Keysight UXR0254A 25GHz, Real-Time Oscilloscope

The Keysight UXR0254A is a 25 GHz real-time oscilloscope delivering four full-bandwidth channels for high-speed signal analysis. With a 10-bit ADC, 128 GSa/s sampling across all channels, and intrinsic jitter under 25 fs (rms), it captures complex waveforms with exceptional fidelity. Bandwidth extends to 110 GHz through upgradable configurations, while memory depths reach 2 Gpts for extended capture windows. The instrument combines a noise floor below 1 mVrms, inter-channel jitter under 10 fs (rms), and advanced three-stage trigger sequences—including hardware pulse-width triggers as narrow as 50 ps and software triggers at 40 ps—to isolate critical events in demanding measurements.
