The Tektronix CSA7404 Communication Signal Analyzer is a real-time oscilloscope platform engineered for physical layer characterization of optical and electrical communication signals. It delivers high-speed acquisition and analysis for backplane, midplane, and embedded designs—supporting design, development, and compliance testing up to 2.5 Gb/s rates for standards including OC-48/STM-16 and Fibre Channel FC2125. The instrument combines true analog bandwidth of 4 GHz with DPX® acquisition technology to capture signal information at rates exceeding 400,000 waveforms per second.
