Keysight (Agilent) 54855A Infiniium Oscilloscope 6GHz, 4CH, 20GSa/s

The Keysight (Agilent) 54855A Infiniium Oscilloscope delivers 6 GHz hardware bandwidth with four analog channels and 20 GSa/s sample rate on all channels simultaneously. Purpose-built for high-speed signal analysis and transient characterization, this instrument captures fast-edge events and high-frequency signals with minimal aliasing. Trigger jitter as low as 1.0 ps RMS enables precise timing measurements.
