Keysight (Agilent) 16823A 102-Channel Portable Logic Analyzer

The Keysight (Agilent) 16823A is a 102-channel portable logic analyzer combining state and timing analysis with integrated pattern generation for digital circuit validation in laboratory and field environments. The instrument delivers simultaneous high-speed measurements across all channels using a parallel acquisition architecture, eliminating measurement tradeoffs common in traditional designs.
