The Agilent/Keysight 16804A is a 136-channel portable logic analyzer built for signal capture and timing analysis in complex digital debug environments. It combines flexible memory architecture with dual-mode acquisition—timing and state analysis—on a 15-inch color LCD display. Engineers can scale memory from 1 M to 32 M samples as requirements evolve, while timing zoom reaches 4 GHz at 64K depth and conventional timing operates at 1.0 GHz across full channel capacity.
