HP / Agilent 54846A 4-Channel, 2.25GHz Infiniium Oscilloscope

The HP/Agilent 54846A is a 4-channel digital oscilloscope delivering 2.25 GHz analog bandwidth and 8 GSa/s real-time sampling for high-speed signal capture and analysis. Built on the Infiniium platform, this instrument combines a straightforward analog-like front panel with a Windows-based GUI, enabling both intuitive hands-on operation and access to advanced measurement functions. The 8-bit ADC provides vertical resolution across a voltage range of 2 mV/div to 2 V/div, with selectable 1 MΩ or 50 Ω input impedance. Rise time performance reaches 156 ps at 50 Ω and 700 ps at 1 MΩ, supporting analysis of fast transient events.
