Agilent / Keysight DSOZ254A Infiniium Oscilloscope: 25 GHz

The Keysight DSOZ254A Infiniium Oscilloscope delivers 25 GHz analog bandwidth - upgradable to 63 GHz - for high-speed signal characterization in research, development, and production environments. This four-channel instrument captures signals at up to 80 GSa/s with deep acquisition memory spanning 2 Gpts total, enabling extended waveform analysis without compromise. noise performance (1.73 mVrms at 50 mV/div) and 100 fs typical jitter measurement floor ensure signal fidelity critical for precision measurements. The DSOZ254A runs Windows-based Infiniium oscilloscope software and integrates with PathWave Calibration Advisor and optional protocol decode/trigger capabilities across automotive, embedded, low-speed, MIPI, military, and advanced PCIe standards.
