Keysight / Agilent / HP 16500C Logic Analyzer Mainframe

The Keysight/Agilent/HP 16500C Logic Analyzer Mainframe is a modular digital measurement platform designed for complex debugging, validation, and timing verification across microprocessor and embedded systems applications. The mainframe accepts five internal measurement modules with expansion capability up to 10 modules via an optional HP 16501A expansion frame, build integrated solutions for state/timing analysis, oscilloscopy, and pattern generation. A 9-inch color CRT touchscreen display combined with front-panel knob, PS/2 mouse, and optional keyboard provides intuitive control, while X-Window system support enables remote operation across networks.
