The Keysight (Agilent) 16903A is a modular logic analysis system mainframe designed for system-level debugging of digital designs. Its 3-slot architecture accepts customizable measurement modules to reach up to 204 channels, depending on configuration. The platform features a 12.1-inch color LCD touch screen (800 × 600 resolution) running Windows XP Pro, with multiple data views including waveform, listing, packet viewer, source code, and compare displays. Operators control the system via dedicated hotkeys, knobs, keyboard, and mouse input.
