Agilent/Keysight 16556A

The Agilent/Keysight 16556A is a 68-channel logic analyzer module that extends the capabilities of compatible mainframes for advanced digital system debugging and validation. This module delivers 1 Megasample per channel memory depth with dual clocking modes—state analysis at 100 MHz and timing analysis up to 500 MHz (2 ns resolution)—enabling simultaneous, time-correlated acquisition across mixed signal types. The instrument supports up to 2048 levels of sequence triggering and real-time pattern recognition, making it suitable for complex digital circuit characterization.
