Agilent / Keysight DSO91304A Infiniium High Performance Oscilloscope: 13 GHz

The Agilent/Keysight DSO91304A Infiniium is a 13 GHz bandwidth oscilloscope engineered for advanced signal analysis of high-speed digital buses and complex RF signals. Built on a Windows-based platform with 4 analog channels, 40 GSa/s sampling, and up to 1 Gpts memory depth, this instrument delivers noise performance and deep jitter analysis capabilities. The compact 15-inch display and modular architecture support third-party software integration for protocol analysis, compliance testing, and serial bus characterization.
