The Keysight DSO90804A Infiniium is an 8 GHz real-time oscilloscope built for signal integrity analysis, high-speed digital design, and research environments where precise waveform capture and deep memory are essential. This four-channel instrument delivers 40 GSa/s sampling across all channels with up to 1 Gpts memory depth, enabling engineers to capture complex signals over extended time windows—up to 25 ms at maximum sample rate. With a noise floor of 1.15 mVrms at 50 mV/div and ±2% DC gain accuracy, the DSO90804A provides the measurement fidelity demanded by compliance verification, design debug, and advanced signal analysis workflows.
