Agilent / Keysight DSOS254A High-Definition Oscilloscope: 2.5 GHz, 4 Analog Channels

The Keysight DSOS254A is a high-definition oscilloscope built for precision signal analysis across 2.5 GHz bandwidth with four analog channels. Its 10-bit ADC and high-resolution vertical digitization deliver an average system ENOB of 8.1 bits at full bandwidth, enabling capture of subtle signal details. The instrument acquires up to 20 GSa/s on two channels or 10 GSa/s across all four channels, with standard memory of 100 Mpts per channel, expandable to 800 Mpts.

A 172 ps rise time ensures accurate edge characterization. The 15-inch XGA capacitive touch screen provides intuitive navigation, while the solid-state drive enables rapid boot-up and enhanced reliability.
