Analog Video Testing.pdf

Analog video component signals are still used in home consumer devices, despite the rise of digital video interfaces. The GBR and YPbPr color systems are used, with level, synchronization, and test signals being crucial aspects. Relevant standards and test scenarios, including set-top boxes, DVD players, and laptops, are considered.

The R&S VTC, VTE, VTS, and BTC video analyzers are used for testing, with preparatory steps, configuration, and test parameter setup being essential. Automated measurements include amplitude and delay, linear distortions, nonlinear distortions, frequency response, noise measurements, timing, and jitter.

Key measurements include luminance bar amplitude, sync pulse amplitude, color bar amplitude, inter-channel amplitude and delay, 2T pulse measurements, short-time distortion, nonlinearity, and signal-to-noise ratio. The Rohde & Schwarz combined test pattern and mapping of measurements and test signals are also provided.

The application note covers the fundamentals of analog component signals and provides an overview of the tests and measurements needed, with a focus on the R&S video analyzers. It includes detailed information on test scenarios, automated measurements, and key parameters, making it a comprehensive resource for testing analog video component signals.
