Agilent / Keysight DSO9254A Oscilloscope: 2.5 GHz, 4 Analog Channels

The Agilent/Keysight DSO9254A is a 2.5 GHz digital storage oscilloscope delivering four analog channels with integrated logic and protocol analysis capabilities. This Infiniium 9000 Series instrument combines oscilloscope, logic analyzer, and protocol analyzer functionality in a single platform, enabling efficient signal acquisition and debug workflows across demanding applications. The DSO9254A acquires waveforms at up to 250,000 per second with deep memory architecture supporting up to 1 Gpts per channel (upgradeable), maintaining high sample rates across extended capture windows. A 15-inch XGA touchscreen provides intuitive control and clear signal visualization.
