New and Unique Method for Measuring Video Analogue Component Signal Parameters

Based on the growing need to distribute and process the video signal in analogue component form, a means of simultaneously monitoring at least three component signals is needed. A traditional voltage versus time display of the signals in sequence (parade) is quite useful for monitoring and measuring a number of signal parameters. In the case of RGB components, the parade display is typically used and illustrates amplitude, transient response (group delay), and frequency response errors in any or all of the components. Relative errors in amplitude and timing are more difficult to measure with the parade display unless the waveform monitor can be adjusted to overlay the component signals on top of one another. The display can then be expanded vertically and horizontally to provide the resolution needed for precise timing and amplitude comparisons.
