The Agilent/Keysight 1661ES is a benchtop logic analyzer that combines digital state and timing analysis with integrated dual-channel oscilloscope functionality. This single instrument enables simultaneous capture and display of both logic and analog signals, eliminating the need for separate test equipment on the bench. The 1661ES addresses the validation requirements of engineers developing embedded systems and signal integrity analysis.
