Agilent / Keysight DSA91304A Infiniium High Performance Oscilloscope: 13 GHz

The Agilent/Keysight DSA91304A Infiniium High Performance Oscilloscope delivers 13 GHz true analog bandwidth for high-speed digital design and validation. With 4 analog channels, up to 40 GSa/s sample rate, and deep acquisition memory up to 1 Gpts per channel, this instrument captures complex signals with exceptional fidelity. Advanced triggering, protocol decode across multiple serial standards, and integrated jitter analysis make it ideal for signal integrity characterization and compliance testing.
