Keysight (Agilent) 1680AD Standalone Logic Analyzer

The Keysight (Agilent) 1680AD is a standalone logic analyzer built for real-time capture and analysis of complex digital signals in embedded systems, ASICs, and digital designs. The integrated 10.4″ or 12.1″ color LCD display and embedded GUI eliminate the need for external PC dependency during basic operation. Engineers gain access to advanced triggering, state and timing analysis modes, and protocol decode capabilities—all from a self-contained instrument.
