analysis, the VM6000 is able to identify
relevant video signal impairments, verify compliance with applicable
standards, and ensure operability with connected displays.

Measurement parameters have been appropriately selected for testing
TV signals (Options SD and HD) and PC graphics signals (Option
VGA). These parameters vary by application because of differences
in hardware technology, signal attributes, applicable standards, and
historical test methodology. TV test measurements are based on the
de facto industry standard VM700T and have been adapted to assess
distortions unique to digital devices and HDTV signals. The PC graphics
measurement set delivers fully automated VESA compliance testing and
video measurements, as well as reporting other parameters commonly
utilized to characterize PC graphics device performance.
