Agilent DSO81004A 10GHz Digital Signal Oscilloscope

The Agilent DSO81004A is a 10 GHz real-time digital signal oscilloscope engineered for high-speed serial data analysis, signal integrity characterization, and compliance verification. With 4 simultaneous channels, configurable sample rates up to 40 GSa/s, and acquisition memory expandable to 256 Mpts per channel, it delivers the capture depth and speed required for complex digital signal examination. Real-time eye diagram generation, comprehensive jitter decomposition, and over 50 automatic measurements enable rapid identification of timing errors and signal quality issues across multiple domains.
