Agilent/Keysight 1660CS

The Agilent/Keysight 1660CS is a portable benchtop logic analyzer that combines state and timing analysis with an integrated 2-channel oscilloscope for comprehensive digital system debugging. Engineers use it to identify and resolve hardware and software issues in embedded systems through simultaneous capture and display of state, timing, and oscilloscope data - pinpointing design errors that single-domain tools miss.
