The Keysight DSO81304B is a 13 GHz real-time oscilloscope engineered for high-speed signal characterization across four analog channels. It delivers 40 GSa/s sample rate on two channels or 20 GSa/s across all four channels, with configurable memory depth up to 64 Mpts. The instrument combines low noise performance—419 µV at 5 mV/div—with sub-500 fs trigger jitter to enable precise measurements in telecommunications, aerospace, and research environments.
