Keysight (Agilent) 16806A 204-Channel Portable Logic Analyzer

The Keysight 16806A is a 204-channel portable logic analyzer designed for digital system debugging, validation, and signal integrity analysis. It combines deep memory acquisition, multiple timing modes, and advanced triggering capabilities to support complex digital designs from low-speed state analysis through high-speed asynchronous timing measurements. The 15-inch color display and touch-screen option enable flexible lab and field deployment.
