The Keysight DSO90254A Infiniium is a 2.5 GHz high-performance oscilloscope engineered for advanced signal analysis in demanding electronic testing and design workflows. Built around four analog channels, this instrument captures signals at up to 20 GSa/s simultaneously across all channels, with memory depths ranging from 20 Mpts to 1 Gpts per channel. The 8-bit vertical resolution expands beyond 12 bits with averaging, enabling precise voltage measurement from 1 mV/div to 1 V/div across a ±5 V maximum input range. Real-time timebase spans 5 ps/div to 20 s/div; equivalent-time operation extends to 5 ps/div. Rise time measures 140 ps (10-90%), with noise floors of 0.64 mVrms at 50 mV/div and 1.21 mVrms at 100 mV/div.
