The Keysight/Agilent/HP 54120A Digitizing Oscilloscope Mainframe is a modular platform for high-speed signal acquisition and analysis. Operating to 20 GHz bandwidth with sampling rates up to 80 GSa/s, it delivers the vertical resolution and timing accuracy required for precision measurements in advanced electronics and communications. The mainframe accepts plug-in modules for customization—including Time Domain Reflectometry (TDR) capability—and provides basic, statistical, and network measurement functions.
