Agilent/Keysight 54854A

The Agilent/Keysight 54854A is a 4 GHz digital oscilloscope engineered for signal integrity validation in telecommunications, semiconductor design, and digital systems development. This Infiniium 54800 series instrument captures and analyzes complex waveforms with 4 analog input channels, 20 GSa/s simultaneous sampling across all channels, and up to 32 Mpts acquisition memory at reduced sample rates. The Windows-based interface streamlines both real-time troubleshooting and detailed design verification workflows.
