The Keysight (Agilent) 16804A is a 136-channel portable logic analyzer designed for engineers and system integrators performing detailed digital analysis and validation of complex digital systems. The instrument combines a 15-inch color display—available with touch-screen capability—with deep acquisition memory and high-speed timing analysis to support on-site debugging and data visualization. Its portable form factor makes it suitable for product development, system integration, and field troubleshooting across a range of digital applications.
