The Keysight DSO81004B is a four-channel digital oscilloscope built for signal integrity and high-speed serial data analysis. It delivers 10 GHz bandwidth, upgradeable to 13 GHz, with real-time sampling to 40 GSa/s and deep memory up to 2 Mpts per channel at full sample rate. The instrument achieves industry-low noise performance—342 µV at 5 mV/div—and trigger jitter below 500 fs rms, making it suitable for jitter characterization, serial protocol validation, and precision waveform capture. An XGA touchscreen with 256 intensity levels supports detailed signal visualization across all four channels.
