Agilent/Keysight 1662CS

The Agilent/Keysight 1662CS is a benchtop logic analyzer that combines state and timing analysis with an integrated 2-channel oscilloscope for debugging and validation of digital systems. Engineers can perform simultaneous logic and analog measurements, capture state transitions and timing violations, and correlate captured data with processor mnemonics and C++ source code for accelerated fault isolation.
