The Tektronix WFM7A SDI Input Module is designed to add two additional SDI inputs to WFM700-series waveform monitors. It supports standard-definition (SD) video input monitoring with features such as pixel-level image quality checking. The module is compatible with SD/HD-SDI auto-detection and provides precise monitoring of video signal integrity, including black and frozen frame detection. It enhances the waveform monitor’s capability by allowing simultaneous input monitoring and detailed signal analysis. The module is suitable for professional broadcast and production workflows that require reliable video signal verification.
