Comprehensive Component Analog Video

Signal Analysis

The VM6000 incorporates an extensive set of automated video

measurements that deliver comprehe nsive characterization of the ﬁde lity

and conformance of component analog signals. Approximately 150

individual measurements completely cha racterize video signal amplitudes,

timing, and noise distortions into paramet er categories that are easily

understo

od, facilitating troubleshooting and design optimization. Enabled

by such broad and thorough signal analysis, the VM6000 is able to identify

relevant video signal impairments, verify c ompliance with applicable

standards, and ensure operability with connected displays.

Measurement parameters h ave 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 me thodolo gy. TV test measurement s are based on th e

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 perfo rmance.
