The Keysight (formerly Agilent / HP) 54750A is a modular, high-bandwidth digitizing oscilloscope mainframe that provides high-performance equivalent-time sampling. Designed for characterization of high-speed, low-level electrical and optical signals, it features a 2-slot architecture supporting up to four acquisition channels, TDR/TDT capabilities, and exceptional timebase stability for precise jitter analysis.
