The Tektronix DSA70404 is a high-performance Digital Serial Analyzer (oscilloscope) designed to address the challenges of high-speed serial design verification, characterization, and debugging. Part of the DSA70000 series, it combines a 4 GHz analog bandwidth with a real-time sample rate of 25 GS/s across all four channels simultaneously. It features Pinpoint® triggering, dedicated serial pattern triggering up to 3.125 Gb/s, and a large 12.1-inch touch display, running on an open Windows platform to enable advanced signal integrity analysis and compliance testing.
