The Agilent/Keysight 69771A is a Digital Input/Analog Comparator Card engineered for integration into modular test and measurement systems. The card provides digital input capabilities for monitoring external signals and incorporates an analog comparator function for threshold-based signal detection. It delivers precise control and monitoring of analog and digital signals within automated test equipment (ATE) environments, laboratory setups, and industrial automation platforms.
