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.

– Compatibility & Integration
The 69771A installs into Agilent and Keysight modular chassis platforms. Operation requires appropriate drivers and software support—typically Keysight’s IO Libraries Suite or host-specific drivers compatible with installed test executive software. Verification of chassis compatibility prior to procurement is essential.
